AbstractThe hexokinase (HXK) gene family, whose members play vital roles in sugar induction signals and glycolysis in organisms, is widely found in plants. Although some hexokinase genes have been studied in maize, a systematic report of the gene family and its role in plant resistance is lacking. In this study, 10 hexokinase genes were systematically identified in maize based on the maize genome-wide database. Phylogenetic analysis divides the maize HXK protein family into four clusters. Prediction of cis-regulatory elements showed that a number of elements responding to abiotic stress exist in the promoter of hexokinase genes. The expression profile of these genes, originated from B73, showed that different members of hexokinase genes are highly expressed in roots and leaves of maize under salt or drought stress, which is similar to that of Mo17.The coding sequence of ZmHXK7 gene, isolated from maize B73, was constructed into plant expression vector pMDC45 and then transformed into athxk3 (Salk_022188C). By hyg resistance detection, PCR analysis, and western blot confirmation, the homozygous progenies of transgenic Arabidopsis lines were identified. Subcellular localization analysis showed that the ZmHXK7 gene was located in cytosol. Seedling growth and salt stress inhibition in complementary mutant plants of ZmHXK7 gene were significantly improved, and enhanced salt tolerance was displayed. Our study provides insights into the evolution and expression patterns of the hexokinase gene and show that maize ZmHXK7 proteins play an important role in resisting salt stress, which will be useful in plant breeding for abiotic stress resistance.

Abstract BackgroundPlant specific YABBY transcription factors have important biological roles in plant growth and abiotic stress. However, the identification of Cucurbita Linn. YABBY and their response to salt stress have not yet been reported. The gene number, gene distribution on chromosome, gene structure, protein conserved structure, protein motif and the cis-acting element of YABBY in three cultivars of Cucurbita Linn. were analyzed by bioinformatics tools, and their tissue expression patterns and expression profile under salt stress were analyzed.ResultsIn this study, 34 YABBY genes (11 CmoYABBYs in Cucurbita moschata, 12 CmaYABBYs in Cucurbita maxima, and 11 CpeYABBYs in Cucurbita pepo) were identified and they were divided into five subfamilies (YAB1/YAB3, YAB2, INO, CRC and YAB5). YABBYs in the same subfamily usually have similar gene structures (intron-exon distribution) and conserved domains. Chromosomal localization analysis showed that these CmoYABBYs, CmaYABBYs, and CpeYABBYs were unevenly distributed in 8, 9, and 9 chromosomes of 21 chromosomes, respectively. Total of 6 duplicated gene pairs, and they all experienced segmental duplication events. Cis-acting element analysis showed that some Cucurbita Linn. YABBYs were associated with at least one of plant hormone response, plant growth, and abiotic stress response. Transcriptional profiles of CmoYABBYs and CmaYABBYs in roots, stems, leaves, and fruits, and CpeYABBYs in seed and fruit mesocarp showed that YABBYs of Cucurbita Linn. had tissue specificity. Finally, the transcriptional profile of 11 CmoYABBYs in leaf and qRT-PCR analysis of CmoYABBYs in root under salt stress indicated that some genes may play an important role in salt stress.ConclusionsGenome-wide identification and expression analysis of YABBYs revealed the characteristics of YABBY gene family in three cultivars of Cucurbita Linn.. Transcriptome and qRT-PCR analysis revealed the response of the CmoYABBYs to salt stress.This provides a theoretical basis for the functional research and utilization of YABBY genes in Cucurbita Linn..

Abstract Background Nuclear factor Y (NF-Y) gene family consists of NF-YA, NF-YB and NF-YC subfamilies. Many members of NF-Y family have been involved in plant development processes, phytohormone signaling and tolerance to stresses in Arabidopsis and other plant species. However, little attention has been given in peanut. Results A total of 33 AhNF-Y genes (AhNF-Ys) were identified and distributed on 16 chromosomes. A phylogenetic analysis indicated that NF-Y genes prossessed highly conservatism in different plants. Gene duplication analyze indicated that only segmental duplication were detected. The abiotic stress-related regulatory elements analysis showed that AhNF-Ys, except for AhNF-YB6, contained at least one abiotic stress response element. With RNA-seq data, the tissue/organ-specific expression and differential expression profiling under salt stress were analyzed, indicating that six selected AhNF-Y gene may play potential roles in the regulation of salt stress response. qRT-PCR results suggested that these AhNF-Y genes also responded to osmotic, ABA (Abscisic Acid) and SA (Salicylic acid) stresses. Conclusions In this study, thirty three AhNF-Y genes were identified in cultivated peanut and the phylogeny, gene structures, motif composition, chromosomal location, gene duplication, stress-related regulatory elements, and expression patterns were also examined. These results may contribute to functional characterization of AhNF-Y genes in further research.

Abstract Background The calcium (Ca2+)-dependent phospholipid binding protein annexin gene family, which is known to be related to membrane lipid and cytoskeletal components, is involved in a diverse range of biological functions. However, in cassava (Manihot esculenta Crantz), no studies focusing on the roles of annexin genes in response to abiotic stresses, calcium, and hormones have been informed. Results 12 annexin genes were found and assigned to eight chromosomes in the cassava genome. All of the MeAnns contain a typical annexin domain with four 70-amino acid repeats. The MeAnns are classified into six groups in the phylogenetic tree. In their promoter regions, MeAnns possess at least 3 hormone response-related cis-elements and 1 abiotic stress response-related cis-acting element. MeAnn1, MeAnn2 and MeAnn5 exhibit very high levels of expression in each tested organs or tissues. By contrast, MeAnn12 exhibits very low levels in all the tested organs or tissues. qRT-PCR analysis indicates that both MeAnn5 and MeAnn9 have significantly high expression in leaves after cold, drought, and salt treatments and are highly responsive to CaCl2, GA and JA treatments. MeAnn2 and MeAnn10 are significantly downregulated in leaves by cold, drought and salt stress and negatively respond to CaCl2, GA and JA. The expression patterns of MeAnns under cold, drought, and salt stress are irregular in shoots. In roots, MeAnn1 and MeAnn9 are downregulated by cold, CaCl2 and JA treatments, while their other gene expression patterns are irregular. Conclutions In this study, we identified annexin genes in cassava and our expression profiling analysis demonstrated that cassava annexin genes responded to multiple stresses. Our results laid the foundation for further study of the function of cassava anesxin genes and provided an entry point for understanding the response mechanism of cassava to abiotic stress.

Wox Genes

WUSCHEL-related homeobox (WOX) is a family of transcription factors that are unique to plants and is characterized by the presence of a homeodomain. The WOX transcription factor plays an important role in regulating plant growth and development and the response to abiotic stress. Soybean is one of the most important oil crops worldwide. In this study, based on the available genome data of soybean, the WOX gene family was identified by bioinformatics analysis. The chromosome distribution, gene and protein structures, phylogenetic relationship and gene expression patterns of this family were comprehensively compared. The results showed that a total of 33 putative WOX genes in the soybean genome were found and then designated as GmWOX1- GmWOX33, which were distributed across 19 chromosomes except chromosome 16. Multiple sequence analysis of the GmWOX gene family revealed a highly conserved homeodomain. Phylogenetic tree analysis showed that 33 WOX genes could be divided into three major clades (modern/WUS, intermediate and ancient) in soybean. Of these 33 WOX genes, some showed differential expression patterns in the tested tissues (leaves, pods, unopen and open flowers, nodules, seed, roots, root hairs, stems, shoot apical meristems and shoot tips). In addition, the expression profile and qRT-PCR analysis showed that most of the GmWOX genes responded to different abiotic stress treatments (cold and drought). According to the expression pattern of GmWOX genes in the high regeneration capacity soybean material P3, overexpression of GmWOX18 was selected for function analysis. The overexpression of GmWOX18 increased the regeneration ability of clustered buds. The results will provide valuable information for further studies on the roles of WOX genes in regulating soybean growth, development and responses to abiotic stress, as well as a basis for the functional identification and analysis of WOX genes in soybean.

Stress-associated proteins (SAPs) are novel A20/AN1 zinc finger domain-containing proteins that are now favorable targets to improve abiotic stress tolerance in plants. However, the SAP gene family and their biological functions have not been identified in the important fruit crop apple (Malus × domestica Borkh.). We conducted a genome-wide analysis and cloning of this gene family in apple and determined that the overexpression of MdSAP15 enhances drought tolerance in Arabidopsis plants. We identified 30 SAP genes in the apple genome. Phylogenetic analysis revealed two major groups within that family. Results from sequence alignments and analyses of 3D structures, phylogenetics, genomics structure, and conserved domains indicated that apple SAPs are highly and structurally conserved. Comprehensive qRT-PCR analysis found various expression patterns for MdSAPs in different tissues and in response to a water deficit. A transgenic analysis showed that the overexpression of MdSAP15 in transgenic Arabidopsis plants markedly enhanced their tolerance to osmotic and drought stresses. Our results demonstrate that the SAP genes are highly conserved in plant species, and that MdSAP15 can be used as a target gene in genetic engineering approaches to improve drought tolerance.

Background Golden2-Like (GLK) transcription factors are a type of transcriptional regulator in plants. They play a pivotal role in the plant physiological activity process and abiotic stress response. Methods In this study, the potential function of GLK family genes in Gossypium hirsutum was studied based on genomic identification, phylogenetic analysis, chromosome mapping and cis-regulatory elements prediction. Gene expression of nine key genes were analyzed by qRT-PCR experiments. Results Herein, we identified a total of 146 GhGLK genes in Gossypium hirsutum, which were unevenly distributed on each of the chromosomes. There were significant differences in the number and location of genes between the At sub-genome and the Dt sub-genome. According to the phylogenetic analysis, they were divided into ten subgroups, each of which had very similar number and structure of exons and introns. Some cis-regulatory elements were identified through promoter analysis, including five types of elements related to abiotic stress response, five types of elements related to phytohormone and five types of elements involved in growth and development. Based on public transcriptome data analysis, we identified nine key GhGLKs involved in salt, cold, and drought stress. The qRT-PCR results showed that these genes had different expression patterns under these stress conditions, suggesting that GhGLK genes played an important role in abiotic stress response. This study laid a theoretical foundation for the screening and functional verification of genes related to stress resistance of GLK gene family in cotton.

Abstract Background: Lectin receptor-like kinases (LecRLKs) are a class of membrane proteins found in plants that are involved in diverse functions, including plant development and stress responses. Although LecRLK families have been identified in a variety of plants, a comprehensive analysis has not yet been undertaken in cucumber (Cucumis sativus L.). Results: In this study, 46 putative LecRLK genes were identified in cucumber genome, including 23 G-type, 22 L-type and 1 C-type LecRLK genes. They unequally distributed on all 7 chromosomes with a clustering trendency. Most of the genes in the cucumber LecRLK (CsLecRLK) gene family lacked introns. In addition, there were many regulatory elements associated with phytohormone and stress on these genes’ promoters. Transcriptome data demonstrated that distinct expression patterns of CsLecRLK genes in various tissues. Furthermore, we found that each member of the CsLecRLK family had its own unique expression pattern under hormone and stress treatment by the quantitative real time PCR (qRT-PCR) analysis.Conclusion: This study provides a better understanding of the evolution and function of LecRLK gene family in cucumber, and opens the possibility to explore the roles that LecRLKs might play in the life cycle of cucumber.

Abstract Background Alba (Acetylation lowers binding affinity) proteins are an ancient family of nucleic acid-binding proteins that function in gene regulation, RNA metabolism, mRNA translatability, developmental processes, and stress adaptation. However, comprehensive bioinformatics analysis on the Alba gene family of Solanum lycopersicum has not been reported previously.Results In the present study, we undertook the first comprehensive genome-wide characterization of the Alba gene family in tomato (Solanum lycopersicum L.). We identified eight tomato Alba genes, which were classified into two groups: genes containing a single Alba domain and genes with a generic Alba domain and RGG/RG repeat motifs. Cis-regulatory elements and target sites for miRNAs, which function in plant development and stress responses, were prevalent in SlAlba genes. To explore the structure–function relationships of tomato Alba proteins, we predicted their 3D structures, highlighting their likely interactions with several putative ligands. Confocal microscopy revealed that SlAlba–GFP fusion proteins were localized to the nucleus and cytoplasm, consistent with putative roles in various signaling cascades. Expression profiling revealed the differential expression patterns of most SlAlba genes across diverse organs. SlAlba1 and SlAlba2 were predominantly expressed in flowers, whereas SlAlba5 expression peaked in 1 cm-diameter fruits. The SlAlba genes were differentially expressed (up- or downregulated) in response to different abiotic stresses. Furthermore, all but one of these genes were induced by abscisic acid treatment, pointing to their possible regulatory roles in stress tolerance via an abscisic acid-dependent pathway.Conclusions Our characterization of SlAlba genes should facilitate the discovery of additional genes associated with organ and fruit development as well as abiotic stress adaptation in tomato.

F-box genes play an important role in the growth and development of plants, but there are few studies on its role in a plant’s response to abiotic stresses. In order to further study the functions of F-box genes in tomato (Solanum lycopersicum, Sl), a total of 139 F-box genes were identified in the whole genome of tomato using bioinformatics methods, and the basic information, transcript structure, conserved motif, cis-elements, chromosomal location, gene evolution, phylogenetic relationship, expression patterns and the expression under cold stress, drought stress, jasmonic acid (JA) treatment and salicylic acid (SA) treatment were analyzed. The results showed that SlFBX genes were distributed on 12 chromosomes of tomato and were prone to TD (tandem duplication) at the ends of chromosomes. WGD (whole genome duplication), TD, PD (proximal duplication) and TRD (transposed duplication) modes seem play an important role in the expansion and evolution of tomato SlFBX genes. The most recent divergence occurred 1.3042 million years ago, between SlFBX89 and SlFBX103. The cis-elements in SlFBX genes’ promoter regions were mainly responded to phytohormone and abiotic stress. Expression analysis based on transcriptome data and qRT-PCR (Real-time quantitative PCR) analysis of SlFBX genes showed that most SlFBX genes were differentially expressed under abiotic stress. SlFBX24 was significantly up-regulated at 12 h under cold stress. This study reported the SlFBX gene family of tomato for the first time, providing a theoretical basis for the detailed study of SlFBX genes in the future, especially the function of SlFBX genes under abiotic stress.
