Abstract:

Based on the whole genome data of tea plant(Camellia sinensis), members of tea plant TATA element modulatory factor(CsTMF)gene family were screened and identified. The full-length coding sequence(CDS)of CsTMFs in the tea plant leaves was further cloned. The conserved domain, gene structure, physical and chemical properties, protein secondary structure and phylogenetic relationship of CsTMFs were analyzed by bioinformatics method. Tissue-specific expression was analyzed based on transcriptome data, and qPCR was used to detect the expressions of CsTMFs in the tea plant leaves under cold stress and drought stress. The result showed that there were two genes of CsTMF gene family in the tea plant. The lengths of CDS region in two CsTMF genes were 2 934 bp and 2 904 bp, respectively. There were complete conserved domains, TMF-DNA-bd and TMF-TATA-bd in both two CsTMF genes. CsTMF1 and CsTMF2 had tissue expression specificity. CsTMF1 was highly expressed in the flowers and stems, while CsTMF2 was highly expressed in the mature leaves and stems. The results of qPCR showed that CsTMF1 was induced by cold stress, while CsTMF2 was inhibited by cold stress and drought stress.
