玉米CBL基因的生物信息学分析

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。

Bioinformatics Analysis on Maize CBL Genes

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, phylogeny, 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 contained different cis-acting elements responsive to environmental stress and hormone signals. The putative CBL proteins of maize all had three EF-hands and they were predicted to localize into different sub-cellular compartments. These results suggested that maize CBL genes may involve in stress response and hormone signaling, and their biological functions were divergent.
