摘　　要：探索毛果杨SRS基因家族的结构功能.利用生物信息学方法分析毛果杨SRS基因家族蛋白理化性质、启动子顺式作用元件、基因结构与保守序列.研究结果表明,PtSRS基因家族成员4个分支(A1~A4),所有成员均含有内含子及外显子;9条染色体中定位有PtSRS基因;大部分成员预测到防御、应激反应顺式作用元件(TC-richrepeats)以及脱落酸响应元件(ABRE).PtSRS基因家族在毛果杨的激素调控和抗逆反应方面发挥着重要作用.The structural and functional exploration of the Populus trichocarpa SRS gene family was conducted.Using bioinformatics approaches,the physicochemical properties of the PtsSRS family proteins,promoter cis-regulatory elements,gene structure,and conserved sequences were analyzed.The results indicated that the PtSRS gene family consists of four branches(A1~A4),with all members containing both introns and exons.The genes were mapped to nine chromosomes in the Populus trichocarpa genome.Additionally,most of the members were predicted to contain cis-regulatory elements related to defense and stress responses,such as TC-rich repeats and ABA-responsive elements(ABRE).The PtSRS gene family plays a crucial role in hormone regulation and stress response in Populus trichocarpa.
