SQUAMOSA promoter-binding protein-like () gene family, a group of plant-specific transcription factors, played crucial roles in regulating plant growth, development, signal transduction, and stress response. This study focuses on the gene family in the fast-growing , employing bioinformatics approaches to identify and analyze the gene physiochemical characteristics, conserved domains, structural composition, chromosomal distribution, phylogenetic relationships, cis-acting elements, and their expression patterns in various tissues and stress treatments. Twenty-three genes were identified in , which uneven distributed across seven chromosomes and classified into five groups. Prediction of cis-acting elements revealed that these genes might be related to light, hormone, and stress responses. Furthermore, and , mainly expressed in the stem apex and lateral branches, seem to be involved in hormone stress resistance. Our study provides insights into the potential functions of the genes in plant growth, stress response, and hormone transduction, offering valuable perspectives for subsequent research into their biological roles.
SQUAMOSA启动子结合蛋白样（）基因家族是一组植物特有的转录因子，在调节植物生长、发育、信号转导和应激反应中发挥着关键作用。本研究聚焦于速生的基因家族，采用生物信息学方法来鉴定和分析该基因的理化特性、保守结构域、结构组成、染色体分布、系统发育关系、顺式作用元件及其在各种组织和应激处理中的表达模式。在中鉴定出23个基因，它们不均匀地分布在7条染色体上并分为5组。顺式作用元件预测表明这些基因可能与光、激素和应激反应有关。此外，和主要在茎尖和侧枝中表达，似乎参与激素应激抗性。我们的研究为基因在植物生长、应激反应和激素转导中的潜在功能提供了见解，为后续研究它们的生物学作用提供了有价值的观点。
