Genome of the early spider-orchid Ophrys sphegodes provides insights into sexual deception and pollinator adaptation. Nat Commun 2024; 15:6308. [PMID: 39060266 PMCID: PMC11282089 DOI: 10.1038/s41467-024-50622-4] [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: 11/06/2023] [Accepted: 07/17/2024] [Indexed: 07/28/2024] Open
Abstract
Pollinator-driven evolution of floral traits is thought to be a major driver of angiosperm speciation and diversification. Ophrys orchids mimic female insects to lure male pollinators into pseudocopulation. This strategy, called sexual deception, is species-specific, thereby providing strong premating reproductive isolation. Identifying the genomic architecture underlying pollinator adaptation and speciation may shed light on the mechanisms of angiosperm diversification. Here, we report the 5.2 Gb chromosome-scale genome sequence of Ophrys sphegodes. We find evidence for transposable element expansion that preceded the radiation of the O. sphegodes group, and for gene duplication having contributed to the evolution of chemical mimicry. We report a highly differentiated genomic candidate region for pollinator-mediated evolution on chromosome 2. The Ophrys genome will prove useful for investigations into the repeated evolution of sexual deception, pollinator adaptation and the genomic architectures that facilitate evolutionary radiations.

[PMID: 38902627 PMCID: PMC11191298 DOI: 10.1186/s12870-024-05047-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Accepted: 04/19/2024] [Indexed: 06/22/2024]
Abstract
BACKGROUND The plant-specific YABBY transcription factor family plays important roles in plant growth and development, particularly leaf growth, floral organ formation, and secondary metabolite synthesis. RESULTS Here, we identified a total of 13 OfYABBY genes from the Osmanthus fragrans genome. These 13 OfYABBY genes were divided into five subfamilies through phylogenetic analysis, and genes in the same subfamily showed similar gene structures and conserved protein motifs. Gene duplication promoted the expansion of the OfYABBY family in O. fragrans. Tissue-specific expression analysis showed that the OfYABBY family was mainly expressed in O. fragrans leaves and floral organs. To better understand the role of OfYABBY genes in plant growth and development, OfYABBY12 was selected for heterologous stable overexpression in tobacco, and OfYABBY12-overexpressing tobacco leaves released significantly fewer volatile organic compounds than wild-type tobacco leaves. Overexpression of OfYABBY12 led to the downregulation of NtCCD1/4 and decreased β-ionone biosynthesis. Correspondingly, a dual-luciferase assay showed that OfYABBY12 negatively regulated the expression of OfCCD4, which promotes β-ionone synthesis. Furthermore, tobacco leaves overexpressing OfYABBY12 were curled and wrinkled and had significantly reduced leaf thickness and leaf inclusions and significantly extended flower pistils (styles). CONCLUSION Overall, the results suggest that the OfYABBY gene family may influence the biosynthesis of the floral scent (especially β-ionone) in O. fragrans and may regulate leaf morphogenesis and lateral organs.

Abstract
The plant-specific transcription factor gene family, YABBY, plays an important role in plant development and stress response. Although YABBY genes have been identified in numerous species, a comprehensive characterization of YABBYs in tea tree and oil tea has been lacking. In this study, ten and three YABBY genes were identified in Camellia sinensis and C. oleifera, respectively. YABBY proteins could be divided into five subfamilies. Most YABBY genes in the same clade had similar structures and conserved motifs. Protein evolutionary analysis revealed that FIL/YAB3 displayed high conservation in all positions, followed by INO, YAB2, YAB5, and CRC. Specific site analysis suggested that the YABBY family was polyphyletic during the evolution. Compared to C. oleifera, two segmentally duplicated gene pairs were formed in C. sinensis during recent WGD events generated 30.69 and 45.08 Mya, respectively. Cis-acting element indicated that most YABBY genes contain box4, ARE, and MYB elements. A total of 120 SSR loci were found within CsYABBYs, consisting of six types, while 48 SSR loci were identified within CoYABBY, consisting of three types. Transcriptome results revealed that CRC and INO clades were specifically expressed in floral organs. The expression of CsYABBY10 and CsYABBY5 was significantly up-regulated under drought and salt treatments, respectively, as confirmed by qRT-PCR. CoYABBY genes were more susceptible to salt stress, as CoYABBY3 increased by about 15-fold. Furthermore, functional differentiation may have occurred in duplicated genes. These discoveries provide important information for further research on YABBYs in tea tree and oil tea.

Genome-wide analysis of the switchgrass YABBY family and functional characterization of PvYABBY14 in response to ABA and GA stress in Arabidopsis. BMC PLANT BIOLOGY 2024; 24:114. [PMID: 38365570 PMCID: PMC10870668 DOI: 10.1186/s12870-024-04781-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Accepted: 01/29/2024] [Indexed: 02/18/2024]
Abstract
BACKGROUND The small YABBY plant-specific transcription factor has a prominent role in regulating plant growth progress and responding to abiotic stress. RESULTS Here, a total of 16 PvYABBYs from switchgrass (Panicum virgatum L.) were identified and classified into four distinct subgroups. Proteins within the same subgroup exhibited similar conserved motifs and gene structures. Synteny analyses indicated that segmental duplication contributed to the expansion of the YABBY gene family in switchgrass and that complex duplication events occurred in rice, maize, soybean, and sorghum. Promoter regions of PvYABBY genes contained numerous cis-elements related to stress responsiveness and plant hormones. Expression profile analysis indicated higher expression levels of many PvYABBY genes during inflorescence development and seed maturation, with lower expression levels during root growth. Real-time quantitative PCR analysis demonstrated the sensitivity of multiple YABBY genes to PEG, NaCl, ABA, and GA treatments. The overexpression of PvYABBY14 in Arabidopsis resulted in increased root length after treatment with GA and ABA compared to wild-type plants. CONCLUSIONS Taken together, our study provides the first genome-wide overview of the YABBY transcription factor family, laying the groundwork for understanding the molecular basis and regulatory mechanisms of PvYABBY14 in response to ABA and GA responses in switchgrass.

Genome-Wide Identification of the YABBY Gene Family in Dendrobium Orchids and Its Expression Patterns in Dendrobium chrysotoxum. Int J Mol Sci 2023; 24:10165. [PMID: 37373311 DOI: 10.3390/ijms241210165] [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: 05/25/2023] [Revised: 06/10/2023] [Accepted: 06/12/2023] [Indexed: 06/29/2023] Open
Abstract
The small plant-specific YABBY gene family plays key roles in diverse developmental processes in plants. Dendrobium chrysotoxum, D. huoshanense, and D. nobile are perennial herbaceous plants belonging to Orchidaceae with a high ornamental value. However, the relationships and specific functions of the YABBY genes in the Dendrobium species remain unknown. In this study, six DchYABBYs, nine DhuYABBYs, and nine DnoYABBYs were identified from the genome databases of the three Dendrobium species, which were unevenly distributed on five, eight, and nine chromosomes, respectively. The 24 YABBY genes were classified into four subfamilies (CRC/DL, INO, YAB2, and FIL/YAB3) based on their phylogenetic analysis. A sequence analysis showed that most of the YABBY proteins contained conserved C2C2 zinc-finger and YABBY domains, while a gene structure analysis revealed that 46% of the total YABBY genes contained seven exons and six introns. All the YABBY genes harbored a large number of Methyl Jasmonate responsive elements, as well as anaerobic induction cis-acting elements in the promoter regions. Through a collinearity analysis, one, two, and two segmental duplicated gene pairs were identified in the D. chrysotoxum, D. huoshanense, and D. nobile genomes, respectively. The Ka/Ks values of these five gene pairs were lower than 0.5, indicating that the Dendrobium YABBY genes underwent negative selection. In addition, an expression analysis revealed that DchYABBY2 plays a role in ovary and early-stage petal development, while DchYABBY5 is essential for lip development and DchYABBY6 is crucial for early sepal formation. DchYABBY1 primarily regulates sepals during blooming. Furthermore, there is the potential involvement of DchYABBY2 and DchYABBY5 in gynostemium development. The results of a comprehensive genome-wide study would provide significant clues for future functional investigations and pattern analyses of YABBY genes in different flower parts during flower development in the Dendrobium species.

Abstract
YABBY is among the specific transcription factor (TF) gene family in plants and plays an important role in the development of the leaves and floral organs. Its specific roles include lateral organ development, the establishment of dorsoventral polarity, and response to abiotic stress. Potato is an important crop worldwide and YABBY genes are not still identified and characterized in potato. So, little has been known about YABBY genes in potato until now. This study was carried out to perform genome-wide analysis, which will provide an in-depth analysis about the role of YABBY genes in potato. There have been seven StYAB genes identified, which are found to be located on seven different chromosomes. Through multiple sequence analyses, it has been predicted that the YABBY domain was present in all seven genes while the C2-C2 domain was found to be absent only in StYAB2. With the help of cis-element analysis, the involvement of StYAB genes in light, stress developmental, and hormonal responsiveness has been found. Furthermore, expression analysis from RNA-seq data of different potato organs indicated that all StYAB genes have a role in the vegetative growth of the potato plant. In addition to this, RNA-seq data also identified StYAB3, StYAB5, and StYAB7 genes showing expression during cadmium, and drought stress, while StYAB6 was highly expressed during a viral attack. Moreover, during the attack of Phytophthora infestans on a potato plant StYAB3, StYAB5, StYAB6, and StYAB7 showed high expression. This study provides significant knowledge about the StYAB gene structures and functions, which can later be used for gene cloning, and functional analysis; this information may be utilized by molecular biologists and plant breeders for the development of new potato lines.

Abstract
These YABBY genes are transcription factors (TFs) that play crucial roles in various developmental processes in plants. There is no comprehensive characterization of YABBY genes in a valuable Chinese orchid herb, Dendrobium officinale. In this study, a total of nine YABBY genes were identified in the D. officinale genome. These YABBY genes were divided into four subfamilies: CRC/DL, FIL, INO, and YAB2. Expression pattern analyses showed that eight of the YABBY genes were strongly expressed in reproductive organs (flower buds) but weakly expressed in vegetative organs (roots, leaves, and stems). DoYAB1, DoYAB5, DoDL1, and DoDL3 were abundant in the small flower bud stage, while DoDL2 showed no changes throughout flower development. In addition, DoDL1-3 genes were strongly expressed in the column, tenfold more than in sepals, petals, and the lip. DoYAB1 from the FIL subfamily, DoYAB2 from the YAB2 subfamily, DoYAB3 from the INO subfamily, and DoDL2 and DoDL3 from the CRC/DL subfamily were selected for further analyses. Subcellular localization analysis showed that DoYAB1-3, DoDL2, and DoDL3 were localized in the nucleus. DoYAB2 and DoYAB3 interacted strongly with DoWOX2 and DoWOX4, while DoYAB1 showed a weak interaction with DoWOX4. These results reveal a regulatory network involving YABBY and WOX proteins in D. officinale. Our data provide clues to understanding the role of YABBY genes in the regulation of flower development in this orchid and shed additional light on the function of YABBY genes in plants.

Abstract
As plant-specific transcription regulators, YABBYs are involved in plant growth, development and stress responses. However, little information is available about genome-wide screening and identification of OsYABBY-interacting proteins. In this study, phylogenetic relationship, gene structure, protein structure and gene expression profile of eight OsYABBYs were carried out, all of which indicated that OsYABBYs were involved in different developmental processes and had functional differentiation. More importantly, PPI (protein-protein interaction) analysis and molecular docking simulation predicted that WUSCHEL-related homeobox (WOX) proteins might be interacting proteins of OsYABBYs. Yeast two-hybrid (Y2H) and luciferase complementation imaging assays (LCI) further confirmed that OsYABBYs (except for OsYABBY7) could interact with OsWOX3A in vitro and in vivo. In addition, OsYABBY3 and OsYABBY5 also could interact with OsWUS. Taken together, our results provided valuable information for further elucidating OsYABBYs regulation mechanism in improving rice performance.

Abstract
TCP gene family are specific transcription factors for plant, and considered to play an important role in development and growth. However, few related studies investigated the TCP gene trait and how it plays a role in growth and development of Orchidaceae. In this study, we obtained 14 TCP genes (CgTCPs) from the Spring Orchid Cymbidium goeringii genome. The classification results showed that 14 CgTCPs were mainly divided into two clades as follows: four PCF genes (Class I), nine CIN genes and one CYC gene (Class II). The sequence analysis showed that the TCP proteins of C. goeringii contain four conserved regions (basic Helix-Loop-Helix) in the TCP domain. The exon-intron structure varied in the clade according to a comparative investigation of the gene structure, and some genes had no introns. There are fewer CgTCP homologous gene pairs compared with Dendrobium catenatum and Phalaenopsis equestris, suggesting that the TCP genes in C. goeringii suffered more loss events. The majority of the cis-elements revealed to be enriched in the function of light responsiveness, followed by MeJA and ABA responsiveness, demonstrating their functions in regulating by light and phytohormones. The collinearity study revealed that the TCPs in D. catenatum, P. equestris and C. goeringii almost 1:1. The transcriptomic data and real-time reverse transcription-quantitative PCR (RT-qPCR) expression profiles showed that the flower-specific expression of the TCP class II genes (CgCIN2, CgCIN5 and CgCIN6) may be related to the regulation of florescence. Altogether, this study provides a comprehensive analysis uncovering the underlying function of TCP genes in Orchidaceae.

Abstract
Members of the YABBY gene family play significant roles in lamina development in cotyledons, floral organs, and other lateral organs. The Orchidaceae family is one of the largest angiosperm groups. Some YABBYs have been reported in Orchidaceae. However, the function of YABBY genes in Cymbidium is currently unknown. In this study, 24 YABBY genes were identified in Cymbidium ensifolium, C. goeringii, and C. sinense. We analyzed the conserved domains and motifs, the phylogenetic relationships, chromosome distribution, collinear correlation, and cis-elements of these three species. We also analyzed expression patterns of C. ensifolium and C. goeringii. Phylogenetic relationships analysis indicated that 24 YABBY genes were clustered in four groups, INO, CRC/DL, YAB2, and YAB3/FIL. For most YABBY genes, the zinc finger domain was located near the N-terminus and the helix-loop-helix domain (YABBY domain) near the C-terminus. Chromosomal location analysis results suggested that only C. goeringii YABBY has tandem repeat genes. Almost all the YABBY genes displayed corresponding one-to-one relationships in the syntenic relationships analysis. Cis-elements analysis indicated that most elements were clustered in light-responsive elements, followed by MeJA-responsive elements. Expression patterns showed that YAB2 genes have high expression in floral organs. RT-qPCR analysis showed high expression of CeYAB3 in lip, petal, and in the gynostemium. CeCRC and CeYAB2.2 were highly expressed in gynostemium. These findings provide valuable information of YABBY genes in Cymbidium species and the function in Orchidaceae.

Abstract
Orchidaceae is one of the largest, most diverse families in angiosperms with significant ecological and economical values. Orchids have long fascinated scientists by their complex life histories, exquisite floral morphology and pollination syndromes that exhibit exclusive specializations, more than any other plants on Earth. These intrinsic factors together with human influences also make it a keystone group in biodiversity conservation. The advent of sequencing technologies and transgenic techniques represents a quantum leap in orchid research, enabling molecular approaches to be employed to resolve the historically interesting puzzles in orchid basic and applied biology. To date, 16 different orchid genomes covering four subfamilies (Apostasioideae, Vanilloideae, Epidendroideae, and Orchidoideae) have been released. These genome projects have given rise to massive data that greatly empowers the studies pertaining to key innovations and evolutionary mechanisms for the breadth of orchid species. The extensive exploration of transcriptomics, comparative genomics, and recent advances in gene engineering have linked important traits of orchids with a multiplicity of gene families and their regulating networks, providing great potential for genetic enhancement and improvement. In this review, we summarize the progress and achievement in fundamental research and industrialized application of orchids with a particular focus on molecular tools, and make future prospects of orchid molecular breeding and post-genomic research, providing a comprehensive assemblage of state of the art knowledge in orchid research and industrialization.

Abstract
YABBY transcription factors (TFs) are plant-specific and are characterized by a C2-C2 zinc finger domain at the N-terminus and a YABBY domain at the C-terminus. In this study, eight YABBY genes were identified in the Brachypodium distachyon genome and were unevenly distributed across four chromosomes. Phylogenetic analysis classified BdYABBYs into FIL/YAB3, YAB2, CRC, and INO clades. Sixty-two putative cis-elements were identified in BdYABBY gene putative promoters, among them, CAAT-box, TATA-box, MYB, MYC, ARE, and Box_4 were shared by all. BdYABBY genes are highly expressed in inflorescences, and abiotic stresses regulate their expression. In addition, three transcripts of BdDL were identified. Over-expression in Arabidopsis has shown their different functions in reproductive development, as well as in response to cold stress. Our study lays the foundation for the functional elucidation of BdYABBY genes.

Abstract
Orchids are members of the Orchidaceae, one of the largest families of flowering plants, and occupy a wide range of ecological habitats with highly specialized reproductive features. They exhibit unique developmental characteristics, such as generation of storage organs during flowering and spectacular floral morphological features, which contribute to their reproductive success in different habitats in response to various environmental cues. Here we review current understanding of the molecular genetic basis of orchid reproductive development, including flowering time control, floral patterning and flower color, with a focus on the orchid genes that have been functionally validated in plants. Furthermore, we summarize recent progress in annotating orchid genomes, and discuss how integration of high-quality orchid genome sequences with other advanced tools, such as the ever-improving multi-omics approaches and genome editing technologies as well as orchid-specific technical platforms, could open up new avenues to elucidate the molecular genetic basis of highly specialized reproductive organs and strategies in orchids.

Abstract
Background Members of the plant-specific YABBY gene family are thought to play an important role in the development of leaf, flower, and fruit. The YABBY genes have been characterized and regarded as vital contributors to fruit development in Arabidopsis thaliana and tomato, in contrast to that in the important tropical economic fruit star fruit (Averrhoa carambola), even though its genome is available. Methods In the present study, a total of eight YABBY family genes (named from AcYABBY1 to AcYABBY8) were identified from the genome of star fruit, and their phylogenetic relationships, functional domains and motif compositions, physicochemical properties, chromosome locations, gene structures, protomer elements, collinear analysis, selective pressure, and expression profiles were further analyzed. Results Eight AcYABBY genes (AcYABBYs) were clustered into five clades and were distributed on five chromosomes, and all of them had undergone negative selection. Tandem and fragment duplications rather than WGD contributed to YABBY gene number in the star fruit. Expression profiles of AcYABBYs from different organs and developmental stages of fleshy fruit indicated that AcYABBY4 may play a specific role in regulating fruit size. These results emphasize the need for further studies on the functions of AcYABBYs in fruit development.

Abstract
The YABBY gene family is one of the plant transcription factors present in all seed plants. The family members were extensively studied in various plants and shown to play important roles in plant growth and development, such as the polarity establishment in lateral organs, the formation and development of leaves and flowers, and the response to internal plant hormone and external environmental stress signals. In this study, a total of 364 YABBY genes were identified from 37 Brassicaceae genomes, of which 15 were incomplete due to sequence gaps, and nine were imperfect (missing C2C2 zinc-finger or YABBY domain) due to sequence mutations. Phylogenetic analyses resolved these YABBY genes into six compact clades except for a YAB3-like gene identified in Aethionema arabicum. Seventeen Brassicaceae species each contained a complete set of six basic YABBY genes (i.e., 1 FIL, 1 YAB2, 1 YAB3, 1 YAB5, 1 INO and 1 CRC), while 20 others each contained a variable number of YABBY genes (5-25) caused mainly by whole-genome duplication/triplication followed by gene losses, and occasionally by tandem duplications. The fate of duplicate YABBY genes changed considerably according to plant species, as well as to YABBY gene type. These YABBY genes were shown to be syntenically conserved across most of the Brassicaceae species, but their functions might be considerably diverged between species, as well as between paralogous copies, as demonstrated by the promoter and expression analysis of YABBY genes in two Brassica species (B. rapa and B. oleracea). Our study provides valuable insights for understanding the evolutionary story of YABBY genes in Brassicaceae and for further functional characterization of each YABBY gene across the Brassicaceae species.

Extending the Toolkit for Beauty: Differential Co-Expression of DROOPING LEAF-Like and Class B MADS-Box Genes during Phalaenopsis Flower Development. Int J Mol Sci 2021; 22:ijms22137025.

Abstract
The molecular basis of orchid flower development is accomplished through a specific regulatory program in which the class B MADS-box AP3/DEF genes play a central role. In particular, the differential expression of four class B AP3/DEF genes is responsible for specification of organ identities in the orchid perianth. Other MADS-box genes (AGL6 and SEP-like) enrich the molecular program underpinning the orchid perianth development, resulting in the expansion of the original “orchid code” in an even more complex gene regulatory network. To identify candidates that could interact with the AP3/DEF genes in orchids, we conducted an in silico differential expression analysis in wild-type and peloric Phalaenopsis. The results suggest that a YABBY DL-like gene could be involved in the molecular program leading to the development of the orchid perianth, particularly the labellum. Two YABBY DL/CRC homologs are present in the genome of Phalaenopsis equestris, PeDL1 and PeDL2, and both express two alternative isoforms. Quantitative real-time PCR analyses revealed that both genes are expressed in column and ovary. In addition, PeDL2 is more strongly expressed the labellum than in the other tepals of wild-type flowers. This pattern is similar to that of the AP3/DEF genes PeMADS3/4 and opposite to that of PeMADS2/5. In peloric mutant Phalaenopsis, where labellum-like structures substitute the lateral inner tepals, PeDL2 is expressed at similar levels of the PeMADS2-5 genes, suggesting the involvement of PeDL2 in the development of the labellum, together with the PeMADS2-PeMADS5 genes. Although the yeast two-hybrid analysis did not reveal the ability of PeDL2 to bind the PeMADS2-PeMADS5 proteins directly, the existence of regulatory interactions is suggested by the presence of CArG-boxes and other MADS-box transcription factor binding sites within the putative promoter of the orchid DL2 gene.

Genome-Wide Analysis of the YABBY Transcription Factor Family in Rapeseed ( Brassica napus L.). Genes (Basel) 2021; 12:genes12070981.

Abstract
The YABBY family of plant-specific transcription factors play important regulatory roles during the development of leaves and floral organs, but their functions in Brassica species are incompletely understood. Here, we identified 79 YABBY genes from Arabidopsis thaliana and five Brassica species (B. rapa, B. nigra, B. oleracea, B. juncea, and B. napus). A phylogenetic analysis of YABBY proteins separated them into five clusters (YAB1–YAB5) with representatives from all five Brassica species, suggesting a high degree of conservation and similar functions within each subfamily. We determined the gene structure, chromosomal location, and expression patterns of the 21 BnaYAB genes identified, revealing extensive duplication events and gene loss following polyploidization. Changes in exon–intron structure during evolution may have driven differentiation in expression patterns and functions, combined with purifying selection, as evidenced by Ka/Ks values below 1. Based on transcriptome sequencing data, we selected nine genes with high expression at the flowering stage. qRT-PCR analysis further indicated that most BnaYAB family members are tissue-specific and exhibit different expression patterns in various tissues and organs of B. napus. This preliminary study of the characteristics of the YABBY gene family in the Brassica napus genome provides theoretical support and reference for the later functional identification of the family genes.

Abstract
Mounting evidence from genomic and transcriptomic studies suggests that most genetic networks regulating the morphogenesis of land plant sporophytes were co-opted and modified from those already present in streptophyte algae and gametophytes of bryophytes sensu lato. However, thus far, no candidate genes have been identified that could be responsible for "planation", a conversion from a three-dimensional to a two-dimensional growth pattern. According to the telome theory, "planation" was required for the genesis of the leaf blade in the course of leaf evolution. The key transcription factors responsible for leaf blade development in angiosperms are YABBY proteins, which until recently were thought to be unique for seed plants. Yet, identification of a YABBY homologue in a green alga and the recent findings of YABBY homologues in lycophytes and hornworts suggest that YABBY proteins were already present in the last common ancestor of land plants. Thus, these transcriptional factors could have been involved in "planation", which fosters our understanding of the origin of leaves. Here, we summarise the current data on functions of YABBY proteins in the vegetative and reproductive development of diverse angiosperms and gymnosperms as well as in the development of lycophytes. Furthermore, we discuss a putative role of YABBY proteins in the genesis of multicellular shoot apical meristems and in the evolution of leaves in early divergent terrestrial plants.

Genome-Wide Identification of the YABBY Gene Family in Seven Species of Magnoliids and Expression Analysis in Litsea. PLANTS (BASEL, SWITZERLAND) 2020; 10:E21. [PMID: 33374250 PMCID: PMC7824534 DOI: 10.3390/plants10010021] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 12/13/2020] [Accepted: 12/22/2020] [Indexed: 12/11/2022]
Abstract
The YABBY gene family, specific to seed plants, encodes a class of transcription factors in the lamina maintenance and development of lateral organs. Magnoliids are sisters to the clade-containing eudicots and monocots, which have rapidly diversified among the common ancestors of these three lineages. However, prior to this study, information on the function of the YABBY genes in magnoliids was extremely limited to the third major clades and the early diverging lineage of Mesangiospermae. In this study, the sum of 55 YABBY genes including five genes in INO, six in CRC, eight in YAB2, 22 in YAB5, and 14 in FIL clade were identified from seven magnoliid plants. Sequence analysis showed that all encoded YABBY protein sequences possess the highly conserved YABBY domain and C2C2 zinc-finger domain. Gene and protein structure analysis indicates that a certain number of exons were highly conserved and similar in the same class, and YABBY genes encode proteins of 71-392 amino acids and an open reading frame of 216-1179 bp in magnoliids. Additionally, the predicted molecular weight and isoelectric point of YABBY proteins in three species ranged from 7689.93 to 43578.13 and from 5.33 to 9.87, respectively. Meanwhile, the YABBY gene homolog expression of Litsea was detected at a temporal and spatial level during various developmental stages of leaf and reproductive tissues. This research could provide a brief overview of YABBY gene family evolution and its differential expression in magnoliids. Therefore, this comprehensive diversification analysis would provide a new insight into further understanding of the function of genes in seven magnoliids.
