玉米CBL基因的生物信息学分析

Bioinformatics Analysis on Maize CBL Genes

利用生物信息学方法从玉米的基因组中鉴定出10个CBL基因,并对这些基因的染色体分布、进化、蛋白基序、顺式反应元件进行了系统分析。结果表明,玉米的CBL基因分为3个不同的进化类群,在基因组中的分布是不均匀的,而且都含有响应逆境信号的不同顺式反应元件。玉米CBL基因预测编码的蛋白都含有3个EF-手型结构,而且被预测定位在不同的细胞组分中。说明它们可能参与玉米的逆境响应过程,而且在功能上各不相同。

Plant CBL genes play very important roles in environmental stress response.Using bioinformatic method,ten CBL genes were identified from maize genome.Complete analysis of their chromosome distribution,phy-logeny,conserved protein motifs,and cis-acting elements was conducted.The results showed that the maize CBL genes were clustered into three different groups,and they were unevenly distributed in maize genome.They also con-tained different cis-acting elements responsive to environmental stress and hormone s...
