Miao F, Chen W, Zhao Y, Zhao P, Sang X, Lu J, Wang H. The RING-Type E3 Ubiquitin Ligase Gene GhDIRP1 Negatively Regulates Verticillium dahliae Resistance in Cotton ( Gossypium hirsutum). PLANTS (BASEL, SWITZERLAND) 2024; 13:2047. [PMID: 39124165 DOI: 10.3390/plants13152047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/15/2024] [Revised: 07/21/2024] [Accepted: 07/23/2024] [Indexed: 08/12/2024]
Abstract
Cotton is one of the world's most important economic crops. Verticillium wilt is a devastating cotton disease caused by Verticillium dahliae, significantly impacting cotton yield and quality. E3 ubiquitin ligases are essential components of the ubiquitin-mediated 26S proteasome system, responsible for recognizing ubiquitinated target proteins and promoting their degradation, which play a crucial regulatory role in plant immune responses. In this study, on the basis of the confirmation of differential expression of GhDIRP1, a RING-type E3 ubiquitin ligase encoding gene, in two cotton varieties resistant (Zhongzhimian 2) or susceptible (Jimian 11) to V. dahliae, we demonstrated that GhDIRP1 is a negative regulator of V. dahliae resistance because silencing GhDIRP1 in cotton and heterogeneously overexpressing the gene in Arabidopsis enhanced and compromised resistance to V. dahliae, respectively. The GhDIRP1-mediated immune response seemed to be realized through multiple physiological pathways, including hormone signaling, reactive oxygen species, and lignin biosynthesis. Based on the sequences of GhDIRP1 isolated from Zhongzhimian 2 and Jimian 11, we found that GhDIRP1 had identical coding but different promoter sequences in the two varieties, with the promoter of Zhongzhimian 2 being more active than that of Jimian 11 because the former drove a stronger expression of GUS and LUC reporter genes. The results link the ubiquitination pathway to multiple physiological pathways acting in the cotton immune response and provide a candidate gene for breeding cotton varieties resistant to V. dahliae.

Int J Mol Sci 2024; 25:7696. [PMID: 39062941 PMCID: PMC11276883 DOI: 10.3390/ijms25147696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2024] [Revised: 07/07/2024] [Accepted: 07/11/2024] [Indexed: 07/28/2024] Open
Abstract
Wheat is one of the most important food crops globally, and understanding the regulation of grain size is crucial for wheat breeding to achieve a higher grain yield. MicroRNAs (miRNAs) play vital roles in plant growth and development. However, the miRNA-mediated mechanism underlying grain size regulation remains largely elusive in wheat. Here, we report the characterization and functional validation of a miRNA, TamiR397a, associated with grain size regulation in wheat. The function of three TaMIR397 homoeologs was determined through histochemical β-glucuronidase-dependent assay. MiRNA expression was detected using quantitative reverse transcription polymerase chain reaction (qRT-PCR), and the function of TamiR397a was validated through its transgenic overexpression and repression in wheat. It was found that TaMIR397-6A and TaMIR397-6B encode active TamiR397a. The expression profiling indicated that TamiR397a was differentially expressed in various tissues and gradually up-regulated during grain filling. The inhibition of TamiR397a perturbed grain development, leading to a decrease in grain size and weight. Conversely, the overexpression of TamiR397a resulted in increased grain size and weight by accelerating the grain filling process. Transcriptome analysis revealed that TamiR397a regulates a set of genes involved in hormone response, desiccation tolerance, regulation of cellular senescence, seed dormancy, and seed maturation biological processes, which are important for grain development. Among the down-regulated genes in the grains of the TamiR397a-overexpressing transgenic plants, 11 putative targets of the miRNA were identified. Taken together, our results demonstrate that TamiR397a is a positive regulator of grain size and weight, offering potential targets for breeding wheat with an increased grain yield.

A comprehensive review on Gossypium hirsutum resistance against cotton leaf curl virus. Front Genet 2024; 15:1306469. [PMID: 38440193 PMCID: PMC10909863 DOI: 10.3389/fgene.2024.1306469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 02/01/2024] [Indexed: 03/06/2024] Open
Abstract
Cotton (Gossypium hirsutum L.) is a significant fiber crop. Being a major contributor to the textile industry requires continuous care and attention. Cotton is subjected to various biotic and abiotic constraints. Among these, biotic factors including cotton leaf curl virus (CLCuV) are dominant. CLCuV is a notorious disease of cotton and is acquired, carried, and transmitted by the whitefly (Bemisia tabaci). A cotton plant affected with CLCuV may show a wide range of symptoms such as yellowing of leaves, thickening of veins, upward or downward curling, formation of enations, and stunted growth. Though there are many efforts to protect the crop from CLCuV, long-term results are not yet obtained as CLCuV strains are capable of mutating and overcoming plant resistance. However, systemic-induced resistance using a gene-based approach remained effective until new virulent strains of CLCuV (like Cotton Leaf Curl Burewala Virus and others) came into existence. Disease control by biological means and the development of CLCuV-resistant cotton varieties are in progress. In this review, we first discussed in detail the evolution of cotton and CLCuV strains, the transmission mechanism of CLCuV, the genetic architecture of CLCuV vectors, and the use of pathogen and nonpathogen-based approaches to control CLCuD. Next, we delineate the uses of cutting-edge technologies like genome editing (with a special focus on CRISPR-Cas), next-generation technologies, and their application in cotton genomics and speed breeding to develop CLCuD resistant cotton germplasm in a short time. Finally, we delve into the current obstacles related to cotton genome editing and explore forthcoming pathways for enhancing precision in genome editing through the utilization of advanced genome editing technologies. These endeavors aim to enhance cotton's resilience against CLCuD.

Abstract
The F-box gene family is one of the largest gene families in plants, and it plays a crucial role in regulating plant development, reproduction, cellular protein degradation, and response to biotic and abiotic stresses. Despite their significance, a comprehensive analysis of the F-box gene family in Liriodendron chinense and other magnoliaceae species has not been reported. In this study, we report for the first time the identification of 144 full-length F-box genes in L. chinense. Based on specific domains and phylogenetic analyses, these genes were divided into 10 distinct subfamilies. We further analyzed their gene structure, conserved domain and chromosome distribution, genome-wide replication events, and collinearity. Additionally, based on GO analysis, we found that F-box genes exhibit functional specificity, with a significant proportion of them being involved in protein binding (GO:0005515), suggesting that F-box genes may play an important role in gene regulation in L. chinense. Transcriptome data and q-PCR results also showed that F-box genes are involved in the development of multiple tissues in L. chinense, regulate the somatic embryogenesis of Liriodendron hybrids, and play a pivotal role in abiotic stress. Altogether, these findings provide a foundation for understanding the biological function of F-box genes in L. chinense and other plant species.

PLANT SCIENCE : AN INTERNATIONAL JOURNAL OF EXPERIMENTAL PLANT BIOLOGY 2024; 338:111899.

Abstract
An exposure to extremely saline conditions can lead to significant oxidative damage in plants. Flavonoids, which are potent antioxidants, are critical for the scavenging of reactive oxygen species caused by abiotic stress. In the present study, the cotton F-box gene GhFB15 was isolated and characterized. The expression of GhFB15 was rapidly induced by salt as well as by exogenous hormones (ETH, MeJA, ABA, and GA). An analysis of subcellular localization revealed GhFB15 is mainly distributed in nuclei. Overexpression of GhFB15 adversely affected the salt tolerance of transgenic Arabidopsis plants as evidenced by decreased seed germination and seedling growth, whereas the silencing of GhFB15 improved the salt tolerance of cotton plants. Furthermore, we analyzed the gene expression profiles of VIGS-GhFB15 and TRV:00 plants. Many of the differentially expressed genes were associated with the flavonoid biosynthesis pathway. Moreover, lower flavonoid contents and higher levels of H2O2 and O2- were observed in the transgenic Arabidopsis plants. Conversely, the VIGS-GhFB15 cotton plants had relatively higher flavonoid contents, but lower H2O2 and O2- levels. These results suggest that GhFB15 negatively regulates salt tolerance, and silencing GhFB15 results in increased flavonoid accumulation and improved ROS scavenging.

Abstract
The cell cycle controls division and proliferation of all eukaryotic cells and is tightly regulated at multiple checkpoints by complexes of core cell cycle proteins. Due to the difficulty in accessing female gametes and zygotes of flowering plants, little is known about the molecular mechanisms underlying embryogenesis initiation despite the crucial importance of this process for seed crops. In this study, we reveal three levels of factors involved in rice zygotic cell cycle control and characterize their functions and regulation. Protein-protein interaction studies, including within zygote cells, and in vitro biochemical analyses delineate a model of the zygotic cell cycle core complex for rice. In this model, CDKB1, a major regulator of plant mitosis, is a cyclin (CYCD5)-dependent kinase; its activity is coordinately inhibited by two cell cycle inhibitors, KRP4 and KRP5; and both KRPs are regulated via F-box protein 3 (FB3)-mediated proteolysis. Supporting their critical roles in controlling the rice zygotic cell cycle, mutations in KRP4, KRP5 and FB3 result in the compromised function of sperm cells and abnormal organization of female germ units, embryo and endosperm, thus significantly reducing seed-set rate. This work helps reveal regulatory mechanisms controlling the zygotic cell cycle toward seed formation in angiosperms.

Abstract
KEY MESSAGE F-box E3-ubiquitin ligases regulate critical biological processes in plant development and stress responses. Future research could elucidate why and how plants have acquired a large number of F-box genes. The ubiquitin-proteasome system (UPS) is a predominant regulatory mechanism employed by plants to maintain the protein turnover in the cells and involves the interplay of three classes of enzymes, E1 (ubiquitin-activating), E2 (ubiquitin-conjugating), and E3 ligases. The diverse and most prominent protein family among eukaryotes, F-box proteins, are a vital component of the multi-subunit SCF (Skp1-Cullin 1-F-box) complex among E3 ligases. Several F-box proteins with multifarious functions in different plant systems have evolved rapidly over time within closely related species, but only a small part has been characterized. We need to advance our understanding of substrate-recognition regulation and the involvement of F-box proteins in biological processes and environmental adaptation. This review presents a background of E3 ligases with particular emphasis on the F-box proteins, their structural assembly, and their mechanism of action during substrate recognition. We discuss how the F-box proteins regulate and participate in the signaling mechanisms of plant development and environmental responses. We highlight an urgent need for research on the molecular basis of the F-box E3-ubiquitin ligases in plant physiology, systems biology, and biotechnology. Further, the developments and outlooks of the potential technologies targeting the E3-ubiquitin ligases for developing crop improvement strategies have been discussed.

Int J Mol Sci 2023; 24:ijms24065652. [PMID: 36982726 PMCID: PMC10057536 DOI: 10.3390/ijms24065652] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 03/11/2023] [Accepted: 03/14/2023] [Indexed: 03/18/2023] Open
Abstract
The basic helix-loop-helix (bHLH) proteins compose one of the largest transcription factor (TF) families in plants, which play a vital role in regulating plant biological processes including growth and development, stress response, and secondary metabolite biosynthesis. Ipomoea aquatica is one of the most important nutrient-rich vegetables. Compared to the common green-stemmed I. aquatica, purple-stemmed I. aquatica has extremely high contents of anthocyanins. However, the information on bHLH genes in I. aquatica and their role in regulating anthocyanin accumulation is still unclear. In this study, we confirmed a total of 157 bHLH genes in the I. aquatica genome, which were classified into 23 subgroups according to their phylogenetic relationship with the bHLH of Arabidopsis thaliana (AtbHLH). Of these, 129 IabHLH genes were unevenly distributed across 15 chromosomes, while 28 IabHLH genes were spread on the scaffolds. Subcellular localization prediction revealed that most IabHLH proteins were localized in the nucleus, while some were in the chloroplast, extracellular space, and endomembrane system. Sequence analysis revealed conserved motif distribution and similar patterns of gene structure within IabHLH genes of the same subfamily. Analysis of gene duplication events indicated that DSD and WGD played a vital role in the IabHLH gene family expansion. Transcriptome analysis showed that the expression levels of 13 IabHLH genes were significantly different between the two varieties. Of these, the IabHLH027 had the highest expression fold change, and its expression level was dramatically higher in purple-stemmed I. aquatica than that in green-stemmed I. aquatica. All upregulated DEGs in purple-stemmed I. aquatica exhibited the same expression trends in both qRT-PCR and RNA-seq. Three downregulated genes including IabHLH142, IabHLH057, and IabHLH043 determined by RNA-seq had opposite expression trends of those detected by qRT-PCR. Analysis of the cis-acting elements in the promoter region of 13 differentially expressed genes indicated that light-responsive elements were the most, followed by phytohormone-responsive elements and stress-responsive elements, while plant growth and development-responsive elements were the least. Taken together, this work provides valuable clues for further exploring IabHLH function and facilitating the breeding of anthocyanin-rich functional varieties of I. aquatica.

Genome-Wide Analysis of the FBA Subfamily of the Poplar F-Box Gene Family and Its Role under Drought Stress. Int J Mol Sci 2023; 24:ijms24054823. [PMID: 36902250 PMCID: PMC10002531 DOI: 10.3390/ijms24054823] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 02/17/2023] [Accepted: 02/28/2023] [Indexed: 03/06/2023] Open
Abstract
F-box proteins are important components of eukaryotic SCF E3 ubiquitin ligase complexes, which specifically determine protein substrate proteasomal degradation during plant growth and development, as well as biotic and abiotic stress. It has been found that the FBA (F-box associated) protein family is one of the largest subgroups of the widely prevalent F-box family and plays significant roles in plant development and stress response. However, the FBA gene family in poplar has not been systematically studied to date. In this study, a total of 337 F-box candidate genes were discovered based on the fourth-generation genome resequencing of P. trichocarpa. The domain analysis and classification of candidate genes revealed that 74 of these candidate genes belong to the FBA protein family. The poplar F-box genes have undergone multiple gene replication events, particularly in the FBA subfamily, and their evolution can be attributed to genome-wide duplication (WGD) and tandem duplication (TD). In addition, we investigated the P. trichocarpa FBA subfamily using the PlantGenIE database and quantitative real-time PCR (qRT-PCR); the results showed that they are expressed in the cambium, phloem and mature tissues, but rarely expressed in young leaves and flowers. Moreover, they are also widely involved in the drought stress response. At last, we selected and cloned PtrFBA60 for physiological function analysis and found that it played an important role in coping with drought stress. Taken together, the family analysis of FBA genes in P. trichocarpa provides a new opportunity for the identification of P. trichocarpa candidate FBA genes and elucidation of their functions in growth, development and stress response, thus demonstrating their utility in the improvement of P. trichocarpa.

Quantitative trait locus mapping and identification of candidate genes for resistance to Verticillium wilt in four recombinant inbred line populations of Gossypium hirsutum. PLANT SCIENCE : AN INTERNATIONAL JOURNAL OF EXPERIMENTAL PLANT BIOLOGY 2023; 327:111562. [PMID: 36509244 DOI: 10.1016/j.plantsci.2022.111562] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Revised: 12/01/2022] [Accepted: 12/06/2022] [Indexed: 05/16/2023]
Abstract
Improving resistance to Verticillium wilt is of great significance for achieving high and stable yields of Upland cotton (Gossypium hirsutum). To deeply understand the genetic basis of cotton resistance to Verticillium wilt, Verticillium wilt-resistant Upland Lumianyan 28 and four Verticillium wilt-susceptible Acala cotton cultivars were used to create four recombinant inbred line (RIL) populations of 469 families through nested hybridization. Phenotypic data collected in five stressful environments were used to select resistant and sensitive lines and create a mixed pool of extreme phenotypes for BSA-seq. A total of 8 QTLs associated with Verticillium wilt resistance were identified on 4 chromosomes, of which qVW-A12-5 was detected simultaneously in the RIL populations and in one of the RIL populations and was identified for the first time. According to the sequence comparison and transcriptome analysis of candidate genes in the QTL interval between parents and pools, 4 genes were identified in the qVW-A12-5 interval. qRT-PCR of parental and phenotypically extreme lines revealed that Gh_CPR30 was induced by and may be a candidate gene for resistance to Verticillium wilt in G. hirsutum. Furthermore, VIGS technology revealed that the disease severity index (DSI) of the Gh_CPR30-silenced plants was significantly higher than that of the control. These results indicate that the Gh_CPR30 gene plays an important role in the resistance of G. hirsutum to Verticillium wilt, and the study provides a molecular basis for analyzing the molecular mechanism underlying G. hirsutum resistance to Verticillium wilt.

Abstract
F-box genes play an important role in plant growth and resistance to abiotic and biotic stresses. To date, systematic analysis of F-box genes and functional annotation in eggplant (Solanum melongena) is still limited. Here, we identified 389 F-box candidate genes in eggplant. The domain study of F-box candidate genes showed that the F-box domain is conserved, whereas the C-terminal domain is diverse. There are 376 SmFBX candidate genes distributed on 12 chromosomes. A collinearity analysis within the eggplant genome suggested that tandem duplication is the dominant form of F-box gene replication in eggplant. The collinearity analysis between eggplant and the three other species (Arabidopsis thaliana, rice and tomato) provides insight into the evolutionary characteristics of F-box candidate genes. In addition, we analyzed the expression of SmFBX candidate genes in different tissues under high temperature and bacterial wilt stress. The results identified several F-box candidate genes that potentially participate in eggplant heat tolerance and bacterial wilt resistance. Moreover, the yeast two-hybrid assay showed that several representative F-box candidate proteins interacted with representative Skp1 proteins. Overexpression of SmFBX131 and SmFBX230 in tobacco increased resistance to bacterial wilt. Overall, these results provide critical insights into the functional analysis of the F-box gene superfamily in eggplant and provide potentially valuable targets for heat and bacterial resistance.

Abstract
F-box/LR (FBXL), Leucine-rich repeats in F-box proteins, belongs to the Skp1-Cullin1-F-box protein (SCF) E3 ligase family. FBXL genes play important roles in plant growth, such as plant hormones, responses to environmental stress, and floral organ development. Here, a total of 518 FBXL genes were identified and analyzed in six plant species. Phylogenetic analysis showed that AtFBXLs, VvFBXLs, and GrFBXLs were clustered into three subfamilies (Ⅰ-Ⅲ). Based on the composition of the F-box domain and carboxyl-terminal amino acid sequence, FBXL proteins were classified into three types (Type-A/-B/-C). Whole-genome duplication (WGD) along with tandem duplications and segmental contributed to the expansion of this gene family. The result indicates that four cotton species are also divided into three subfamilies. FBXLs in cotton were classified into three clades by phylogenetic and structural analyses. Furthermore, expression analyses indicated that the expression patterns of GhFBXLs in different cotton tissues were different. The highly expressed of GH_A07G2363 in 5-8 mm anthers, indicates that this gene might play a role in the reproductive process, providing candidate genes for future studies on cotton fertility materials. This study provides an original functional opinion and a useful interpretation of the FBXL protein family in cotton.

Soybean F-Box-Like Protein GmFBL144 Interacts With Small Heat Shock Protein and Negatively Regulates Plant Drought Stress Tolerance. FRONTIERS IN PLANT SCIENCE 2022; 13:823529.

Abstract
The F-box gene family is one of the largest gene families in plants. These genes regulate plant growth and development, as well as biotic and abiotic stress responses, and they have been extensively researched. Drought stress is one of the major factors limiting the yield and quality of soybean. In this study, bioinformatics analysis of the soybean F-box gene family was performed, and the role of soybean F-box-like gene GmFBL144 in drought stress adaptation was characterized. We identified 507 F-box genes in the soybean genome database, which were classified into 11 subfamilies. The expression profiles showed that GmFBL144 was highly expressed in plant roots. Overexpression of GmFBL144 increased the sensitivity of transgenic Arabidopsis to drought stress. Under drought stress, the hydrogen peroxide (H2O2) and malonaldehyde (MDA) contents of transgenic Arabidopsis were higher than those of the wild type (WT) and empty vector control, and the chlorophyll content was lower than that of the control. Y2H and bimolecular fluorescence complementation (BiFC) assays showed that GmFBL144 can interact with GmsHSP. Furthermore, our results showed that GmFBL144 can form SCF FBL144 (E3 ubiquitin ligase) with GmSkp1 and GmCullin1. Altogether, these results indicate that the soybean F-box-like protein GmFBL144 may negatively regulate plant drought stress tolerance by interacting with sHSP. These findings provide a basis for molecular genetics and breeding of soybean.

Abstract
In this study, genome-wide characterization of F-box proteins in sweet potato yielded 243 IbFBX genes, unevenly distributed on the 15 chromosomes of sweet potato. Gene duplication analysis suggested segmental duplication as the principal factor influencing the expansive evolution of IbFBX genes in sweet potato. Phylogenetic analysis clustered F-box proteins in sweet potato, Arabidopsis, and rice into six clades (I-VI). Gene structure analysis of the IbFBX genes revealed that most of the genes within the same clade were highly conserved. Expression profiles of IbFBX family genes in 9 different tissues and under stress conditions revealed that the IbFBXs were highly upregulated or downregulated in response to salt and drought stress, suggesting their significant roles in abiotic stress response and adaptation. Knowledge of the diverse functions and expression patterns of IbFBXs presents a solid theoretical basis for annotating the functions of IbFBXs and further facilitate the molecular breeding of sweet potato.

Abstract
Fructose 1,6-bisphosphate aldolase (FBA) as a key enzyme play crucial roles in glycolysis, gluconeogenesis and Calvin cycle processes in plants. However, limited information is known regarding FBA genes in Nicotiana tabacum. In this study, 16 FBAs were identified and characterized in Nicotiana tabacum. Phylogenetic analysis revealed that these genes can be categorized as type I (NtFBA1-10 located in chloroplast) and type II (NtFBA11-16 located in cytoplasm) subfamilies. According to the conserved motifs and gene structure analysis, NtFBA protein sequences had the highly homologous to FBAs in other species. Most members of the NtFBA gene family responded positively to NaHCO3 stress, especially the expression of NtFBA13/14 increased by 642%. In addition, the expression results of NtFBAs under five abiotic stress (light, NaCl, NaHCO3, drought, and cold) conditions were showed that NtFBA13/14 were highly up-regulated. qRT-PCR results showed that most of the NtFBAs expressed higher in leaves. NtFBA7/8 and NtFBA13/14 have important significance in photosynthesis and abiotic stress, respectively. This study provides a basis foundation for further elucidating the function of NtFBAs and the N. tabacum mechanism of resistance under abiotic stress.

Abstract
BACKGROUND In plants, basic leucine zipper transcription factors (TFs) play important roles in multiple biological processes such as anthesis, fruit growth & development and stress responses. However, systematic investigation and characterization of bZIP-TFs remain unclear in Chinese white pear. Chinese white pear is a fruit crop that has important nutritional and medicinal values. RESULTS In this study, 62 bZIP genes were comprehensively identified from Chinese Pear, and 54 genes were distributed among 17 chromosomes. Frequent whole-genome duplication (WGD) and dispersed duplication (DSD) were the major driving forces underlying the bZIP gene family in Chinese white pear. bZIP-TFs are classified into 13 subfamilies according to the phylogenetic tree. Subsequently, purifying selection plays an important role in the evolution process of PbbZIPs. Synteny analysis of bZIP genes revealed that 196 orthologous gene pairs were identified between Pyrus bretschneideri, Fragaria vesca, Prunus mume, and Prunus persica. Moreover, cis-elements that respond to various stresses and hormones were found on the promoter regions of PbbZIP, which were induced by stimuli. Gene structure (intron/exon) and different compositions of motifs revealed that functional divergence among subfamilies. Expression pattern of PbbZIP genes differential expressed under hormonal treatment abscisic acid, salicylic acid, and methyl jasmonate in pear fruits by real-time qRT-PCR. CONCLUSIONS Collectively, a systematic analysis of gene structure, motif composition, subcellular localization, synteny analysis, and calculation of synonymous (Ks) and non-synonymous (Ka) was performed in Chinese white pear. Sixty-two bZIP-TFs in Chinese pear were identified, and their expression profiles were comprehensively analyzed under ABA, SA, and MeJa hormones, which respond to multiple abiotic stresses and fruit growth and development. PbbZIP gene occurred through Whole-genome duplication and dispersed duplication events. These results provide a basic framework for further elucidating the biological function characterizations under multiple developmental stages and abiotic stress responses.

Abstract
F-box genes are an integral component of the Skp1-cullin-F-box (SCF) complex in eukaryotes. These genes are primarily involved in determining substrate specificities during cellular proteolysis. Here we report that 410 members constitute the F-box superfamily in tomato. Based on the incidence of C-terminal domains, these genes fell into ten subfamilies, leucine-rich repeat domain-containing F-box members constituting the largest subfamily. The F-box genes are present on all 12 chromosomes with varying gene densities. Both segmental and tandem duplication events contribute significantly to their expansion in the tomato genome. The syntenic analysis revealed close relationships among F-box homologs within Solanaceae species genomes. Transcript profiling of F-box members identified several ripening-associated genes with altered expression in the ripening mutants. RNA-sequencing data analysis showed that phosphate (Pi) deficiency affected 55 F-box transcripts in the Pi-deficient seedlings compared to their control seedlings. The persistent up-regulation of eight members, including two phloem protein 2B (PP2-B) genes, PP2-B15, and MATERNAL EFFECT EMBRYO ARREST 66 (MEE66) homologs, at multiple time-points in the roots, shoot, and seedling, point towards their pivotal roles in Pi starvation response in tomato. The attenuation of such upregulation in sucrose absence revealed the necessity of this metabolite for robust activation of these genes in the Pi-deficient seedlings. Altogether, this study identifies novel F-box genes with potential roles in fruit ripening and Pi starvation response and unlocks new avenues for functional characterization of candidate genes in tomato and other related species.

The Landscape of the Genomic Distribution and the Expression of the F-Box Genes Unveil Genome Plasticity in Hexaploid Wheat during Grain Development and in Response to Heat and Drought Stress. Int J Mol Sci 2021; 22:ijms22063111. [PMID: 33803701 PMCID: PMC8002965 DOI: 10.3390/ijms22063111] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Revised: 03/01/2021] [Accepted: 03/15/2021] [Indexed: 11/17/2022] Open
Abstract
FBX proteins are subunits of the SCF complex (Skp1-cullin-FBX) belonging to the E3 ligase family, which is involved in the ubiquitin-proteasome 26S (UPS) pathway responsible for the post-translational protein turnover. By targeting, in a selective manner, key regulatory proteins for ubiquitination and 26S proteasome degradation, FBX proteins play a major role in plant responses to diverse developmental and stress conditions. Although studies on the genomic organization of the FBX gene family in various species have been reported, knowledge related to bread wheat (Triticum aestivum) is scarce and needs to be broadened. Using the latest assembly of the wheat genome, we identified 3670 TaFBX genes distributed non-homogeneously within the three subgenomes (A, B and D) and between the 21 chromosomes, establishing it as one of the richest gene families among plant species. Based on the presence of the five different chromosomal regions previously identified, the present study focused on the genomic distribution of the TaFBX family and the identification of differentially expressed genes during the embryogenesis stages and in response to heat and drought stress. Most of the time, when comparing the expected number of genes (taking into account the formal gene distribution on the entire wheat genome), the TaFBX family harbors a different pattern at the various stratum of observation (subgenome, chromosome, chromosomal regions). We report here that the local gene expansion of the TaFBX family must be the consequence of multiple and complex events, including tandem and small-scale duplications. Regarding the differentially expressed TaFBX genes, while the majority of the genes are localized in the distal chromosomal regions (R1 and R3), differentially expressed genes are more present in the interstitial regions (R2a and R2b) than expected, which could be an indication of the preservation of major genes in those specific chromosomal regions.

Abstract
Spodoptera litura is a major insect with a cosmopolitan distribution and strong resistance to multiple insecticides. Determining the molecular basis and key candidate genes of the insecticide resistance of S. litura may help in managing this insect. In this study, fifth-instar S. litura larvae were subjected to transcriptome analysis at 6, 12, 24, 48, and 72 h after feeding on an LC20 dose of avermectin. The result showed that genes responding to avermectin changed dynamically with different gene counts and resistance mechanisms at the fifth instar based on a metabolic pathway map. These responses included degrading the insecticide by a series of P450 and glutathione-S-transferase enzymes starting at the 12 h time point, with subsequent increases in the number of genes involved and shifts to TOLL and immune deficiency (IMD) pathways at 48 h after feeding the insecticide. Weighted correlation network analysis (WGCNA) determined a co-expression module related to the avermectin response at 12 and 24 h (r = 0.403, p = 0.0371; r = 0.436, p = 0.023), in which a hub gene (LOC111358940) related to metalloproteinase activity was identified. In addition, Analysis of the genes in the co-expression module further revealed that eight genes encoding UDP-glucuronosyltransferases were directly associated with insecticide response in S. litura. These results provide better understanding of the avermectin response mechanism of S. litura and may be useful in developing improved control strategies for this species.

Abstract
In plants, F-box proteins (FBPs) constitute one of the largest superfamilies of regulatory proteins. Most F-box proteins are shown to be an integral part of SCF complexes, which carry out the degradation of proteins and regulate diverse important biological processes. Anthers and pollen development have a huge importance in crop breeding. Despite the vast diversity of FBPs in Arabidopsis male reproductive organs, their role in anther and pollen development is not much explored. Moreover, a standard nomenclature for naming FBPs is also lacking. Here, we propose a standard nomenclature for naming the FBPs of Arabidopsis thaliana uniformly and carry out a systematic analysis of sperm cell-specific FBP gene, i.e., 3p.AtFBP113 due to its reported high and preferential expression, for detailed functional annotation. The results revealed that 3p.AtFBP113 is located on the small arm of chromosome and encodes 397 amino acid long soluble, stable, and hydrophilic protein with the possibility of localization in various cellular compartments. The presence of the C-terminal F-box associated domain (FBA) with immunoglobulin-like fold anticipated its role in protein binding. Gene ontology based functional annotation and tissue-specific gene co-expression analysis further strengthened its role in protein binding and ubiquitination. Moreover, various potential post/co-translational modifications were anticipated and the predicted tertiary structure also showed the presence of characteristic domains and fold. Thus, the outcomes of the study will be useful in developing a better understating of the function of 3p.AtFBP113 during the process of pollen development, which will be helpful for targeting the gene for manipulation of male fertility that has immense importance in hybrid breeding.

Characterization and Stress Response of the JmjC Domain-Containing Histone Demethylase Gene Family in the Allotetraploid Cotton Species Gossypium hirsutum. PLANTS 2020; 9:plants9111617. [PMID: 33233854 PMCID: PMC7709011 DOI: 10.3390/plants9111617] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Revised: 11/16/2020] [Accepted: 11/18/2020] [Indexed: 12/22/2022]
Abstract
Histone modification is an important epigenetic modification that controls gene transcriptional regulation in eukaryotes. Histone methylation is accomplished by histone methyltransferase and can occur on two amino acid residues, arginine and lysine. JumonjiC (JmjC) domain-containing histone demethylase regulates gene transcription and chromatin structure by changing the methylation state of the lysine residue site and plays an important role in plant growth and development. In this study, we carried out genome-wide identification and comprehensive analysis of JmjC genes in the allotetraploid cotton species Gossypium hirsutum. In total, 50 JmjC genes were identified and in G. hirsutum, and 25 JmjC genes were identified in its two diploid progenitors, G. arboreum and G. raimondii, respectively. Phylogenetic analysis divided these JmjC genes into five subfamilies. A collinearity analysis of the two subgenomes of G. hirsutum and the genomes of G. arboreum and G. raimondii uncovered a one-to-one relationship between homologous genes of the JmjC gene family. Most homologs in the JmjC gene family between A and D subgenomes of G. hirsutum have similar exon-intron structures, which indicated that JmjC family genes were conserved after the polyploidization. All G. hirsutumJmjC genes were found to have a typical JmjC domain, and some genes also possess other special domains important for their function. Analysis of promoter regions revealed that cis-acting elements, such as those related to hormone and abiotic stress response, were enriched in G. hirsutum JmjC genes. According to a reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis, most G. hirsutumJmjC genes had high abundance expression at developmental stages of fibers, suggesting that they might participate in cotton fiber development. In addition, some G. hirsutumJmjC genes were found to have different degrees of response to cold or osmotic stress, thus indicating their potential role in these types of abiotic stress response. Our results provide useful information for understanding the evolutionary history and biological function of JmjC genes in cotton.

Identification and expression analysis of some wheat F-box subfamilies during plant development and infection by Puccinia triticina. PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2020; 155:535-548. [PMID: 32836199 DOI: 10.1016/j.plaphy.2020.06.040] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Revised: 06/23/2020] [Accepted: 06/24/2020] [Indexed: 06/11/2023]
Abstract
As one of the largest protein families in plants, F-box proteins are involved in many important cellular processes. Until now, a limited number of investigations have been conducted on wheat F-box genes due to its variable structure and large and polyploid genome. Classification, identification, structural analysis, evolutionary relationship, and chromosomal distribution of some wheat F-box genes are described in the present study. A total number of 1013 potential F-box proteins which are encoded by 409 genes was identified in wheat, and classified into 12 subfamilies based on their C-terminal domain structures. Furthermore, proteins with identical or similar C-terminal domain were clustered together. Location of 409 F-box genes was identified on all 21 wheat chromosomes but showed an uneven distribution. Segmental duplication was the main reason for the increase in the number of wheat F-box genes. Gene expression analysis based on digital PCR showed that most of the F-box genes were highly expressed in the later development stages of wheat, including the formation of spike, grain, flag leaf, and participated in drought stress (DS), heat stress (HS), and their combination (HD). Of the nine F-box genes we investigated using quantitative PCR (qPCR) following fungal pathogen infection, five were involved in wheat resistance to the infection by leaf rust pathogen and one in the susceptible response. These results provide important information on wheat F-box proteins for further functional studies, especially the proteins that played roles in response to heat and drought stresses and leaf rust pathogen infection.
