The promoter binding protein (SBP)-box gene family is a plant-specific transcription factor family. This family plays a crucial role in plant growth and development. In this study, 20 SBP-box genes were identified in the tea plant genome and classified into six groups. The genes in each group shared similar exon-intron structures and motif positions. Expression pattern analyses in five different tissues demonstrated that expression in the buds and leaves was higher than that in other tissues. The -elements and expression patterns of the genes suggested that the genes play active roles in abiotic stress responses; these responses may depend on the abscisic acid (ABA), gibberellic acid (GA), and methyl jasmonate (MeJA) signaling pathways. Our work provides a comprehensive understanding of the family and will aid in genetically improving tea plants.
启动子结合蛋白（SBP）-盒基因家族是一个植物特异性转录因子家族。这个家族在植物生长和发育中起着至关重要的作用。在这项研究中，在茶树基因组中鉴定出 20 个 SBP-盒基因，并将其分为六组。每组基因具有相似的外显子-内含子结构和基序位置。在五个不同组织中的表达模式分析表明，在芽和叶中的表达高于其他组织。基因的 -元件和表达模式表明，基因在非生物胁迫反应中发挥积极作用；这些反应可能依赖于脱落酸（ABA）、赤霉素（GA）和茉莉酸甲酯（MeJA）信号通路。我们的工作提供了对 家族的全面理解，并将有助于茶树的遗传改良。
