摘　　要：PEX11基因家族成员是参与过氧化物酶体增殖调控的关键因子。在玉米大斑病菌基因组中鉴定出2个PEX11基因,根据其相对分子质量分别命名为StPEX11-1和StPEX11-2。利用生物信息学方法,对基因结构、蛋白质的保守结构域及理化性质进行分析,预测其二级结构域。系统发育树分析发现,玉米大斑病菌的2个StPEX11基因分别属于I型和III型的PEX11亚家族。PEX11 gene family members are key factors which are involved in the regulation of peroxisome pro-liferation. Two PEX11 genes that named StPEX11-1 and StPEX11-2 were identified in this study. Based on theirmolecular weight in Setosphaeriaturcica genome and bioinformatics methods was used to analyze the gene structure,conserved domains, physical and chemical properties and predictthe secondary structure. Furthermore, phylogenet-ictree analysis revealed that the two genes belong to the type I and type III of PEX11 in fungi, respectively.
