Abstract Background Alcohol dehydrogenase (ADH) plays important roles in plant survival under anaerobic conditions. Although some research has been carried out the functions of ADH in other plants, that of wheat TaADH family genes in response to abiotic stress are unclear. Results A total of 22 ADH genes were obtained from 14 chromosomes of the wheat genome by systematic screening. Multiple sequence alignment and evolutionary relationship show that these genes contain the characteristics of GroES-like domain and Zinc-binding domain, and these belong to Medium-chain -ADH type and can be divided into three subfamilies. There are 17 pairs of fragment replication genes among TaADH family members in the wheat genome, while there are 9 pairs of collinear gene pairs from ADH family members between wheat and rice genome. We speculate that these fragment repetition events may be the main reason for the amplification of TaADH family genes. Ka/Ks analysis indicated that there were 64 repetitive gene pairs, and the Ka/Ks value of these gene pairs was less than 1, which indicated that these sequences of TaADH gene were relatively conservative and did not change greatly in the process of evolution. Promoter element analysis showed that almost all of the upstream promoters of these genes contained the responsive anaerobic inducible element. Tissue localized expression and expression patterns also demonstrated that the TaADH genes responded to abiotic stress and may play an important role in waterlogging stress during the seed germination stage. Conclusions The results of this study may be helpful to further study the function of TaADH genes and determine the candidate gene for wheat stress resistance breeding.

Core Components

Abscisic acid (ABA) plays a crucial role in various aspects of plant growth and development, including fruit development and ripening, seed dormancy, and involvement in response to various environmental stresses. In almost all higher plants, ABA signal transduction requires three core components; namely, PYR/PYL/RCAR ABA receptors (PYLs), type 2C protein phosphatases (PP2Cs), and class III SNF-1-related protein kinase 2 (SnRK2s). The exploration of these three core components is not comprehensive in soybean. This study identified the GmPYL-PP2C-SnRK2s gene family members by using the JGI Phytozome and NCBI database. The gene family composition, conservation, gene structure, evolutionary relationship, cis-acting elements of promoter regions, and its coding protein domains were analyzed. In the entire genome of the soybean, there are 21 PYLs, 36 PP2Cs, and 21 SnRK2s genes; further, by phylogenetic and conservation analysis, 21 PYLs genes are classified into 3 groups, 36 PP2Cs genes are classified into seven groups, and 21 SnRK2s genes are classified into 3 groups. The conserved motifs and domain analysis showed that all the GmPYLs gene family members contain START-like domains, the GmPP2Cs gene family contains PP2Cc domains, and the GmSnRK2s gene family contains S_TK domains, respectively. Furthermore, based on the high-throughput transcriptome sequencing data, the results showed differences in the expression patterns of GmPYL-PP2C-SnRK2s gene families in different tissue parts of the same variety, and the same tissue part of different varieties. Our study provides a basis for further elucidation of the identification of GmPYL-PP2C-SnRK2s gene family members and analysis of their evolution and expression patterns, which helps to understand the molecular mechanism of soybean response to abiotic stress. In addition, this provides a conceptual basis for future studies of the soybean ABA core signal pathway.

Abstract Background: Trehalose is a nonreducing disaccharide with high stability and strong water absorption properties that can improve the resistance of organisms to various abiotic stresses. Trehalose-6-phosphate synthase (TPS) plays important roles in trehalose metabolism and signaling. Results: A full-length cDNA of ThTPS was cloned from Tamarix hispida. The phylogenetic tree among ThTPS and 11 AtTPS in Arabidopsis indicates that the ThTPS protein had a close evolutionary relationship with AtTPS7. However, the function of AtTPS7 has not been determined. To analyze the abiotic stress tolerance function of ThTPS, the expression patterns of ThTPS were monitored under salt and drought stress and JA, ABA and GA3 hormone stimulation in T. hispida by qRT-PCR. The results showed that ThTPS expression was clearly induced by these 5 kinds of treatments at at least one studied point. Particularly under salt stress, ThTPS was highly induced in the roots of T. hispda. Furthermore, the ThTPS gene was transiently overexpressed in T. hispida. The results of physiological indexes and staining showed that overexpression of the ThTPS gene increased T. hispida salt and drought stress tolerance. Conclusion: The ThTPS gene can respond to abiotic stress such as salt and drought, and overexpression of ThTPS gene can significantly improve salt and drought tolerance. These findings establish a foundation to better understand the response of TPS genes to abiotic stress in plants.

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..

SQUAMOSA promoter binding protein-like (SPL) genes are a type of plant-specific transcription factors that play crucial roles in the regulation of phase transition, floral transformation, fruit development, and various stresses. Although SPLs have been characterized in several model species, no systematic analysis has been studied in pecans, an important woody oil tree species. In this study, a total of 32 SPL genes (CiSPLs) were identified in the pecan genome. After conducting phylogenetic analysis of the conserved SBP proteins from Arabidopsis, rice, and poplar, the CiSPLs were separated into eight subgroups. The CiSPL genes within the same subgroup contained very similar exon-intron structures and conserved motifs. Nine segmentally duplicated gene pairs in the pecan genome and 16 collinear gene pairs between the CiSPL and AtSPL genes were identified. Cis-element analysis showed that CiSPL genes may regulate plant meristem differentiation and seed development, participate in various biological processes, and respond to plant hormones and environmental stresses. Therefore, we focused our study on the expression profiles of CiSPL genes during flower and fruit development. Most of the CiSPL genes were predominantly expressed in buds and/or female flowers. Additionally, quantitative real time PCR (qRT-PCR) analyses confirmed that CiSPL genes showed distinct spatiotemporal expression patterns in response to drought and salt treatments. The study provides foundation for the further exploration of the function and evolution of SPL genes in pecan.

The nuclear factor Y (NF-Y) as a transcription factor plays an important role in plants growth and development, and response to stress. However, few genome-wide analyzes and functional research of the NF-Y family has been undertaken in apple (Malus domestica Borkh.) so far. In this study, we comprehensively identified the 43 MdNF-Y genes in apple, which dispersedly distributed among the three subgroups based on their sequence alignment analysis, including 11 MdNF-YAs, 22 MdNF-YBs and 10 MdNF-YCs. The members in the same subgroups had similar evolution relationships, gene structures, and conserved motifs. The gene duplication analysis suggested that all the genes were dispersed followed by 27 segmental duplication. Moreover, based on synteny analysis of MdNF-Ys with eight plant species results suggested that some ortholog genes were preserved during the evolution of these species. Cis-element analysis showed potential functions of MdNF-Ys in apple growth and development and responded to abiotic stress. Furthermore, the interaction among MdNF-Ys protein were investigated in yeast two-hybrid assays. The expression patterns of MdNF-Ys in tissue-specific response reveled divergence and might play important role in apple growth and development. Subsequently, whole MdNF-Y genes family was carried out for RT-PCR in response to five abiotic stress (ABA, drought, heat, cold, and salinity) to identify their expression patterns. Taken together, our study will provide a foundation for the further study to the molecular mechanism of apple in growing development and response to abiotic stresses.

Abstract Background: The cryptochromes (CRY) comprise a specific blue light receptor for plants and animals, which play crucial roles in physiological processes of plant growth, development, and stress tolerance. Results: In the present work, a systematical analysis of CRY gene family from five allotetraploid cotton species, G. hirsutum, G. barbadense, G. tomentosum, G. mustelinum and G. darwinii together with seven diploid species. There were 18, 17, 17, 17, and 17 CRYs identified in G. hirsutum, G. barbadense, G. tomentosum, G. mustelinum and G. darwinii, respectively, whereas five to nine CRY genes were identified in the diploid species. Phylogenetic analysis of the protein-coding sequences revealed that CRY genes from the allotetraploids G. hirsutum and G. barbadense, three diploid cotton species (G. raimondii, G. herbaceum, and G. arboreum), and Arabidopsis thaliana could be classified into seven clades. Synteny analysis suggested that the homoeolog of G. hirsutum Gh_A02G0384 has undergone an evolutionary loss event in the other four allotetraploid cotton species. Cis-element analysis predicated the possible functions of CRY genes in G. hirsutum. Public RNA-seq data were investigated to analyze the expression patterns of G. hirsutum CRY genes in various tissues as well as gene expressions under abiotic stress treatments. Conclusion: These results indicated the possible functions of G. hirsutum CRY genes in differential tissues as well as in response to abiotic stress during the cotton plants life cycle.

Background Alcohol dehydrogenase (ADH) plays an important role in plant survival under anaerobic conditions. Although some research about ADH in many plants have been carried out, the bioinformatics analysis of the ADH gene family from Triticum aestivum and their response to abiotic stress is unclear. Methods A total of 22 ADH genes were identified from the wheat genome, and these genes could be divided into two subfamilies (subfamily I and subfamily II). All TaADH genes belonged to the Medium-chain ADH subfamily. Sequence alignment analysis showed that all TaADH proteins contained a conservative GroES-like domain and Zinc-binding domain. A total of 64 duplicated gene pairs were found, and the Ka/Ks value of these gene pairs was less than 1, which indicated that these genes were relatively conservative and did not change greatly in the process of duplication. Results The organizational analysis showed that nine TaADH genes were highly expressed in all organs, and the rest of TaADH genes had tissue specificity. Cis-acting element analysis showed that almost all of the TaADH genes contained an anaerobic response element. The expression levels of ADH gene in waterlogging tolerant and waterlogging sensitive wheat seeds were analyzed by quantitative real-time PCR (qRT-PCR). This showed that some key ADH genes were significantly responsive to waterlogging stress at the seed germination stage, and the response of waterlogging tolerant and waterlogging sensitive wheat seeds to waterlogging stress was regulated by different ADH genes. The results may be helpful to further study the function of TaADH genes and to determine the candidate gene for wheat stress resistance breeding.

Genome-wide transcriptome analysis using RNA-Seq of Lilium longiflorum revealed valuable genes responding to biotic stresses. WRKY transcription factors are regulatory proteins playing essential roles in defense processes under environmental stresses, causing considerable losses in flower quality and production. Thirty-eight WRKY genes were identified from the transcriptomic profile from lily genotypes, exhibiting leaf blight caused by Botrytis elliptica. Lily WRKYs have a highly conserved motif, WRKYGQK, with a common variant, WRKYGKK. Phylogeny of LlWRKYs with homologous genes from other representative plant species classified them into three groups- I, II, and III consisting of seven, 22, and nine genes, respectively. Base on functional annotation, 22 LlWRKY genes were associated with biotic stress, nine with abiotic stress, and seven with others. Sixteen unique LlWRKY were studied to investigate responses to stress conditions using gene expression under biotic and abiotic stress treatments. Five genes—LlWRKY3, LlWRKY4, LlWRKY5, LlWRKY10, and LlWRKY12—were substantially upregulated, proving to be biotic stress-responsive genes in vivo and in vitro conditions. Moreover, the expression patterns of LlWRKY genes varied in response to drought, heat, cold, and different developmental stages or tissues. Overall, our study provides structural and molecular insights into LlWRKY genes for use in the genetic engineering in Lilium against Botrytis disease.

The calcineurin B-like protein (CBL) and CBL-interacting protein kinase (CIPK) play important roles in plant signal transduction and response to abiotic stress. Plants of Medicago genus contain many important forages, and their growth is often affected by a variety of abiotic stresses. However, studies on the CBL and CIPK family member and their function are rare in Medicago. In this study, a total of 23 CBL and 58 CIPK genes were identified from the genome of Medicago sativa as an important forage crop, and Medicaog truncatula as the model plant. Phylogenetic analysis suggested that these CBL and CIPK genes could be classified into five and seven groups, respectively. Moreover, these genes/proteins showed diverse exon-intron organizations, architectures of conserved protein motifs. Many stress-related cis-acting elements were found in their promoter region. In addition, transcriptional analyses showed that these CBL and CIPK genes exhibited distinct expression patterns in various tissues, and in response to drought, salt, and abscisic acid treatments. In particular, the expression levels of MtCIPK2 (MsCIPK3), MtCIPK17 (MsCIPK11), and MtCIPK18 (MsCIPK12) were significantly increased under PEG, NaCl, and ABA treatments. Collectively, our study suggested that CBL and CIPK genes play crucial roles in response to various abiotic stresses in Medicago.

Abstract Background The Raffinose synthetase (RAFS) genes superfamily is critical for the synthesis of raffinose, which accumulates in plant leaves under abiotic stress. However, it remains unclear whether RAFS contributes to resistance to abiotic stress in plants, specifically in the Gossypium species. Results In this study, we identified 74 RAFS genes from G. hirsutum, G. barbadense, G. arboreum and G. raimondii by using a series of bioinformatic methods. Phylogenetic analysis showed that the RAFS gene family in the four Gossypium species could be divided into four major clades; the relatively uniform distribution of the gene number in each species ranged from 12 to 25 based on species ploidy, most likely resulting from an ancient whole-genome polyploidization. Gene motif analysis showed that the RAFS gene structure was relatively conservative. Promoter analysis for cis-regulatory elements showed that some RAFS genes might be regulated by gibberellins and abscisic acid, which might influence their expression levels. Moreover, we further examined the functions of RAFS under cold, heat, salt and drought stress conditions, based on the expression profile and co-expression network of RAFS genes in Gossypium species. Transcriptome analysis suggested that RAFS genes in clade III are highly expressed in organs such as seed, root, cotyledon, ovule and fiber, and under abiotic stress in particular, indicating the involvement of genes belonging to clade III in resistance to abiotic stress. Gene co-expressed network analysis showed that GhRFS2A-GhRFS6A, GhRFS6D, GhRFS7D and GhRFS8A-GhRFS11A were key genes, with high expression levels under salt, drought, cold and heat stress. Conclusion The findings may provide insights into the evolutionary relationships and expression patterns of RAFS genes in Gossypium species and a theoretical basis for the identification of stress resistance materials in cotton.
