Bioinformatics Identification and Analysis of GSK3 Gene Family in Maize

摘要(Abstract):

为了揭示玉米糖原合成酶激酶-3(GSK3)家族在玉米生命活动和逆境响应中的作用,利用生物信息学方法对玉米GSK3基因家族成员进行鉴定和分析。结果表明,在玉米全基因组中共鉴定到12个ZmGSK3基因,不均匀地分布在玉米的8条染色体上,蛋白长度为403~473个氨基酸,分子质量为45.17~53.02 kDa,等电点为6.79~8.90,预测亚细胞定位位于细胞质、线粒体和细胞核中;系统进化树分析将ZmGSK3分为4组进化分支,不同分支成员可能功能冗余;ZmGSK3共有10个保守基序,前9个保守基序最为保守,以串联形式存在于GSK3家族成员中,保守基序10仅存在于第I、Ⅲ组成员中;启动子分析显示ZmGSK3基因含有大量光响应、激素响应、胁迫响应相关元件及部分细胞分化相关元件,说明ZmGSK3基因家族可能在玉米光合作用或光形态建成、激素响应、胁迫响应、细胞分化等方面发挥作用。
