Abstract Background: Amino acid transporters (AATs), which transport amino acids across cellular membranes, play important roles in alleviating plant damage under stresses as well as in plant growth and development. Although this family has been systematically studied in many plant species, little is known about the AAT genes in bread wheat ( Triticum aestivum L.) due to its complex genome sequence. Results: In this study, a total of 296 AAT genes were identified from the latest wheat genome sequence (IWGSC v1.1) and classified into twelve distinct subfamilies based upon their sequence composition and phylogenetic relationship. Wheat AAT family members showed significant heterogeneity in chromosome distribution, with relatively high density in specific chromosomal regions. Comparison the number variation of gene copies and transmembrane regions of AAT genes in different sub-genome showed that the functional adaptation of the wheat AAT family during wheat polyploidization was driven mainly by sequence mutations rather than copy number variation. In addition, it was confirmed that changes in gene structure and protein conserved domains played important roles in the functional differentiation of the AAT family. Finally, the expression profiles of these TaAAT genes under heat, drought and salt stress and in the development stage of wheat showed that the expression of TaAATs exhibited abundant and distinct expression patterns under different abiotic stresses or in different tissues, and several important candidate AAT genes that may affect abiotic stress response and grain quality were also identified. Conclusions : In this study, a total of 297 AAT proteins were systematically identified and characterized. Our study highlighted the important roles of gene duplication events in the expansion and functional differentiation of the wheat AAT family. The expression profiles of TaAATs revealed their importance for the grain development of wheat and their response to biotic and abiotic stresses. Our study also provided a theoretical basis for the further functional identification and utilization of the AAT gene family in wheat or other crops.

The TIFY gene family is specific to land plants, exerting immense influence on plant growth and development as well as responses to biotic and abiotic stresses. Here, we identify 25 TIFY genes in the poplar (Populus trichocarpa) genome. Phylogenetic tree analysis revealed these PtrTIFY genes were divided into four subfamilies within two groups. Promoter cis-element analysis indicated most PtrTIFY genes possess stress- and phytohormone-related cis-elements. Quantitative real-time reverse transcription polymerase chain reaction (qRT–PCR) analysis showed that PtrTIFY genes displayed different expression patterns in roots under abscisic acid, methyl jasmonate, and salicylic acid treatments, and drought, heat, and cold stresses. The protein interaction network indicated that members of the PtrTIFY family may interact with COI1, MYC2/3, and NINJA. Our results provide important information and new insights into the evolution and functions of TIFY genes in P. trichocarpa.

Cell walls play an important role in the structure and morphology of plants as well as stress response, including various biotic and abiotic stresses. Although the comprehensive analysis of genes involved in cellulose synthase have been performed in model plants, such as Arabidopsis thaliana and rice, information regarding cellulose synthase-like (Csl) genes in maize is extremely limited. In this study, a total of 56 members of Csl gene family were identified in maize genome, which were classified into six subfamilies. Analysis of gene structure and conserved motif indicated functional similarities among the ZmCsl proteins within the same subfamily. Additionally, the 56 ZmCsl genes were dispersed on 10 chromosomes. The expression patterns of ZmCsl genes in different tissues using the transcriptome data revealed that most of ZmCsl genes had a relatively high expression in root and tassel tissues. Moreover, the expression profiles of ZmCsl genes under drought and re-watering indicated that the expression of ZmCsl genes were mainly responsive to early stage of drought stress. The protein-protein interaction network of ZmCsl genes proposed some potential interacted proteins. The data presented a comprehensive survey of Csl gene family in maize. The detailed description of maize Csl genes will be beneficial to understand their structural, functional, and evolutionary features. Importantly, we have described the differential expression profiles of these members across different tissues and under drought. This information will provide an important foundation for studying the roles of these ZmCsl genes in response to biotic and abiotic stresses.

Abstract Background: Multidrug and toxic compound extrusion (MATE) proteins are involved in many physiological functions of plant growth and development. Although an increasing number of MATE proteins have been identified, the understanding of MATE proteins is still very limited in rice.Results: In this study, 46 MATE proteins were identified from the rice (Oryza sativa) genome by homology searches and domain prediction. In addition, physical and chemical properties of the encoded proteins, subcellular localization, chromosome localization, stress-related cis-elements in abiotic stresses were determined, and a phylogenetic analysis and conserved motif analysis were performed. The rice MATE family can be divided into four subfamilies. It is speculated that members of the rice MATE family have many potential functions, such as the transport and accumulation of flavonoids and alkaloids, the extrusion of plant or exogenous compounds, the regulation of disease resistance and the response to abiotic stress, based on the proteins and cis-acting elements with known functions in the same subfamily. Analysis of gene expression showed that most of the genes were constitutively expressed. Furthermore, eight MATE genes were chosen for qRT-PCR-based analysis and showed differential expression patterns in response to salt and drought stress. Conclusions: Phylogenetic analysis, element prediction, expression data and homology with other species provided strong evidence for functional homology of MATE gene in rice. The analysis results of this study provide comprehensive information on the MATE gene family in rice and will aid in understanding the functional divergence of MATE genes.

We analyzed the nucleotide variability and the expression profile of DREB genes from common bean, a crop of high economic and nutritional value throughout the world but constantly affected by abiotic stresses in cultivation areas. As DREB genes have been constantly associated with abiotic stress tolerance, we systematically categorized 54 putative PvDREB genes distributed in the common bean genome. It involved from AP2 domain location and amino acid conservation analysis (valine at the 14th position) to the identification of conserved motifs within peptide sequences representing six subgroups (A-1 to A-6) of PvDREB proteins. Four genes (PvDREB1F, PvDREB2A, PvDREB5A, and PvDREB6B) were cloned and analyzed for their expression profiles under abiotic stresses and their nucleotide and amino acid diversity in genotypes of Andean and Mesoamerican origin, showing distinct patterns of expression and nucleotide variability. PvDREB1F and PvDREB5A showed high relative inducibilities when genotypes of common bean were submitted to stresses by drought, salt, cold, and ABA. PvDREB2A inducibility was predominantly localized to the stem under drought. PvDREB6B was previously described as an A-2 (DREB2) gene, but a detailed phylogenetic analysis and its expression profile clearly indicated it belongs to group A-6. PvDREB6B was found as a cold- and dehydration-responsive gene, mainly in leaves. Interestingly, PvDREB6B also showed a high nucleotide and amino acid diversity within its coding region, in comparison to the others, implicating in several nonsynonymous amino acid substitutions between Andean and Mesoamerican genotypes. The expression patterns and nucleotide diversity of each DREB found in this study revealed fundamental characteristics for further research aimed at understanding the molecular mechanisms associated with drought, salt, and cold tolerance in common bean, which could be performed based on association mapping and functional analyses.

The β-amylase (BAM) gene family, known for their property of catalytic ability to hydrolyze starch to maltose units, has been recognized to play critical roles in metabolism and gene regulation. To date, BAM genes have not been characterized in oil crops. In this study, the genome-wide survey revealed the identification of 30 BnaBAM genes in Brassica napus L. (B. napus L.), 11 BraBAM genes in Brassica rapa L. (B. rapa L.), and 20 BoBAM genes in Brassica oleracea L. (B. oleracea L.), which were divided into four subfamilies according to the sequence similarity and phylogenetic relationships. All the BAM genes identified in the allotetraploid genome of B. napus, as well as two parental-related species (B. rapa and B. oleracea), were analyzed for the gene structures, chromosomal distribution and collinearity. The sequence alignment of the core glucosyl-hydrolase domains was further applied, demonstrating six candidate β-amylase (BnaBAM1, BnaBAM3.1-3.4 and BnaBAM5) and 25 β-amylase-like proteins. The current results also showed that 30 BnaBAMs, 11 BraBAMs and 17 BoBAMs exhibited uneven distribution on chromosomes of Brassica L. crops. The similar structural compositions of BAM genes in the same subfamily suggested that they were relatively conserved. Abiotic stresses pose one of the significant constraints to plant growth and productivity worldwide. Thus, the responsiveness of BnaBAM genes under abiotic stresses was analyzed in B. napus. The expression patterns revealed a stress-responsive behaviour of all members, of which BnaBAM3s were more prominent. These differential expression patterns suggested an intricate regulation of BnaBAMs elicited by environmental stimuli. Altogether, the present study provides first insights into the BAM gene family of Brassica crops, which lays the foundation for investigating the roles of stress-responsive BnaBAM candidates in B. napus.

Abstract Background Amino acid transporters (AATs) plays an essential roles in growth and development of plants, including amino acids long-range transport, seed germination, quality formation, responsiveness to pathogenic bacteria and abiotic stress by modulating the transmembrane transfer of amino acids. In this study, we performed a genome-wide screening to analyze the AAT genes in foxtail millet (Setaria italica L.), especially those associated with quality formation and abiotic stresses response. Results A total number of 94 AAT genes were identified and divided into 12 subfamilies by their sequence characteristics and phylogenetic relationship. A large number (58/94, 62%) of AAT genes in foxtail millet were expanded via gene duplication, involving 13 tandem and 12 segmental duplication events. Tandemly duplicated genes had a significant impact on their functional differentiation via sequence variation, structural variation and expression variation. Further comparison in multiple species showed that in addition to paralogous genes, the expression variations of the orthologous AAT genes also contributed to their functional differentiation. The transcriptomic comparison of two millet cultivars verified the direct contribution of the AAT genes such as SiAAP1, SiAAP8, and SiAUX2 in the formation of grain quality. In addition, the qRT-PCR analysis suggested that several AAT genes continuously responded to diverse abiotic stresses, such as SiATLb1, SiANT1. Finally, combined with the previous studies and analysis on sequence characteristics and expression patterns of AAT genes, the possible functions of the foxtail millet AAT genes were predicted. Conclusion This study for the first time reported the evolutionary features, functional differentiation, roles in the quality formation and response to abiotic stresses of foxtail millet AAT gene family, thus providing a framework for further functional analysis of SiAAT genes, and also contributing to the applications of AAT genes in improving the quality and resistance to abiotic stresses of foxtail millet, and other cereal crops.

Acetylserotonin methyltransferase (ASMT) in plant species, one of the most important enzymes in melatonin biosynthesis, plays a rate-limiting role in the melatonin production. In this study, based on the whole genome sequence, we performed a systematic analysis for the ASMT gene family in pepper (Capsicum annuum L.) and analyzed their expression profiles during growth and development, as well as abiotic stresses. The results showed that at least 16 CaASMT genes were identified in the pepper genome. Phylogenetic analyses of all the CaASMTs were divided into three groups (group I, group II, and group III) with a high bootstrap value. Through the online MEME tool, six distinct motifs (motif 1 to motif 6) were identified. Chromosome location found that most CaASMT genes were mapped in the distal ends of the pepper chromosomes. In addition, RNA-seq analysis revealed that, during the vegetative and reproductive development, the difference in abundance and distinct expression patterns of these CaASMT genes suggests different functions. The qRT-PCR analysis showed that high abundance of CaASMT03, CaASMT04, and CaASMT06 occurred in mature green fruit and mature red fruit. Finally, using RNA-seq and qRT-PCR technology, we also found that several CaASMT genes were induced under abiotic stress conditions. The results will not only contribute to elucidate the evolutionary relationship of ASMT genes but also ascertain the biological function in pepper plant response to abiotic stresses.
