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.

SQUAMOSA启动子结合蛋白（SBP）-box基因家族是一种植物特异性转录因子，在抵抗非生物胁迫的过程中起着重要作用。该SBP-盒基因家族进行了研究在许多物种中，但其功能尚未明确茶树变种。中华（CSS）（茶）植物。在我们的研究中，在参考基因组中鉴定出CSS中的25个SBP-box基因，并根据系统树将其分为6组。CsSBP基因在温度胁迫下的表达模式表明，CsSBPs参与了抗温度胁迫的过程。CsSBP8对高温暴露期间的花色苷积累具有积极影响，但CsSBP12与高温和低温期间的花色苷积累高度相关。该研究为进一步研究茶温度胁迫过程中花色苷生物合成途径中涉及的CsSBP基因提供了基础。
