[PMID: 36138347 PMCID: PMC9502961 DOI: 10.1186/s12864-022-08894-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Accepted: 09/16/2022] [Indexed: 11/12/2022] Open
Abstract
Background As a type of calmodulin binding protein, CAMTAs are widely involved in vegetative and reproductive processes as well as various hormonal and stress responses in plants. To study the functions of CAMTA genes in tea plants, we investigated bioinformatics analysis and performed qRT-PCR analysis of the CAMTA gene family by using the genomes of ‘ShuChaZao’ tea plant cultivar. Results In this study, 6 CsCAMTAs were identified from tea plant genome. Bioinformatics analysis results showed that all CsCAMTAs contained six highly conserved functional domains. Tissue-specific analysis results found that CsCAMTAs played great roles in mediating tea plant aging and flowering periods. Under hormone and abiotic stress conditions, most CsCAMTAs were upregulated at different time points under different treatment conditions. In addition, the expression levels of CsCAMTA1/3/4/6 were higher in cold-resistant cultivar ‘LongJing43’ than in the cold-susceptible cultivar ‘DaMianBai’ at cold acclimation stage, while CsCAMTA2/5 showed higher expression levels in ‘DaMianBai’ than in ‘LongJing43’ during entire cold acclimation periods. Conclusions In brief, the present results revealed that CsCAMTAs played great roles in tea plant growth, development and stress responses, which laid the foundation for deeply exploring their molecular regulation mechanisms.

Yao Y, Zhao H, Sun L, Wu W, Li C, Wu Q. Genome-wide identification of MAPK gene family members in Fagopyrum tataricum and their expression during development and stress responses. BMC Genomics 2022; 23:96. [PMID: 35114949 PMCID: PMC8815160 DOI: 10.1186/s12864-022-08293-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Accepted: 01/03/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Mitogen-activated protein kinases (MAPKs) plays essential roles in the development, hormone regulation and abiotic stress response of plants. Nevertheless, a comprehensive study on MAPK family members has thus far not been performed in Tartary buckwheat. RESULTS Here, we identified 16 FtMAPKs in the Fagopyrum tataricum genome. Phylogenetic analysis showed that the FtMAPK family members could be classified into Groups A, B, C and D, in which A, B and C members contain a Thr-Glu-Tyr (TEY) signature motif and Group D members contain a Thr-Asp-Tyr (TDY) signature motif. Promoter cis-acting elements showed that most ProFtMAPks contain light response elements, hormone response elements and abiotic stress response elements, and several ProFtMAPks have MYB-binding sites, which may be involved in the regulation of flavonoid biosynthesis-related enzyme gene expression. Synteny analysis indicated that FtMAPKs have a variety of biological functions. Protein interaction prediction suggested that MAPKs can interact with proteins involved in development and stress resistance. Correlation analysis further confirmed that most of the FtMAPK genes and transcription factors involved in the stress response have the same expression pattern. The transient transformation of FtMAPK1 significantly increased the antioxidant enzymes activity in Tartary buckwheat leaves. In addition, we also found that FtMAPK1 can respond to salt stress by up-regulating the transcription abundance of downstream genes. CONCLUSIONS A total of 16 MAPKs were identified in Tartary buckwheat, and the members of the MAPK family containing the TDY motif were found to have expanded. The same subfamily members have relatively conserved gene structures and similar protein motifs. Tissue-specific expression indicated that the expression of all FtMAPK genes varied widely in the roots, stems, leaves and flowers. Most FtMAPKs can regulate the expression of other transcription factors and participate in the abiotic stress response. Our findings comprehensively revealed the FtMAPK gene family and laid a theoretical foundation for the functional characterization of FtMAPKs.
