基于水稻粒长OsPPKL1基因的玉米同源基因的生物信息学分析

Bioinformatics Analysis of Orthologous Maize Genes Based on Rice Kernel Length Gene OsPPKL1

为弄清玉米中粒长基因的调控机制,采用生物信息学的方法,对水稻粒长基因OsPPKL1进行同源性分析。结果表明:玉米GRMZM2G070323和GRMZM2G148539基因是OsPPKL1的同源基因,分别位于第1染色体和第5染色体上;这2个基因的基因结构存在一定差异;玉米同源基因与OsPPKL1存在良好的共线性;这2个玉米基因与水稻粒长基因在蛋白质序列、理化性质、高级结构和表达部位等方面均表现出高度的一致性。

To understand the mechanism of maize kernel length gene,based on the bioinformatics analysis,the authors studied the maize genes and their proteins homologous to rice OsPPKL1.The results suggested that the evolution relationship of maize genes GRMZM2G070323（chr 1）and GRMZM2G148539（chr 5）are close to the rice gene;the structures of the two maize genes are different from each other;the gene regions of maize and rice present perfect colinearity;The two maize genes and OsPPKL1 are extremely similar in the aspects of sequence,physical and chemical properties,advanced structure and the express positions.
