Abstract Background Mitogen-activated protein kinase (MAPK) cascade is a conserved and universal signal transduction module in organism. Although it has been well characterized in many plants, no systematic analysis has been conducted in the model cereal crop barley. Results Here, we identified 20 MAPKs, 6 MAPKKs and 156 MAPKKKs through a genome-wide search method using the latest published barley genomic data. Phylogenetic analysis assigned all the MAPK cascade genes into three groups in accordance to MAPK, MAPKK and MAPKKK family. Gene duplication revealed that segmental and tandem duplication events contributed to the expansion of barley MAPK cascade genes and the duplicated gene pairs were found to undergone strong purifying selection. Expression profiles of the HvMAPK, HvMAPKK and HvMAPKKKs were then investigated in different organs and under diverse stresses using the available 132 RNA-seq datasets, and then the tissue-specific and stress-responsive ones were found. Finally, co-expression regulatory network of MAPK cascade genes was constructed by WGCNA tool, resulting in a complicated network composed of a total of 72 branches containing 46 HvMAPK cascade genes and 46 miRNAs. Conclusion This study provides the candidates for further functional studies and also contribute to better understand the MAPK cascade regulatory network in barley and beyond.

Abstract Background Mitogen Activated Protein Kinase (MAPK) cascade is a fundamental pathway in organisms for signal transduction. Though it is well characterized in various plants, there is no systematic study of this cascade in tea. Result In this study, 5 genes of Mitogen Activated Protein Kinase Kinase (MKK) and 16 genes of Mitogen Activated Protein Kinase (MPK) in Camellia sinensis were found through a genome-wide search taking Arabidopsis thaliana as the reference genome. Also, phylogenetic relationships along with structural analysis which includes gene structure, location as well as protein conserved motifs and domains, were systematically examined and further, predictions were validated by the results. The plant species taken for comparative study clearly displayed segmental duplication, which was a significant candidate for MAPK cascade expansion. Also, functional interaction was carried out in C. sinensis based on the orthologous genes in Arabidopsis. The expression profiles linked to various stress treatments revealed wide involvement of MAPK and MAPKK genes from Tea in response to various abiotic factors. In addition, the expression of these genes was analysed in various tissues. Conclusion This study provides the targets for further comprehensive identification, functional study, and also contributed for a better understanding of the MAPK cascade regulatory network in C. sinensis.

Abstract Background: In citrus, genetic improvement via biotechnology is hindered by the obstacle of in vitro regeneration via somatic embryogenesis (SE). Although a few B3 transcription factors are reported to regulate embryogenesis, little is known about the B3 superfamily in citrus, and which members might be involved in SE.Results: Genome-wide sequence analysis identified 72 (CsB3) and 69 (CgB3) putative B3 superfamily members in the genomes of sweet orange (Citrus sinensis, polyembryonic) and pummelo (C. grandis, monoembryonic), respectively. Genome duplication analysis indicated that segmental and tandem duplication events contributed to the expansion of the B3 superfamily in citrus, and that the B3 superfamily evolved under the effect of purifying selection. Phylogenetic relationships were well supported by conserved gene structure and motifs outside the B3 domain, which allowed possible functions to be inferred by comparison with homologous genes from Arabidopsis. Expression analysis identified 23 B3 superfamily members that were expressed during SE in citrus and 17 that may play functional roles at late SE stages. Eight B3 genes were identified that were specific to the genome of polyembryonic sweet orange compared to monoembryonic pummelo. Of these eight B3 genes, CsARF19 was found to be specifically expressed at higher levels in embryogenic callus (EC), implying its possible involvement in EC initiation. Conclusions: This study provides a genome-wide analysis of the citrus B3 superfamily, including its genome organization, evolutionary features and expression profiles, and identifies specific family members that may be associated with SE.

The multidrug and toxic compound extrusion (MATE) protein family is important in the export of toxins and other substrates, but detailed information on this family in the Brassicaceae has not yet been reported compared to Arabidopsis thaliana. In this study, we identified 57, 124, 81, 85, 130, and 79 MATE genes in A. thaliana, Brassica napus, Brassica oleracea, Brassica rapa, Brassica juncea, and Brassica nigra, respectively, which were unevenly distributed on chromosomes owing to both tandem and segmental duplication events. Phylogenetic analysis showed that these genes could be classified into four subgroups, shared high similarity and conservation within each group, and have evolved mainly through purifying selection. Furthermore, numerous B. napusMATE genes showed differential expression between tissues and developmental stages and between plants treated with heavy metals or hormones and untreated control plants. This differential expression was especially pronounced for the Group 2 and 3 BnaMATE genes, indicating that they may play important roles in stress tolerance and hormone induction. Our results provide a valuable foundation for the functional dissection of the different BnaMATE homologs in B. napus and its parental lines, as well as for the breeding of more stress-tolerant B. napus genotypes.

Salt stress affects the plant growth and productivity worldwide and NHX is one of those genes that are well known to improve salt tolerance in transgenic plants. It is well characterized in several plants, such as Arabidopsis thaliana and cotton; however, not much is known about NHXs in tea plant. In the present study, NHX genes of tea were obtained through a genome-wide search using A. thaliana as reference genome. Out of the 9 NHX genes in tea, 7 genes were localized in vacuole while the remaining 2 genes were localized in the endoplasmic reticulum (ER; CsNHX8) and plasma membrane (PM; CsNHX9), respectively. Furthermore, phylogenetic relationships along with structural analysis which includes gene structure, location, and protein-conserved motifs and domains were systematically examined and further, predictions were validated by the expression analysis. The dN/dS values show that the majority of tea NHX genes is subjected to strong purifying selection under the course of evolution. Also, functional interaction was carried out in Camellia sinensis based on the orthologous genes in A. thaliana. The expression profiles linked to various stress treatments revealed wide involvement of NHX genes from tea in response to various abiotic factors. This study provides the targets for further comprehensive identification, functional study, and also contributed for a better understanding of the NHX regulatory network in C. sinensis.

Gibberellins (GAs), a class of phytohormones, act as an essential natural regulator of plant growth and development. Many studies have shown that GA is related to rhizobial infection and nodule organogenesis in legume species. However, thus far, GA metabolism and signaling components are largely unknown in the model legume Medicago truncatula. In this study, a genome-wide analysis of GA metabolism and signaling genes was carried out. In total 29 components, including 8 MtGA20ox genes, 2 MtGA3ox genes, 13 MtGA2ox genes, 3 MtGID1 genes, and 3 MtDELLA genes were identified in M. truncatula genome. Expression profiles revealed that most members of MtGAox, MtGID1, and MtDELLA showed tissue-specific expression patterns. In addition, the GA biosynthesis and deactivation genes displayed a feedback regulation on GA treatment, respectively. Yeast two-hybrid assays showed that all the three MtGID1s interacted with MtDELLA1 and MtDELLA2, suggesting that the MtGID1s are functional GA receptors. More importantly, M. truncatula exhibited increased plant height and biomass by ectopic expression of the MtGA20ox1, suggesting that enhanced GA response has the potential for forage improvement.

Abstract Background:AP2/ERF transcription factors perform indispensable functions in various biological processes, such as plant growth, development, biotic and abiotic stresses responses. The AP2/ERF transcription factor family has been identified in many plants, and several AP2/ERF transcription factors from Arabidopsis (Arabidopsis thaliana) have been functionally characterized. However, little research has been conducted on the AP2/ERF genes of ginger (Zingiber officinale), which is an important edible and medicinal horticultural plant. The recently published whole genome sequence of ginger allowed us to study the tissue and expression profiles of AP2/ERF genes in ginger on a genome-wide basis.Results:In this study, 163 AP2/ERF genes of ginger (ZoAP2/ERF) were identified and renamed according to the chromosomal distribution of the ZoAP2/ERF genes. According to the number conserved domains and gene structure, the AP2/ERF genes were divided into three subfamilies by phylogenetic analysis, namely, AP2 (35 members), ERF (125 members) and RAV (3 members). A total of 10 motifs were detected in ginger AP2/ERF genes, and some of the unique motifs were found to be important for the function of ZoAP2/ERF genes.Conclusion:A comprehensive analysis of AP2/ERF gene expression patterns in different tissues and rhizome development stages by transcriptom sequence and quantitative real-time PCR (qRT-PCR) showed that they played an important role in the growth and development of ginger, and genes that might regulate rhizome and flower development were preliminarily identified. This systematic analysis establishes a foundation for further studies of the functional characteristics of ZoAP2/ERF genes and improvement of ginger.

AbstractJAZ is a plant-specific protein family involved in the regulation of plant development, abiotic stresses, and responses to phytohormone treatments. In this study, we carried out a bioinformatics analysis of JAZ genes in turnip by determining the phylogenetic relationship, chromosomal location, gene structure and expression profiles analysis under stresses. The 36 JAZ genes were identified and classified into four subfamilies (ZML, JAZ, PPD and TIFY). The JAZ genes were located on 10 chromosomes. Two gene pairs were involved in tandem duplication events. We identified 44 collinear JAZ gene pairs in the turnip genome. Analysis of the Ka/Ks ratios indicated that the paralogs of the BrrJAZ family principally underwent purifying selection. Expression analysis suggested JAZ genes may be involved in the formation of turnip tuberous root, and they also participated in the response to ABA, SA, MeJA, salt stress and low-temperature stress. The results of this study provided valuable information for further exploration of the JAZ gene family in turnip.
