摘　　要：YABBY基因家族是仅存在于植物中的一类含有C2C2锌指结构域和YABBY结构域的转录调控因子,与植物的形态发育有关,在植物的茎、叶和花等器官的生长发育过程中起到重要的调控作用。本研究通过对毛果杨(Populus trichocarpa)YABBY基因家族生物信息学分析,共筛选出12个YABBY家族成员,分别位于第1、2、3、6、8、9、10、14、16和18号染色体。这些成员结构域保守,且具有低亲水性的特点。通过亚细胞定位预测,所有成员都定位在细胞核中。基因组织表达分析表明,毛果杨YABBY家族成员在不同组织中的表达有明显不同,在雌花、雄花和芽中表达量较高。YABBY gene family is a kind of transcription factor that contains C2C2 zinc finger domain and YABBY domain,which is related to plant morphological development and plays an important regulatory role in the development of plant organs such as leaves and flowers.In this study,through bioinformatics analysis of YABBY gene family of Populus trichocarpa,a total of 12 YABBY family members are screened out,which are distributed on chromosomes 1,2,3,6,8,9,10,14,16 and 18.These members are characterized by low hydrophilicity and conserved domains.By cell localization prediction,all the members are located in the nucleus.Functional prediction showed that all family members had multicellular developmental functions and played an important role in regulating the development of fruit,terminal bud,leaf,ovule,carpel and other parts.
