Genome-Wide Identification and Characterization of TALE Superfamily Genes in Soybean (Glycine max L.).

ABSTRACT: The three-amino-acid-loop-extension (TALE) superfamily genes broadly existed in plants, which played important roles in plant growth, development and abiotic stress responses. In this study, we identified 68 Glycine max TALE (GmTALE) superfamily members. Phylogenetic analysis divided the GmTALE superfamily into the BEL1-like (BLH/BELL homeodomain) and the KNOX (KNOTTED-like homeodomain) subfamilies. Moreover, the KNOX subfamily could be further categorized into three clades (KNOX Class I, KNOX Class II and KNOX Class III). The GmTALE genes showed similarities in the gene structures in the same subfamily or clade, whose coding proteins exhibited analogous motif and conserved domain compositions. Besides, synteny analyses and evolutionary constraint evaluations of the TALE members among soybean and different species provided more clues for GmTALE superfamily evolution. The cis-element analyses in gene promoter regions and relevant gene expression profiling revealed different regulating roles of GmTALE genes during soybean plant development, saline and dehydration stresses. Genome-wide characterization, evolution, and expression profile analyses of GmTALE genes can pave the way for future gene functional research and facilitate their roles for applications in genetic improvement on soybean in saline and dehydration stresses.

Genome-wide identification and characterization of GRAS genes in soybean (Glycine max).

Project description:BACKGROUND:GRAS proteins are crucial transcription factors, which are plant-specific and participate in various plant biological processes. Thanks to the rapid progress of the whole genome sequencing technologies, the GRAS gene families in different plants have been broadly explored and studied. However, comprehensive research on the soybean (Glycine max) GRAS gene family is relatively lagging. RESULTS:In this study, 117 Glycine max GRAS genes (GmGRAS) were identified. Further phylogenetic analyses showed that the GmGRAS genes could be categorized into nine gene subfamilies: DELLA, HAM, LAS, LISCL, PAT1, SCL3, SCL4/7, SCR and SHR. Gene structure analyses turned out that the GmGRAS genes lacked introns and were relatively conserved. Conserved domains and motif patterns of the GmGRAS members in the same subfamily or clade exhibited similarities. Notably, the expansion of the GmGRAS gene family was driven both by gene tandem and segmental duplication events. Whereas, segmental duplications took the major role in generating new GmGRAS genes. Moreover, the synteny and evolutionary constraints analyses of the GRAS proteins among soybean and distinct species (two monocots and four dicots) provided more detailed evidence for GmGRAS gene evolution. Cis-element analyses indicated that the GmGRAS genes may be responsive to diverse environmental stresses and regulate distinct biological processes. Besides, the expression patterns of the GmGRAS genes were varied in various tissues, during saline and dehydration stresses and during seed germination processes. CONCLUSIONS:We conducted a systematic investigation of the GRAS genes in soybean, which may be valuable in paving the way for future GmGRAS gene studies and soybean breeding.

Genome-wide identification of PME genes, evolution and expression analyses in soybean (Glycine max L.).

Project description:BackgroundPectin methylesterase (PME) is one of pectin-modifying enzyme that affects the pectin homeostasis in cell wall and regulates plant growth and diverse biological processes. The PME genes have been well explored and characterized in different plants. Nevertheless, systematic research on the soybean (Glycine max L.) PME genes remain lacking.ResultsWe identified 127 Glycine max PME genes (GmPME) from the soybean Wm82.a2.v1 genome, which unevenly distributed on 20 soybean chromosomes. Phylogenetic analysis classified the GmPME genes into four clades (Group I, Group II, Group III and Group IV). GmPME gene members in the same clades displayed similar gene structures and motif patterns. The gene family expansion analysis demonstrated that segmental duplication was the major driving force to acquire novel GmPME genes compared to the tandem duplication events. Further synteny and evolution analyses showed that the GmPME gene family experienced strong purifying selective pressures during evolution. The cis-element analyses together with the expression patterns of the GmPME genes in various tissues suggested that the GmPME genes broadly participate in distinct biological processes and regulate soybean developments. Importantly, based on the transcriptome data and quantitative RT-PCR validations, we examined the potential roles of the GmPME genes in regulating soybean flower bud development and seed germination.ConclusionIn conclusion, we provided a comprehensive characterization of the PME genes in soybean, and our work laid a foundation for the functional study of GmPME genes in the future.

Gene-wide identification and expression analysis of the PMEI family genes in soybean (Glycine max).

Project description:Pectin Methylesterase Inhibitors (PMEI) gene family is widely spread in plants and plays crucial roles in plant development as well as biotic and abiotic stress response. However, little information was known about the function of PMEI genes in soybean. Herein, we identified 170 PMEI genes in soybean. These PMEI genes were divided into four groups (I-IV) based on phylogenetic analysis, and they were unevenly distributed in 18 soybean chromosomes. Gene structures and motif pattern analyses revealed that the PMEI genes in the same group showed the same characteristics. For the GmPMEI genes, gene duplication events occurred broadly, 52 pairs tandem duplication events and 55 pairs segmental duplication events suggested that the GmPMEI genes had high homology. Besides, the PMEI genes presented different expression patterns in different tissues, while several of these genes were expressed only in flowers. Under the biotic and abiotic stresses, PMEI genes had significant positive impact on the tolerance ability of soybean, and the ABA-responsive elements and SA-responsive elements played vital roles in responding to a variety of stresses. This study provides insights into the evolution and potential functions of GmPMEIs.

Genome-Wide Identification and Expression Analysis of <i>NRAMP</i> Family Genes in Soybean (<i>Glycine Max</i> L.).

Project description:The NRAMP (natural resistance-associated macrophage protein) family of genes has been widely characterized in organisms ranging from bacteria to yeast, plants, mice, and humans. This gene family plays vital roles in divalent metal ion transport across cellular membranes. As yet, comprehensive analysis of NRAMP family genes has not been reported for soybean. In this study, bioinformatics analysis was conducted to identify 13 soybean NRAMP genes, along with their gene structures, phylogenetic relationships, and transmembrane domains. Expression analysis suggests that GmNRAMP genes function in numerous tissues and development stages. Moreover, soybean NRAMP genes were differentially regulated by deficiencies of N, P, K, Fe, and S, along with toxicities of Fe, Cu, Cd, and Mn. These results indicate that GmNRAMP genes function in many nutrient stress pathways, and might be involved in crosstalk among nutrient stress pathways. Subcellular localization analysis in Arabidopsis protoplasts confirmed the tonoplast or plasma membrane localization of selected soybean NRMAP proteins. Protein-protein interaction analysis found that the networks of three GmNRAMP proteins which putatively interact with nodulin-like proteins, almost distinct from the network that is common to the other 10 soybean NRAMP proteins. Subsequent qRT-PCR results confirmed that these three GmNRMAP genes exhibited enhanced expression in soybean nodules, suggesting potential functions in the transport of Fe or other metal ions in soybean nodules. Overall, the systematic analysis of the GmNRAMP gene family reported herein provides valuable information for further studies on the biological roles of GmNRAMPs in divalent metal ion transport in various soybean tissues under numerous nutrient stresses and soybean-rhizobia symbiosis.

Genome-wide identification and expression analysis of the VQ gene family in soybean (Glycine max).

Project description:Background:VQ proteins, the plant-specific transcription factors, are involved in plant development and multiple stresses; however, only few articles systematic reported the VQ genes in soybean. Methods:In total, we identified 75 GmVQ genes, which were classified into 7 groups (I-VII). Conserved domain analysis indicated that VQ gene family members all contain the VQ domains. VQ genes from the same evolutionary branches of soybean shared similar motifs and structures. Promoter analysis revealed that cis-elements related to stress responses, phytohormone responses and controlling physical as well as reproductive growth. Based on the RNA-seq and qRT-PCR analysis, GmVQ genes were showed expressing in nine tissues, suggesting their putative function in many aspects of plant growth and development as well as response to stress in Glycine max. Results:This study aims to understand the roles of VQ genes in various development processes and their expression patterns in responses to stimuli. Our results provide basic information in identification and classification of GmVQ genes. Further experimental analysis will allows us to know the functions of GmVQs participation in plant growth and stress responses.

Genome-wide identification and localization of chalcone synthase family in soybean (Glycine max [L]Merr).

Project description:BackgroundSoybean is a paleopolyploid that has undergone two whole genome duplication events. Gene duplication is a type of genomic change that can lead to novel functions of pre-existing genes. Chalcone synthase (CHS) is the plant-specific type III polyketide synthase that catalyzes the first committed step in (iso)flavonoid biosynthesis in plants.ResultsHere we performed a genome-wide search of CHS genes in soybean, and identified 21 GmCHS loci containing 14 unique GmCHS (GmCHS1-GmCHS14) that included 5 newly identified GmCHSs (GmCHS10-GmCHS14). Furthermore, 3 copies of GmCHS3 and 2 copies of GmCHS4 were found in soybean. Analysis of gene structure of GmCHSs revealed the presence of a single intron in protein-coding regions except for GmCHS12 that contained 3 introns. Even though GmCHS genes are located on 8 different chromosomes, a large number of these genes are present on chromosome 8 where they form 3 distinct clusters. Expression analysis of GmCHS genes revealed tissue-specific expression pattern, and that some GmCHS isoforms localize in the cytoplasm and the nucleus while other isoforms are restricted to cytoplasm only.ConclusionOverall, we have identified 21 GmCHS loci with 14 unique GmCHS genes in the soybean genome. Their gene structures and genomic organization together with the spatio-temporal expression and protein localization suggest their importance in the production of downstream metabolites such as (iso)flavonoids and their derived phytoalexins.

Genome-wide analysis of Cyclophilin gene family in soybean (Glycine max).

Project description:Cyclophilins (CYPs) belong to the immunophilin superfamily, and have peptidyl-prolyl cis-trans isomerase (PPIase) activity. PPIase catalyzes cis- and trans-rotamer interconversion of the peptidyl-prolyl amide bond of peptides, a rate-limiting step in protein folding. Studies have demonstrated the importance of many PPIases in plant biology, but no genome-wide analysis of the CYP gene family has been conducted for a legume species.Here we performed a comprehensive database survey and identified a total of 62 CYP genes, located on 18 different chromosomes in the soybean genome (GmCYP1 to GmCYP62), of which 10 are multi- and 52 are single-domain proteins. Most of the predicted GmCYPs clustered together in pairs, reflecting the ancient genome duplication event. Analysis of gene structure revealed the presence of introns in protein-coding regions as well as in 5' and 3' untranslated regions, and that their size, abundance and distribution varied within the gene family. Expression analysis of GmCYP genes in soybean tissues displayed their differential tissue specific expression patterns.Overall, we have identified 62 CYP genes in the soybean genome, the largest CYP gene family known to date. This is the first genome-wide study of the CYP gene family of a legume species. The expansion of GmCYP genes in soybean, and their distribution pattern on the chromosomes strongly suggest genome-wide segmental and tandem duplications.

Genome-wide sequence characterization and expression analysis of major intrinsic proteins in soybean (Glycine max L.).

Project description:Water is essential for all living organisms. Aquaporin proteins are the major facilitator of water transport activity through cell membranes of plants including soybean. These proteins are diverse in plants and belong to a large major intrinsic (MIP) protein family. In higher plants, MIPs are classified into five subfamilies including plasma membrane intrinsic proteins (PIP), tonoplast intrinsic proteins (TIP), NOD26-like intrinsic proteins (NIP), small basic intrinsic proteins (SIP), and the recently discovered X intrinsic proteins (XIP). This paper reports genome wide assembly of soybean MIPs, their functional prediction and expression analysis. Using a bioinformatic homology search, 66 GmMIPs were identified in the soybean genome. Phylogenetic analysis of amino acid sequences of GmMIPs divided the large and highly similar multi-gene family into 5 subfamilies: GmPIPs, GmTIPs, GmNIPs, GmSIPs and GmXIPs. GmPIPs consisted of 22 genes and GmTIPs 23, which showed high sequence similarity within subfamilies. GmNIPs contained 13 and GmSIPs 6 members which were diverse. In addition, we also identified a two member GmXIP, a distinct 5(th) subfamily. GmMIPs were further classified into twelve subgroups based on substrate selectivity filter analysis. Expression analyses were performed for a selected set of GmMIPs using semi-quantitative reverse transcription (semi-RT-qPCR) and qPCR. Our results suggested that many GmMIPs have high sequence similarity but diverse roles as evidenced by analysis of sequences and their expression. It can be speculated that GmMIPs contains true aquaporins, glyceroporins, aquaglyceroporins and mixed transport facilitators.

Genome-wide identification and expression analysis of the 14-3-3 gene family in soybean (Glycine max).

Project description:In eukaryotes, proteins encoded by the 14-3-3 genes are ubiquitously involved in the plant growth and development. The 14-3-3 gene family has been identified in several plants. In the present study, we identified 22 GmGF14 genes in the soybean genomic data. On the basis of the evolutionary analysis, they were clustered into ? and non-? groups. The GmGF14s of two groups were highly conserved in motifs and gene structures. RNA-seq analysis suggested that GmGF14 genes were the major regulator of soybean morphogenesis. Moreover, the expression level of most GmGF14s changed obviously in multiple stress responses (drought, salt and cold), suggesting that they have the abilities of responding to multiple stresses. Taken together, this study shows that soybean 14-3-3s participate in plant growth and can response to various environmental stresses. These results provide important information for further understanding of the functions of 14-3-3 genes in soybean.
