Chen C, Zhang Y, Chen Y, Chen H, Gong R. Sweet cherry TCP gene family analysis reveals potential functions of PavTCP1, PavTCP2 and PavTCP3 in fruit light responses. BMC Genomics 2024; 25:3. [PMID: 38166656 PMCID: PMC10759647 DOI: 10.1186/s12864-023-09923-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Accepted: 12/18/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND TCP proteins are plant specific transcription factors that play important roles in plant growth and development. Despite the known significance of these transcription factors in general plant development, their specific role in fruit growth remains largely uncharted. Therefore, this study explores the potential role of TCP transcription factors in the growth and development of sweet cherry fruits. RESULTS Thirteen members of the PavTCP family were identified within the sweet cherry plant, with two, PavTCP1 and PavTCP4, found to contain potential target sites for Pav-miR159, Pav-miR139a, and Pav-miR139b-3p. Analyses of cis-acting elements and Arabidopsis homology prediction analyses that the PavTCP family comprises many light-responsive elements. Homologs of PavTCP1 and PavTCP3 in Arabidopsis TCP proteins were found to be crucial to light responses. Shading experiments showed distinct correlation patterns between PavTCP1, 2, and 3 and total anthocyanins, soluble sugars, and soluble solids in sweet cherry fruits. These observations suggest that these genes may contribute significantly to sweet cherry light responses. In particular, PavTCP1 could play a key role, potentially mediated through Pav-miR159, Pav-miR139a, and Pav-miR139b-3p. CONCLUSION This study is the first to unveil the potential function of TCP transcription factors in the light responses of sweet cherry fruits, paving the way for future investigations into the role of this transcription factor family in plant fruit development.

Genome-wide identification of the TCP gene family in Chrysanthemum lavandulifolium and its homologs expression patterns during flower development in different Chrysanthemum species. FRONTIERS IN PLANT SCIENCE 2023; 14:1276123. [PMID: 37841609 PMCID: PMC10570465 DOI: 10.3389/fpls.2023.1276123] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Accepted: 09/13/2023] [Indexed: 10/17/2023]
Abstract
TCP proteins, part of the transcription factors specific to plants, are recognized for their involvement in various aspects of plant growth and development. Nevertheless, a thorough investigation of TCPs in Chrysanthemum lavandulifolium, a prominent ancestral species of cultivated chrysanthemum and an excellent model material for investigating ray floret (RF) and disc floret (DF) development in Chrysanthemum, remains unexplored yet. Herein, a comprehensive study was performed to analyze the genome-wide distribution of TCPs in C. lavandulifolium. In total, 39 TCPs in C. lavandulifolium were identified, showing uneven distribution on 8 chromosomes. Phylogenetic and gene structural analyses revealed that ClTCPs were grouped into classes I and II. The class II genes were subdivided into two subclades, the CIN and CYC/TB1 subclades, with members of each clade having similar conserved motifs and gene structures. Four CIN subclade genes (ClTCP24, ClTCP25, ClTCP26, and ClTCP27) contained the potential miR319 target sites. Promoter analysis revealed that ClTCPs had numerous cis-regulatory elements associated with phytohormone responses, stress responses, and plant growth/development. The expression patterns of ClTCPs during capitulum development and in two different florets were determined using RNA-seq and qRT-PCR. The expression levels of TCPs varied in six development stages of capitula; 25 out of the 36 TCPs genes were specifically expressed in flowers. Additionally, we identified six key ClCYC2 genes, which belong to the class II TCP subclade, with markedly upregulated expression in RFs compared with DFs, and these genes exhibited similar expression patterns in the two florets of Chrysanthemum species. It is speculated that they may be responsible for RFs and DFs development. Subcellular localization and transactivation activity analyses of six candidate genes demonstrated that all of them were localized in the nucleus, while three exhibited self-activation activities. This research provided a better understanding of TCPs in C. lavandulifolium and laid a foundation for unraveling the mechanism by which important TCPs involved in the capitulum development.

Funct Integr Genomics 2023; 23:310. [PMID: 37743454 DOI: 10.1007/s10142-023-01239-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Revised: 09/07/2023] [Accepted: 09/18/2023] [Indexed: 09/26/2023]
Abstract
Watermelon (Citrullus lanatus) is a widely cultivated cucurbitaceae crop appreciated by consumers worldwide. However, the long vine and abundant lateral branches of currently cultivated watermelon varieties hinder light simplification and mechanized cultivation, affecting plant spacing and row spacing requirements. To address this, the development of watermelon with dwarf and branchless traits has become a crucial direction for the industry. In previous studies, the genes controlling dwarf (Cldw-1) and branchless (Clbl) traits were mapped and cloned. Marker-assisted selection markers, dCAPS3 and dCAPS10, were developed for these traits, respectively. In this study, the dwarf germplasm WM102 and the branchless germplasm WCZ were crossed to obtain F1 .Further self-crossing of the F1 individuals resulted in the F2 population. Through multiple generations of self-pollination, a new watermelon germplasm DM with double mutation (dwarf and branchless) was obtained. DM exhibited stable inheritance without segregation. Moreover, DM was used as a donor parent for crossing with commercial watermelon materials, and near-isogenic lines (NILs) with the dwarf and branchless traits were developed. These NILs carry additional desirable agronomic traits and provide valuable genetic resources for future watermelon breeding programs, particularly in improving plant architecture and overall quality. The development and application of DM and NILs hold great potential for advancing the watermelon industry toward industrialization, large-scale cultivation, and enhanced plant architecture.

Abstract
The plant-specific transcription factor TEOSINTE BRANCHED, CYCLOIDEA, AND PROLIFERATING CELL FACTOR (TCP) gene family plays vital roles in various biological processes, including growth and development, hormone signaling, and stress responses. However, there is a limited amount of information regarding the TCP gene family in roses (Rosa sp.). In this study, we identified 18 TCP genes in the rose genome, which were further classified into two subgroups (Group A and Group B) via phylogenetic analysis. Comprehensive characterization of these TCP genes was performed, including gene structure, motif composition, chromosomal location, and expression profiles. Synteny analysis revealed that a few TCP genes are involved in segmental duplication events, indicating that these genes played an important role in the expansion of the TCP gene family in roses. This suggests that segmental duplication events have caused the evolution of the TCP gene family and may have generated new functions. Our study provides an insight into the evolutionary and functional characteristics of the TCP gene family in roses and lays a foundation for the future exploration of the regulatory mechanisms of TCP genes in plant growth and development.

Abstract
TEOSINTE BRANCHED1, CYCLOIDEA, PROLIFERATING CELL FACTOR 1 and 2 (TCP) proteins constitute a plant-specific transcription factors family exerting effects on multiple aspects of plant development, such as germination, embryogenesis, leaf and flower morphogenesis, and pollen development, through the recruitment of other factors and the modulation of different hormonal pathways. They are divided into two main classes, I and II. This review focuses on the function and regulation of class I TCP proteins (TCPs). We describe the role of class I TCPs in cell growth and proliferation and summarize recent progresses in understanding the function of class I TCPs in diverse developmental processes, defense, and abiotic stress responses. In addition, their function in redox signaling and the interplay between class I TCPs and proteins involved in immunity and transcriptional and posttranslational regulation is discussed.

Genome-Wide Identification and Characterization of TCP Gene Family Members in Melastoma candidum. Molecules 2022; 27:molecules27249036. [PMID: 36558169 PMCID: PMC9787641 DOI: 10.3390/molecules27249036] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 12/14/2022] [Accepted: 12/15/2022] [Indexed: 12/24/2022] Open
Abstract
It has been confirmed that the plant-specific Teosinte-branched 1/Cycloidea/Proliferating (TCP) gene family plays a pivotal role during plant growth and development. M. candidum is a native ornamental species and has a wide range of pharmacodynamic effects. However, there is still a lack of research on TCP’s role in controlling M. candidum’s development, abiotic stress responses and hormone metabolism. A comprehensive description of the TCP gene family in M. candidum is urgently needed. In this study, we used the HMMER search method in conjunction with the BLASTp method to identify the members of the TCP gene family, and a total of 35 TCP genes were identified. A domain analysis further confirmed that all 35 TCPs contained a TCP superfamily, a characteristic involved in dimerization and DNA binding that can be found in most genes from this gene family, suggesting that our identification was effective. As a result of the domain conservation analysis, the 35 TCP genes could be classified into two classes, TCP-P and TCP-C, based on the conservative regions of 55 and 59 amino acids, respectively. Gene-duplication analysis revealed that most TCP genes were present in duplication events that eventually led to TCP gene expansion in M. candidum. All the detected gene pairs had a Ka/Ks value of less than one, suggesting that purification selection is the most important factor that influences the evolution of TCP genes. Phylogenetic analysis of three species displayed the evolutionary relationship of TCP genes across different species and further confirmed our results. The real-time quantitative PCR (qRT-PCR) results showed that McTCP2a, McTCP7a, McTCP10, McTCP11, McTCP12a, McTCP13, McTCP16, McTCP17, McTCP18, McTCP20 and McTCP21 may be involved in leaf development; McTCP4a, McTCP1, McTCP14, McTCP17, McTCP18, McTCP20, McTCP22 and McTCP24 may be involved in flower development; and McTCP2a, McTCP3, McTCP5a, McTCP6, McTCP7a, McTCP9, McTCP11, McTCP14 and McTCP16 may be involved in seed development. Our results dissect the TCP gene family across the genome of M. candidum and provide valuable information for exploring TCP genes to promote molecular breeding and property improvement of M. candidum in the future.

Abstract
The plant-specific IQ67 domain (IQD) is the largest class of calmodulin targets found in plants, and plays an important role in many biological processes, especially fruit development processes. However, the functional role of IQD proteins in the development of watermelon (Citrullus lanatus) shape remains unknown, as the IQD protein family in watermelon has not been systematically characterized. Herein, we elucidated the gene structures, chromosomal locations, evolutionary divergence, and functions of 35 IQD genes in the watermelon genome. The transcript profiles and quantitative real-time PCR analysis at different stages of fruit development showed that the ClIQD24 gene was highly expressed on 0 days after pollination. Furthermore, we found that the ectopic overexpression of ClIQD24 promoted tomato fruit elongation, thereby revealing the significance of ClIQD24 in the progression of watermelon shape. Our study will serve as a reference for further investigations on the molecular mechanisms underlying watermelon fruit shape formation.

Abstract
Thaumatin-like protein (TLP) is the well-known sweetest protein which plays a crucial role in diverse developmental processes and different stress conditions in plants, fungi and animals. The TLP gene family is extensively studied in different plant species including crop plants. Watermelon (Citrullus lanatus) is an important cucurbit crop cultivated worldwide; however, the comprehensive information about the TLP gene family is not available in watermelon. In the present study, we identified the 29 TLP genes as gene family members in watermelon using various computational methods to understand its role in different developmental processes and stress conditions. ClaTLP gene family members were not uniformly distributed on 22 chromosomes. Phylogenetic analysis revealed that the ClaTLP gene family members were grouped into 10 sub-groups. Further, gene duplication analysis showed thirteen gene duplication events which included one tandem and twelve segmental duplications. Amino acid sequence alignment has shown that ClaTLP proteins shared 16 conserved cysteine residues in their THN domain. Furthermore, cis-acting regulatory elements analysis also displayed that ClaTLP gene family members contain diverse phytohormone, various defense, and stress-responsive elements in their promoter region. The expression profile of the ClaTLP gene family revealed the differential expression of gene family members in different tissues and abiotic stresses conditions. Moreover, the expression profile of ClaTLP genes was further validated by semi-quantitative reverse transcriptase PCR. Taken together, these results indicate that ClaTLP genes might play an important role in developmental processes and diverse stress conditions. Therefore, the outcome of this study brings forth the valuable information for further interpret the precise role of ClaTLP gene family members in watermelon.

Abstract
BACKGROUND Citrus is one of the most important fruit crops in the world, and it is worthy to conduct more research on artificially controlling citrus plant growth and development to adapt to different cultivation patterns and environmental conditions. The plant-specific TEOSINTE BRANCHED1, CYCOLOIDEA, and PROLIFERATING CELL FACTORS (TCP) transcription factors are crucial regulators controlling plant growth and development, as well as responding to abiotic stresses. However, the information about citrus TCP transcription factors remains unclear. RESULTS In this study, twenty putative TCP genes (CsTCPs) with the TCP domain were explored from Citrus sinensis genome, of which eleven (CsTCP3, - 4, - 5, - 6, - 10, - 11, - 15, - 16, - 18, - 19, - 20), five (CsTCP1, - 2, - 7, - 9, - 13), and four genes (CsTCP8, - 12, - 14, - 17) were unevenly distributed on chromosomes and divided into three subclades. Cis-acting element analysis indicated that most CsTCPs contained many phytohormone- and environment-responsive elements in promoter regions. All of CsTCPs were predominantly expressed in vegetative tissues or organs (stem, leaf, thorn, and bud) instead of reproductive tissues or organs (flower, fruit, and seed). Combined with collinearity analysis, CsTCP3, CsTCP9, and CsTCP13 may take part in leaf development; CsTCP12 and CsTCP14 may function in shoot branching, leaf development, or thorn development; CsTCP15 may participate in the development of stem, leaf, or thorn. In mature leaf, transcript levels of two CsTCPs (CsTCP19, - 20) were significantly increased while transcript levels of eight CsTCPs (CsTCP2, - 5, - 6, - 7, - 8, - 9, - 10, - 13) were significantly decreased by shading; except for two CsTCPs (CsTCP11, - 19), CsTCPs' transcript levels were significantly influenced by low temperature; moreover, transcript levels of two CsTCPs (CsTCP11, - 12) were significantly increased while five CsTCPs' (CsTCP14, - 16, - 18, - 19, - 20) transcript levels were significantly reduced by drought. CONCLUSIONS This study provides significant clues for research on roles of CsTCPs in regulating citrus plant growth and development, as well as responding to abiotic stresses.

Abstract
Bioinformatic analysis of moso bamboo TEOSINTE BRANCHED 1, CYCLOIDEA, and PROLIFERATING CELL FACTORS (TCP) transcription factors reveals their conservation and variation as well as the probable biological functions in abiotic stress response. Overexpressing PheTCP9 in Arabidopsis thaliana illustrates it may exhibit a new vision in different aspects of response to salt stress. Plant specific TCPs play important roles in plant growth, development and stress response, but studies of TCP in moso bamboo are limited. Therefore, in this study, a total of 40 TCP genes (PheTCP1 ~ 40) were identified and characterized from moso bamboo genome and divided into three different subfamilies, namely, 7 in TEOSINTE BRANCHED 1 / CYCLOIDEA (TB1/CYC), 14 in CINCINNATA (CIN) and 19 in PROLIFERATING CELL FACTOR (PCF). Subsequently, we analyzed the gene structures and conserved domain of these genes and found that the members from the same subfamilies exhibited similar exon/intron distribution patterns. Selection pressure and gene duplication analysis results indicated that PheTCP genes underwent strong purification selection during evolution. There were many cis-elements related to phytohermone and stress responsive existing in the upstream promoter regions of PheTCP genes, such as ABRE, CGTCA-motif and ARE. Subcellular localization experiments showed that PheTCP9 was a nuclear localized protein. As shown by β-glucuronidase (GUS) activity, the promoter of PheTCP9 was significantly indicated by salt stress. PheTCP9 was significantly induced in the roots, stems and leaves of moso bamboo. It was also significantly induced by NaCl solution. Overexpressing PheTCP9 increased the salt tolerance of transgenic Arabidopsis. Meanwhile, H2O2 and malondialdehyde (MDA) contents were significantly lower in PheTCP9 over expression (OE) transgenic Arabidopsis than WT. Catalase (CAT) activity, K+/Na+ ratio as well as CAT2 expression level was also much improved in transgenic Arabidopsis than WT under salt conditions. In addition, PheTCP9 OE transgenic Arabidopsis held higher survival rates of seedlings than WT under NaCl conditions. These results showed the positive regulation functions of PheTCP9 in plants under salt conditions.

The branchless gene Clbl in watermelon encoding a TERMINAL FLOWER 1 protein regulates the number of lateral branches. TAG. THEORETICAL AND APPLIED GENETICS. THEORETISCHE UND ANGEWANDTE GENETIK 2022; 135:65-79.

Abstract
A SNP mutation in Clbl gene encoding TERMINAL FLOWER 1 protein is responsible for watermelon branchless. Lateral branching is one of the most important traits, which directly determines plant architecture and crop productivity. Commercial watermelon has the characteristics of multiple lateral branches, and it is time-consuming and labor-costing to manually remove the lateral branches in traditional watermelon cultivation. In our present study, a lateral branchless trait was identified in watermelon material WCZ, and genetic analysis revealed that it was controlled by a single recessive gene, which named as Clbl (Citrullus lanatus branchless). A bulked segregant sequencing (BSA-seq) and linkage analysis was conducted to primarily map Clbl on watermelon chromosome 4. Next-generation sequencing-aided marker discovery and a large mapping population consisting of 1406 F2 plants were used to further map Clbl locus into a 9011-bp candidate region, which harbored only one candidate gene Cla018392 encoding a TERMINAL FLOWER 1 protein. Sequence comparison of Cla018392 between two parental lines revealed that there was a SNP detected from C to A in the coding region in the branchless inbred line WCZ, which resulted in a mutation from alanine (GCA) to glutamate (GAA) at the fourth exon. A dCAPS marker was developed from the SNP locus, which was co-segregated with the branchless phenotype in both BC1 and F2 population, and it was further validated in 152 natural watermelon accessions. qRT-PCR and in situ hybridization showed that the expression level of Cla018392 was significantly reduced in the axillary bud and apical bud in branchless line WCZ. Ectopic expression of ClTFL1 in Arabidopsis showed an increased number of lateral branches. The results of this study will be helpful for better understanding the molecular mechanism of lateral branch development in watermelon and for the development of marker-assisted selection (MAS) for new branchless watermelon cultivars.

Abstract
Ophiorrhiza pumila (O. pumila; Op) is a medicinal herbaceous plant, which can accumulate camptothecin (CPT). CPT and its derivatives are widely used as chemotherapeutic drugs for treating malignant tumors. Its biosynthesis pathway has been attracted significant attention. Teosinte branched 1/cycloidea/proliferating cell factors 1/2 (TCP) transcription factors (TFs) regulate a variety of physiological processes, while TCP TFs are involved in the regulation of CPT biosynthesis remain unclear. In this study, a systematic analysis of the TCP TFs family in O. pumila was performed. A total of 16 O. pumila TCP (OpTCP) genes were identified and categorized into two subgroups based on their phylogenetic relationships with those in Arabidopsis thaliana. Tissue-specific expression patterns revealed that nine OpTCP genes showed the highest expression levels in leaves, while the other seven OpTCPs showed a higher expression level in the stems. Co-expression, phylogeny analysis, and dual-luciferase (Dual-LUC) assay revealed that OpTCP15 potentially plays important role in CPT and its precursor biosynthesis. In addition, the subcellular localization experiment of candidate OpTCP genes showed that they are all localized in the nucleus. Our study lays a foundation for further functional characterization of the candidate OpTCP genes involved in CPT biosynthesis regulation and provides new strategies for increasing CPT production.

Abstract
Teosinte branched1/cycloidea/proliferating cell factor (TCP) gene family members are plant-specific transcription factors that regulate plant growth and development by controlling cell proliferation and differentiation. However, there are no reported studies on the TCP gene family in Dendrobium catenatum Lindl. Here, a genome-wide analysis of TCP genes was performed in D. catenatum, and 25 TCP genes were identified. A phylogenetic analysis classified the family into two clades: Class I and Class II. Genes in the same clade share similar conserved motifs. The GFP signals of the DcaTCP-GFPs were detected in the nuclei of tobacco leaf epidermal cells. The activity of DcaTCP4, which contains the miR319a-binding sequence, was reduced when combined with miR319a. A transient activity assay revealed antagonistic functions of Class I and Class II of the TCP proteins in controlling leaf development through the jasmonate-signaling pathway. After different phytohormone treatments, the DcaTCP genes showed varied expression patterns. In particular, DcaTCP4 and DcaTCP9 showed opposite trends after 3 h treatment with jasmonate. This comprehensive analysis provides a foundation for further studies on the roles of TCP genes in D. catenatum.

Abstract
Plant-specific TCP transcription factors play vital roles in the controlling of growth, development, and the stress response processes. Extensive researches have been carried out in numerous species, however, there hasn't been any information available about TCP genes in sweet potato (Ipomoea batatas L.). In this study, a genome-wide analysis of TCP genes was carried out to explore the evolution and function in sweet potato. Altogether, 18 IbTCPs were identified and cloned. The expression profiles of the IbTCPs differed dramatically in different organs or different stages of leaf development. Furthermore, four CIN-clade IbTCP genes contained miR319-binding sites. Blocking IbmiR319 significantly increased the expression level of IbTCP11/17 and resulted in a decreased photosynthetic rate due to the change in leaf submicroscopic structure, indicating the significance of IbmiR319-targeted IbTCPs in leaf anatomical morphology. A systematic analyzation on the characterization of the IbTCPs together with the primary functions in leaf anatomical morphology were conducted to afford a basis for further study of the IbmiR319/IbTCP module in association with leaf anatomical morphology in sweet potato.

Abstract
TEOSINTE BRANCHED1/CYCLOIDEA/PCF (TCP) family genes, as plant-specific transcription factors, play vital roles in flower pattern, leaf development and plant architecture. Our recent study shows that the TCP gene BRANCHED1 (CsBRC1) specifically regulates shoot branching in cucumber. Here, we found CsBRC1 had a closely related paralogous gene CsBRC1-like. The synteny analysis revealed that these two genes originated from a segmental duplication. CsBRC1-like displayed different expression patterns in cucumber compared with CsBRC1, indicating that they may have functional differentiation. Ectopic expression of CsBRC1-like in Arabidopsis brc1-1 mutant resulted in reduced rosette branches and rosette leaves, whereas silencing CsBRC1-like in cucumber only led to a deformed true leaf of seedling rather than affecting the shoot branching. RNA-seq analysis of wild-type and CsBRC1-like-RNAi plants implicated that CsBRC1-like might regulate early leaf development through affecting the transcripts of auxin and cytokinin related genes in cucumber. Moreover, CsBRC1-like directly interacts with CsTCP10a and CsBRC1 in vivo. Our results demonstrated that CsBRC1-like has a specific role in regulating leaf development, and CsBRC1-like and CsBRC1 may have overlapping roles in shoot branching.

Abstract
Glandless cotton can be grown to obtain cotton seeds free of toxic gossypol for use as both food and feed. However, they are not grown normally due to their lesser productivity and higher susceptibility to biotic stress. Great attention has been paid to biotic stresses rather than abiotic stresses on glandless cotton. Chromium (Cr) is a common pollutant of soil and considered a serious threat to plants due to its adverse effects on different functions. Although numerous studies are available on the toxicity of Cr6+ in various plants. However, its adverse effects and mechanism of toxicity in glandless cotton can seldom be found in the literature. This study examined the Cr6+ effect on glandless cotton in comparison to glanded cotton. Four pairs of glanded and glandless cotton near-isogenic lines (NILs) were exposed to different doses (0, 10, 50, and 100 μM/L) of Cr6+ for seven days, and biochemical, physiological, molecular, and ultrastructure changes were observed, which were significantly affected by Cr6+ at high concentrations in all NILs. The effect of Cr6+ on ionic contents shows the same trend in glanded and glandless NILs except for manganese (Mn2+) that show inhibition in glandless (ZMS-12w and Coker-312w) and enhance in the glanded NIL (ZMS-17). The gene expression of superoxide dismutase (SOD) and peroxidase (POD) revealed similar trends as enzyme activities in glandless NILs. The principal component analysis (PCA) and Agglomerative hierarchical clustering (AHC) results of all NILs from morpho-physiological traits, cluster ZMS-16, and ZMS-17 into Cr6+ sensitive group. While the glandless NILs have the potential to cope with the Cr toxicity by increasing the antioxidant enzyme activity and their gene expression. This study also revealed that Cr6+ tolerance in cotton is genotypic and has an independent mechanism in the root that not related to low gossypol.

Abstract
The plant-specific TCP family proteins play an important role in the processes of plant growth and development. Broussonetia papyrifera is a versatile perennial deciduous tree, and its genome data have been published. However, no comprehensive analysis of the TCP gene family in B. papyrifera has been undertaken. In this study, 20 BpTCP genes (BpTCPs) were identified in the B. papyrifera genome. Phylogenetic analysis divided BpTCPs into three subclades, the PCF subclade, the CIN subclade and the CYC/TB1 subclade. Gene structure analysis displayed that all BpTCPs except BpTCP19 contained one coding region. Conserved motif analysis showed that BpTCP proteins in the same subclade possessed similar motif structures. Segmental duplication was the primary driving force for the expansion of BpTCPs. Expression patterns showed that BpTCPs may play diverse biological functions in organ or tissue development. Transcriptional activation activity analysis of BpTCP8, BpTCP14 and BpTCP19 showed that they possessed transcriptional activation ability. The ectopic expression analysis in Arabidopsis wild-type and AtBRC1 ortholog mutant showed that BpTCP8, BpTCP14 and BpTCP19 could prevent rosette branch outgrowth. Collectively, our study not only established the first genome-wide analysis of the B. papyrifera TCP gene family, but also provided valuable information for understanding the function of BpTCPs in shoot branching.

Abstract
The plant-specific TCP transcription factors are well-characterized in both monocots and dicots, which have been implicated in multiple aspects of plant biological processes such as leaf morphogenesis and senescence, lateral branching, flower development and hormone crosstalk. However, no systematic analysis of the petunia TCP gene family has been described. In this work, a total of 66 petunia TCP genes (32 PaTCP genes in P. axillaris and 34 PiTCP genes in P. inflata) were identified. Subsequently, a systematic analysis of 32 PaTCP genes was performed. The phylogenetic analysis combined with structural analysis clearly distinguished the 32 PaTCP proteins into two classes—class Ι and class Ⅱ. Class Ⅱ was further divided into two subclades, namely, the CIN-TCP subclade and the CYC/TB1 subclade. Plenty of cis-acting elements responsible for plant growth and development, phytohormone and/or stress responses were identified in the promoter of PaTCPs. Distinct spatial expression patterns were determined among PaTCP genes, suggesting that these genes may have diverse regulatory roles in plant growth development. Furthermore, differential temporal expression patterns were observed between the large- and small-flowered petunia lines for most PaTCP genes, suggesting that these genes are likely to be related to petal development and/or petal size in petunia. The spatiotemporal expression profiles and promoter analysis of PaTCPs indicated that these genes play important roles in petunia diverse developmental processes that may work via multiple hormone pathways. Moreover, three PaTCP-YFP fusion proteins were detected in nuclei through subcellular localization analysis. This is the first comprehensive analysis of the petunia TCP gene family on a genome-wide scale, which provides the basis for further functional characterization of this gene family in petunia.

Abstract
Background Teosinte branched1/Cycloidea/proliferating cell factors (TCPs) are plant-specific transcription factors widely involved in leaf development, flowering, shoot branching, the circadian rhythm, hormone signaling, and stress responses. However, the TCP function in Brassica juncea var. tumida, the tumorous stem mustard, has not yet been reported. This study identified and characterized the entire TCP family members in B. juncea var. tumida. Methods We identified 62 BjTCP genes from the B. juncea var. tumida genome and analyzed their phylogenetic relationship, gene structure, protein motifs, chromosome location, and expression profile in different tissues. Results Of the 62 BjTCP genes we identified in B. juncea var. tumida, containing 34 class I and 28 class II subfamily members, 61 were distributed on 18 chromosomes. Gene structure and conserved motif analysis showed that the same clade genes displayed a similar exon/intron gene structure and conserved motifs. Cis-acting element results showed that the same clade genes also had a similar cis-acting element; however, subtle differences implied a different regulatory pathway. The BjTCP18s members were low-expressed in Dayejie strains and the unswelling stage of Yonganxiaoye strains. Treatment with gibberellin (GA) and salicylic acid (SA) showed that GA and SA affect the expression levels of multiple TCP genes. Conclusion We performed the first genome-wide analysis of the TCP gene family of B. juncea var. tumida. Our results have provided valuable information for understanding the classification and functions of TCP genes in B. juncea var. tumida.

Abstract
The TEOSINTE BRANCHED 1/CYCLOIDEA/PROLIFERATING CELL FACTORS (TCP) protein, belonging to a plant-specific transcription factors (TFs) family, participates in the control of plant growth and development by regulating cell proliferation. Until now, a comprehensive study of concerning the TCP gene family and their roles in grapevine (Vitis vinifera L.) has not been completed. Using bioinformatics approaches, 17 VvTCP genes were identified and further classified into two classes, designated class I (PCF subclass) and class II (CIN and CYC/TB1 subclass), which was further supported by exon-intron organizations and conserved motif analysis. Promoter analysis demonstrated that VvTCPs have numerous cis-acting elements related to plant growth and development, phytohormone, and abiotic/biotic stress responses. The singleton duplication of grapevine TCP genes contributed to this gene family expansion. The syntenic analyses among Vitis vinifera, Arabidopsis, and Oryza sativa showed that these genes located in corresponding syntenic blocks arose before the divergence of V. vinifera, Arabidopsis, and O. sativa. The expression levels of 17 VvTCPs were determined in different tissues and fruit developmental stages, and abscisic acid (ABA) treatment. Seventeen VvTCPs exhibited distinct tissue-specific expression patterns, potentially illustrating the functional divergence of VvTCPs in all tested tissues. Eleven VvTCPs were down-regulated in five berry developmental stages, while three VvTCPs were up-regulated. Additionally, many members were strongly modulated by ABA treatment, suggesting these VvTCPs have important and diverse regulatory roles in ABA treatment. Our results provide valuable information on the evolution and functions of the VvTCPs, pave the way for further functional verification of these VvTCPs in grapevine.

Abstract
The 'neglected' thermophile fruit crop of watermelon was first used as a model crop to study the PCD associated with anther dehiscence in cold-exposed condition during anther development. Anther dehiscence ensures normal pollen release and successful fertilization at fruit-setting stages in flowering plants. However, most researches pertinent to anther dehiscence are centered on model plant and/or major field crops under optimal growth condition. Due to anther indehiscence in cold condition, crop plants of thermophile tropical or subtropical fruit crops fail to accomplish timely pollination and fertilization, resulting in a great yield loss annually. Herein, we developed an ideal model crop for studying the programmed cell death (PCD) associated with anther dehiscence under low-temperature stress using the S-shaped spiral anther in watermelon as instead. Our results revealed that, including the tapetal cell layers, both cells of the interlocular septum and the stomium were blocked in PCD associated with anther dehiscence at 15 °C. Likewise, TUNEL assays visualized the evidence that low temperature at 15 °C interferes with not only the PCD of tapetal cells, but also the PCD of interlocular septum and stomium. Furthermore, the expressions of genes correlated with PCD of tapetum and stomium were significantly inhibited at 15 °C, suggesting that low temperature affects anther dehiscence by inhibiting PCD of sporophytic tissue-related gene expressions. The findings of the current research provide mechanistic insights into anther indehiscence leading to poor fruit-setting for thermophile fruit crop such as watermelon under adverse cold condition in flowering.

Abstract
The plant-specific Teosinte-branched 1/Cycloidea/Proliferating (TCP) transcription factor genes are involved in plants' development, hormonal pathways, and stress response but their evolutionary history is uncertain. The genome-wide analysis performed here for 47 plant species revealed 535 TCP candidates in terrestrial plants and none in aquatic plants, and that TCP family genes originated early in the history of land plants. Phylogenetic analysis divided the candidate genes into Classes I and II, and Class II was further divided into CYCLOIDEA (CYC) and CINCINNATA (CIN) clades; CYC is more recent and originated from CIN in angiosperms. Protein architecture, intron pattern, and sequence characteristics were conserved in each class or clade supporting this classification. The two classes significantly expanded through whole-genome duplication during evolution. Expression analysis revealed the conserved expression of TCP genes from lower to higher plants. The expression patterns of Class I and CIN genes in different stages of the same tissue revealed their function in plant development and their opposite effects in the same biological process. Interaction network analysis showed that TCP proteins tend to form protein complexes, and their interaction networks were conserved during evolution. These results contribute to further functional studies on TCP family genes.

Abstract
The TEOSINTE BRANCHED 1, CYCLOIDEA, and PROLIFERATING CELL FACTORS (TCP) gene family is a group of plant-specific transcription factors that have versatile functions in developmental processes and stress responses. In this study, a total of 73 TCP genes in upland cotton were identified and characterizated. Phylogenetic analysis classified them into three subgroups: 50 belonged to PCF, 16 to CIN, and 7 to CYC/TB1. GhTCP genes are randomly distributed in 22 of the 26 chromosomes in cotton. Expression patterns of GhTCPs were analyzed in 10 tissues, including different developmental stages of ovule and fiber, as well as under heat, salt, and drought stresses. Transcriptome analysis showed that 44 GhTCP genes exhibited varied transcript accumulation patterns in the tested tissues and 41 GhTCP genes were differentially expressed in response to heat, salt, and drought stresses. Furthermore, three GhTCP genes of the CIN clade were found to contain miR319-binding sites. An anti-correlation expression of GhTCP21 and GhTCP54 was analyzed with miR319 under salt and drought stress. Our results lay the foundation for understanding the complex mechanisms of GhTCP-mediated developmental processes and abiotic stress-signaling transduction pathways in cotton.

Abstract
TEOSINTE BRANCHED 1, CYCLOIDEA, and PROLIFERATING CELL FACTORS (T), members of a plant-specific gene family, play significant roles during plant growth and development, as well as in response to environmental stress. However, knowledge about this family in moso bamboo (Phyllostachys edulis) is limited. Therefore, in this study, the first genome-wide identification, classification, characterization, and expression pattern analysis of the TCP transcription factor family in moso bamboo was performed. Sixteen TCP members were identified from the moso bamboo genome using a BLASTP algorithm-based method and verified using the Pfam database. Based on a multiple-sequence alignment, the members were divided into two subfamilies, and members of the same family shared highly conserved motif structures. Subcellular localization and transactivation activity analyses of four selected genes revealed that they were nuclear localized and had self-activation activities. Additionally, the expression levels of several PeTCP members were significantly upregulated under abscisic acid, methyl jasmonate, and salicylic acid treatments, indicating that they play crucial plant hormone transduction roles in the processes of plant growth and development, as well as in responses to environmental stresses. Thus, the current study provides previously lacking information on the TCP family in moso bamboo and reveals the potential functions of this gene family in growth and development.

Global transcriptome and weighted gene co-expression network analyses reveal hybrid-specific modules and candidate genes related to plant height development in maize. PLANT MOLECULAR BIOLOGY 2018; 98:187-203.

Abstract
Weighted gene co-expression network analysis was explored to find key hub genes involved in plant height regulation. Plant height, an important trait for maize breeding because of its close relatedness to lodging resistance and yield, has been reported to be determined by multiple qualitative and quantitative genes. However, few genes related to plant height have been characterized in maize. Herein, three different maize hybrids, with extremely distinct plant height, which were further classified into low (L), middle (M) and high (H) group, were selected for RNA sequencing at three key developmental stages, namely, jointing stage (I), big flare period (II) and tasseling stage (III). Intriguingly, transcriptome profiles for hybrids ranging from low to high group exhibited significantly similarity in both jointing stage and big flare period. However, remarkably larger differentially expressed genes could be detected between hybrid from low to either middle or high group in tasseling stage. These results were repeatedly observed in both phenotyping and gene ontology enrichment analysis, indicating that transition from big flare period to tasseling stage plays a critical role in determination of plant height. Furthermore, weighted gene co-expression network analysis was explored to find key hub genes involved in plant height regulation. Hundreds of candidate genes, encoding various transcription factors, and regulators involved in internode cell regulation and cell wall synthesis were identified in our network. More importantly, great majority of candidates were correlated to either metabolism or signaling pathway of several plant phytohormones. Particularly, numerous functionally characterized genes in gibberellic acid as well as brassinosteroids signaling transduction pathways were also discovered, suggesting their critical roles in plant height regulation. The present study could provide a modestly comprehensive insight into networks for regulation of plant height in maize.

Abstract
Sea-island cotton (Gossypium barbadense) has drawn great attention in the textile industry for its comprehensive resistance and superior fiber properties. However, the mechanisms involved in fiber growth and development are unclear. As TCP transcription factors play important roles in plant growth and development, this study investigated the TCP family genes in G. barbadense (GbTCP). We identified 75 GbTCP genes, of which 68 had no introns. Phylogenetic analyses categorized the GbTCP transcription factors into 11 groups. Genomic analyses showed that 66 genes are located on 21 chromosomes. Phylogenetic analyses of G. arboreum, G. raimondii, G. hirsutum, G. barbadense, Theobroma cacao, Arabidopsis thaliana, Oryza sativa, Sorghum bicolor, and Zea mays, Picea abies, Sphagnum fallax and Physcomitrella patens, categorized 373 TCP genes into two classes (Classes I and II). By studying the structures of TCP genes in sea-island cotton, we identified genes from the same evolutionary branches that showed similar motif patterns. qRT-PCR results suggested that the GbTCPs had different expression patterns in fibers at various developmental stages of cotton, with several showing specific expression patterns during development. This report helps lay the foundation for future investigations of TCP functions and molecular mechanisms in sea-island cotton fiber development.

BIOCHIMICA ET BIOPHYSICA ACTA. GENE REGULATORY MECHANISMS 2018; 1861:613-622. [PMID: 29935343 DOI: 10.1016/j.bbagrm.2018.06.005] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/20/2018] [Revised: 06/10/2018] [Accepted: 06/11/2018] [Indexed: 12/14/2022]
Abstract
The biological processes involved in banana fruit ripening are extremely complex and modulated by a number of genes such as transcription factors (TFs). Although TFs like MADS, ERF and NAC are implicated in controlling banana ripening, little is known about other TFs such as TCP in this process. In this work, 25 MaTCPs named MaTCP1 to MaTCP25 were characterized from our previously reported transcriptomes related to banana ripening. Expression analysis revealed that these MaTCPs displayed differential expression patterns during the progression of banana ripening. Particularly, MaTCP5, MaTCP19 and MaTCP20 were ethylene-inducible and nuclear-localized, with MaTCP5 and MaTCP20 acting as transcriptional activators while MaTCP19 being a transcriptional inhibitor. Moreover, MaTCP5 and MaTCP20 promoted the transcription of MaXTH10/11 that may play a role in fruit softening during banana ripening, whereas MaTCP19 repressed their transcription, by directly binding to their promoters. Importantly, protein-protein interaction assays demonstrated that MaTCP20 physically interacts with MaTCP5 and MaTCP19 to form heterodimers in vitro and in vivo, and these protein complexes affects their transcriptional activities in regulating the target genes. Taken together, our results provide an overview of the interactions between MaTCPs in controlling the ripening-associated genes and lay a foundation for further investigation of MaTCP gene family in regulating banana fruit ripening.

Genome-Wide Identification of TCP Family Transcription Factors in Medicago truncatula Reveals Significant Roles of miR319-Targeted TCPs in Nodule Development. FRONTIERS IN PLANT SCIENCE 2018; 9:774.

Abstract
TCP proteins, the plant-specific transcription factors, are involved in the regulation of multiple aspects of plant development among different species, such as leaf development, branching, and flower symmetry. However, thus far, the roles of TCPs in legume, especially in nodulation are still not clear. In this study, a genome-wide analysis of TCP genes was carried out to discover their evolution and function in Medicago truncatula. In total, 21 MtTCPs were identified and classified into class I and class II, and the class II MtTCPs were further divided into two subclasses, CIN and CYC/TB1. The expression profiles of MtTCPs are dramatically different. The universal expression of class I MtTCPs was detected in all organs. However, the MtTCPs in CIN subclass were highly expressed in leaf and most of the members in CYC/TB1 subclass were highly expressed in flower. Such organ-specific expression patterns of MtTCPs suggest their different roles in plant development. In addition, most MtTCPs were down-regulated during the nodule development, except for the putative MtmiR319 targets, MtTCP3, MtTCP4, and MtTCP10A. Overexpression of MtmiR319A significantly reduced the expression level of MtTCP3/4/10A/10B and resulted in the decreased nodule number, indicating the important roles of MtmiR319-targeted MtTCPs in nodulation. Taken together, this study systematically analyzes the MtTCP gene family at a genome-wide level and their possible functions in nodulation, which lay the basis for further explorations of MtmiR319/MtTCPs module in association with nodule development in M. truncatula.

Abstract
TEOSINTE-BRANCHED1/CYCLOIDEA/PCF (TCP) transcription factors, a family of plant-specific proteins, play crucial roles in plant growth and development and stress response. However, systematical information is unknown regarding the TCP gene family in soybean. In the present study, a total of 54 GmTCPs were identified in soybean, which were grouped into 11 groups with the typical TCP conserved domains. Phylogenetic relationship, protein motif and gene structure analyses distinguished the GmTCPs into two homology classes: Class I and Class II. Class II was then differentiated into two subclasses: CIN and CYC/TB1. Unique cis-element number and composition existed in the promoter regions which might be involved in the gene transcriptional regulation of different GmTCPs. Tissue expression analysis demonstrated the diverse spatiotemporal expression profiles of GmTCPs. Furthermore, the interaction protein of one previously functionally unknown TCP protein-GmTCP8 was investigated. Yeast two-hybrid assay showed the interaction between GmTCP8 and an abscisic acid receptor (GmPYL10). QRT-PCR assays indicated the distinct expression profiles of GmTCPs in response to abiotic stresses (heat, drought and salt) and stress-related signals (abscisic acid, brassinolide, salicylicacid and methyl jasmonate). These results will facilitate to uncover the possible roles of GmTCPs under abiotic stress and hormone signal responses in soybean.

Abstract
TEOSINTE-BRANCHED1/CYCLOIDEA/PCF (TCP) proteins are important regulators of growth and developmental processes including branching, floral organ morphogenesis and leaf growth as well as stress response. This study identified 27 TCP genes of Phaseolus vulgaris (common bean), which were divided into three clusters based on phylogenetic relationship. In addition, this study showed that some of TCP genes such as Pvul-TCP-4 and Pvul-TCP-15 located on chromosomes 3 and 7, Pvul-TCP-7 and Pvul-TCP-20 located on chromosome 7 and 9, were segmentally duplicated. On the other hand, a total of 20 Pvul-TCP genes have predicted to be targeted by microRNAs (miRNA). Most of the miRNA-target genes were Pvul-TCP-1, -11, -13 and -27, which were targeted by 13, 17, 22 and 13 plant miRNAs, respectively. miR319 was one of the highly represented regulatory miRNAs to target TCP transcripts. Promoter region analysis of TCP genes resulted that the GT-1 motif, which was related to salt stress, was found in 14 different Pvul-TCP genes. Expression profiling of 10 Pvul-TCP genes based on RNA-sequencing data further confirmed with quantitative real-time RT-PCR measurements identified that Pvul-TCP genes under salt stress are expressed in a cultivar- and tissue-specific manner.

Abstract
The TCP transcription factors usually act as integrators of multiple growth regulatory and environmental stimuli. However, little is known about this gene family in the important tropical crop cassava (Manihot esculenta). In this study, 36 TCP genes were identified and renamed based on cassava whole-genome sequence and their sequence similarity with Arabidopsis TCPs. Typical TCP domains were detected in these proteins by multiple sequence alignment analysis. Evolutionary analysis indicated that MeTCPs could be divided into 8 subgroups, which was further supported by gene structure and conserved motif analyses. qRT-PCR analysis revealed tissue-specific and hormone-responsive expression patterns of MeTCP genes. Moreover, with global expression and promoter analysis, we found that MeTCPs showed similar or distinct expression patterns under cold and/or drought stress, suggesting that they might participate in distinct signaling pathways. Our study provides the first comprehensive analysis of TCP gene family in the cassava genome. The data will be useful for uncovering the potential functions of MeTCP genes, and their possible roles in mediating hormone and abiotic stress responses in cassava.

Abstract
Background Cucurbita pepo is a cucurbit with growing economic importance worldwide. Zucchini morphotype is the most important within this highly variable species. Recently, transcriptome and Simple Sequence Repeat (SSR)- and Single Nucleotide Polymorphism (SNP)-based medium density maps have been reported, however further genomic tools are needed for efficient molecular breeding in the species. Our objective is to combine currently available complete transcriptomes and the Zucchini genome sequence with high throughput genotyping methods, mapping population development and extensive phenotyping to facilitate the advance of genomic research in this species. Results We report the Genotyping-by-sequencing analysis of a RIL population developed from the inter subspecific cross Zucchini x Scallop (ssp. pepo x ssp. ovifera). Several thousands of SNP markers were identified and genotyped, followed by the construction of a high-density linkage map based on 7,718 SNPs (average of 386 markers/linkage group) covering 2,817.6 cM of the whole genome, which is a great improvement with respect to previous maps. A QTL analysis was performed using phenotypic data obtained from the RIL population from three environments. In total, 48 consistent QTLs for vine, flowering and fruit quality traits were detected on the basis of a multiple-environment analysis, distributed in 33 independent positions in 15 LGs, and each QTL explained 1.5–62.9% of the phenotypic variance. Eight major QTLs, which could explain greater than 20% of the phenotypic variation were detected and the underlying candidate genes identified. Conclusions Here we report the first SNP saturated map in the species, anchored to the physical map. Additionally, several consistent QTLs related to early flowering, fruit shape and length, and rind and flesh color are reported as well as candidate genes for them. This information will enhance molecular breeding in C. pepo and will assist the gene cloning underlying the studied QTLs, helping to reveal the genetic basis of the studied processes in squash.

Abstract
CYCLOIDEA-like genes are involved in the symmetry gene network, limiting cell proliferation in the dorsal regions of bilateral flowers in core eudicots. CYC-like and closely related TCP genes (acronym for TEOSINTE BRANCHED1, CYCLOIDEA, and PROLIFERATION CELL FACTOR) have been poorly studied in Asparagales, the largest order of monocots that includes both bilateral flowers in Orchidaceae (ca. 25.000 spp) and radially symmetrical flowers in Hypoxidaceae (ca. 200 spp). With the aim of assessing TCP gene evolution in the Asparagales, we isolated TCP-like genes from publicly available databases and our own transcriptomes of Cattleya trianae (Orchidaceae) and Hypoxis decumbens (Hypoxidaceae). Our matrix contains 452 sequences representing the three major clades of TCP genes. Besides the previously identified CYC specific core eudicot duplications, our ML phylogenetic analyses recovered an early CIN-like duplication predating all angiosperms, two CIN-like Asparagales-specific duplications and a duplication prior to the diversification of Orchidoideae and Epidendroideae. In addition, we provide evidence of at least three duplications of PCF-like genes in Asparagales. While CIN-like and PCF-like genes have multiplied in Asparagales, likely enhancing the genetic network for cell proliferation, CYC-like genes remain as single, shorter copies with low expression. Homogeneous expression of CYC-like genes in the labellum as well as the lateral petals suggests little contribution to the bilateral perianth in C. trianae. CIN-like and PCF-like gene expression suggests conserved roles in cell proliferation in leaves, sepals and petals, carpels, ovules and fruits in Asparagales by comparison with previously reported functions in core eudicots and monocots. This is the first large scale analysis of TCP-like genes in Asparagales that will serve as a platform for in-depth functional studies in emerging model monocots.

Abstract
The teosinte branched1/cycloidea/proliferating cell factor (TCP) gene family is a plant-specific transcription factor that participates in the control of plant development by regulating cell proliferation. However, no report is currently available about this gene family in turnips (Brassica rapa ssp. rapa). In this study, a genome-wide analysis of TCP genes was performed in turnips. Thirty-nine TCP genes in turnip genome were identified and distributed on 10 chromosomes. Phylogenetic analysis clearly showed that the family was classified as two clades: class I and class II. Gene structure and conserved motif analysis showed that the same clade genes have similar gene structures and conserved motifs. The expression profiles of 39 TCP genes were determined through quantitative real-time PCR. Most CIN-type BrrTCP genes were highly expressed in leaf. The members of CYC/TB1 subclade are highly expressed in flower bud and weakly expressed in root. By contrast, class I clade showed more widespread but less tissue-specific expression patterns. Yeast two-hybrid data show that BrrTCP proteins preferentially formed heterodimers. The function of BrrTCP2 was confirmed through ectopic expression of BrrTCP2 in wild-type and loss-of-function ortholog mutant of Arabidopsis. Overexpression of BrrTCP2 in wild-type Arabidopsis resulted in the diminished leaf size. Overexpression of BrrTCP2 in triple mutants of tcp2/4/10 restored the leaf phenotype of tcp2/4/10 to the phenotype of wild type. The comprehensive analysis of turnip TCP gene family provided the foundation to further study the roles of TCP genes in turnips.

Abstract
Plant-specific TEOSINTE BRANCHED 1, CYCLOIDEA, and PROLIFERATING CELL FACTORS (TCP) transcription factors play versatile functions in multiple processes of plant growth and development. However, no systematic study has been performed in strawberry. In this study, 19 FvTCP genes were identified in the diploid woodland strawberry (Fragaria vesca) accession Heilongjiang-3. Phylogenetic analysis suggested that the FvTCP genes were classified into two main classes, with the second class further divided into two subclasses, which was supported by the exon-intron organizations and the conserved motif structures. Promoter analysis revealed various cis-acting elements related to growth and development, hormone and/or stress responses. We analyzed FvTCP gene transcript accumulation patterns in different tissues and fruit developmental stages. Among them, 12 FvTCP genes exhibited distinct tissue-specific transcript accumulation patterns. Eleven FvTCP genes were down-regulated in different fruit developmental stages, while five FvTCP genes were up-regulated. Transcripts of FvTCP genes also varied with different subcultural propagation periods and were induced by hormone treatments and biotic and abiotic stresses. Subcellular localization analysis showed that six FvTCP-GFP fusion proteins showed distinct localizations in Arabidopsis mesophyll protoplasts. Notably, transient over-expression of FvTCP9 in strawberry fruits dramatically affected the expression of a series of genes implicated in fruit development and ripening. Taken together, the present study may provide the basis for functional studies to reveal the role of this gene family in strawberry growth and development.
