摘要

SQUAMOSA promoter-binding protein (SBP)-box gene family is one kind of plant-specific transcription factor that plays important roles in the process of resisting abiotic stress. The SBP-box gene family has been studied in many species, but their functions are not yet clear in Camellia sinensis var. sinensis (CSS) (tea) plants. In our study, 25 SBP-box genes in the CSS were identified in the reference genome and classified into six groups based on a phylogenetic tree. The expression pattern of CsSBP genes under temperature stresses showed that CsSBPs were involved in the process of resisting temperature stresses. CsSBP8 had a positive effect on the anthocyanin accumulation during high temperature exposures, but CsSBP12 has a high correlation with anthocyanin accumulation during both high and low temperature. This study provides a foundation for the further study of CsSBP genes involved in the anthocyanin biosynthesis pathway during the temperature stress in tea.
