摘要
YABBY转录因子家族广泛参与植物的生长发育,但在单子叶植物的作用机理有待进一步研究。本研究利用生物信息学方法系统分析了水稻YABBY家族成员。保守性分析表明,水稻基因组中共有8个YABBY成员,不均匀地分布在2、3、7、10和12染色体上,成员之间相对保守,分为四个亚族。进化分析表明,片段复制或全基因组复制是YABBY基因在进化过程中的主要扩张方式,且YABBY家族的分化可能晚于单双子叶植物的分化。启动子和表达分析表明,水稻YABBY家族成员可能在水稻的花器官的发育、多中激素的响应中具有重要的作用。本研究为水稻YABBY基因的功能鉴定提供了理论支持和参考依据。
The YABBY family is widely involved in plant growth and development,but the mechanism of YABBY family needs to be further study in monocotyledons.In this study,rice YABBY family was systematically analyzed using bioinformatics method.Conservative analysis showed that 8 YABBY family members in rice genome were unevenly distributed on chromosomes 2,3,7,10,and 12.Furthermore,they were relatively conservative and divided into four subfamilies.Evolutionary analysis indicated that fragment replication or genome-wide replication might be the main reason for expansion of YABBY gene during evolutionary processes.The differentiation of YABBY family might be later than that of monocots and dicots.Promoter and expression analysis indicated that rice YABBY family members might play an important role in floral organs development and response of multiple hormones in rice.Altogether,this study provided valuable information for rice YABBY gene functional identification.
