The FK506 Binding Protein (FKBP), ubiquitously present across diverse species, is characterized by its evolutionarily conserved FK506 binding domain (FKBd). In plants, evidence suggests that this gene family plays integral roles in regulating growth, development, and responses to environmental stresses. Notably, research on the identification and functionality of genes in rice remains limited. Therefore, this study utilized bioinformatic tools to identify 30 -encoding genes in rice. It provides a detailed analysis of their chromosomal locations, evolutionary relationships with the FKBP family, and gene structures. Further analysis of the promoter elements of these rice genes revealed a high presence of stress-responsive elements. Quantitative PCR assays under drought and heat stress conditions demonstrated that genes , , , , and are inducible by these adverse conditions. These findings suggest a significant role for the rice gene family in stress adaptation. This research establishes a critical foundation for deeper explorations of the functional roles of the genes in rice.
FK506 结合蛋白（FKBP）广泛存在于各种物种中，其特征是具有进化上保守的 FK506 结合结构域（FKBd）。在植物中，有证据表明这个基因家族在调节生长、发育和对环境胁迫的反应中起着重要作用。值得注意的是，关于水稻中基因的鉴定和功能的研究仍然有限。因此，本研究利用生物信息学工具在水稻中鉴定出 30 个编码基因。它详细分析了它们的染色体位置、与 FKBP 家族的进化关系以及基因结构。对这些水稻基因启动子元件的进一步分析表明，存在大量的应激响应元件。干旱和热胁迫条件下的定量 PCR 分析表明，基因 、 、 、 和 在这些不利条件下是诱导表达的。这些发现表明水稻基因家族在应激适应中起着重要作用。本研究为深入探索水稻 基因在功能中的作用奠定了重要基础。
