YABBY基因家族作为植物特有的转录因子家族,在调控植物侧生器官发育中发挥重要作用.本研究利用玉米全基因组数据分析玉米YABBY基因家族,阐明该基因家族成员结构、系统进化发育关系以及基因家族成员在玉米不同组织及不同发育时期的表达谱.结果显示,玉米参考基因组中存在13个YABBY基因,命名为ZmY-ABBY1~ZmYABBY13,根据系统发育关系和序列相似性将该基因家族分为4亚类S1~S4. RNAseq数据显示玉米YABBY基因在籽粒、茎和茎端分生组织( Shoot apica1 meristem,SAM)、幼胚及叶片中有较高表达,预示玉米YABBY基因可能在上述器官发育中发挥调控作用.本研究结果为进一步解析该基因家族的功能奠定了研究基础.

YABBY gene fami1y, as a group of p1ant-specific transcription factors, is invo1ved in the deve1opment of 1atera1 organs in p1ants. Based on maize V3 genome sequence, a genome-wide overview of gene fami1y in maize was presen-ted, inc1uding the gene structures, phy1ogeny, and mRNA expression at1as in 18 different deve1opment stages. The ana1y-ses have revea1ed 13 YABBY genes existing in maize genome, named ZmYABBY1-ZmYABBY13. According to the phy1oge-netic re1ationships and sequence simi1arity, the gene fami1y was divided into 4 subgroups (S1-S4). YABBY gene expres-sion profi1ing ana1ysis showed that some genes were high1y expressed in deve1oping seed, stem and shoot apica1 meristem ( SAM) , embryo and 1eaf, suggesting YABBY genes may p1ay an positive ro1e in the deve1opment of these tissues. The pre-1iminary genomics ana1ysis 1ays a foundation for future functiona1 dissection of YABBY fami1y gene.
