摘要
YABBY基因家族属于锌指蛋白超家族(Zinc finger super-family)的亚家族,在调控植物叶和花器官发育过程中起着重要的作用。从陆地棉标准系TM-1(Gossypium hirsutum L.acc.TM-1)基因组中鉴定到23个YABBY基因家族成员,具有不同的亚细胞定位;这些基因分布在16条染色体和1条Scaffold上,且有9对共线性基因;棉花的YABBY基因家族分为4个亚组,每个亚组都有与拟南芥同源的基因,且每个亚组成员间具有相似的基序类型和排列顺序;组织表达分析表明,TM-1全基因组中的23个YABBY基因家族成员具有较为广泛的组织表达类型。所有YABBY基因家族成员在花、蕾和茎端分生组织中表达。
The YABBY gene family, as a subfamily of zinc finger super-family, plays a vital role in regulating the development of plant leaf and floral organs. 23 YABBY genes with different subcellular localizations were identified from the genome of upland cotton(Gossypium hirsutumL. acc. TM-1). These 23 YABBY genes distributed on 16 chromosomes and 1 Scaffold, and 9 pairs of them were syntenic genes. The cotton YABBY gene family could be divided into four subfamily groups, and there were homologous genes of Arabidopsis thaliana L. in each group. Furthermore, there were similar motif type and arrangement in each group. The tissue expression analysis showed that the expression pattern of the 23 YABBY genes from TM-1 genome varied among different tissues, and all the YABBY gene family members were expressed in the flower, bud and shoot apical meristem.
