摘要:
为了探明分离自芒果的胶孢炭疽菌(Colletotrichum gloeosporioides)漆酶同工酶基因的序列特征,进一步研究该菌的分子致病机理。以该菌为材料,采用同源克隆和RT-PCR法获得胶孢炭疽菌漆酶基因Lac2(KF924625)。结果表明,其编码区大小为1 785 bp,编码594个氨基酸,分子量为65.53 ku,等电点是6.56,含4个铜离子结合保守结构域;聚类分析发现,其预测蛋白与西瓜炭疽病菌(Colletotrichum orbiculare)的漆酶laccase-1(ENH77191.1)同源性最高,达到79%;半定量RT-PCR分析表明,在分生孢子不同萌发时段,Lac2的表达量有明显的升降趋势,接种后6 h表达量最低,9 h最高。可见Lac2具备真菌漆酶基因家族的序列特征,初步推测它可能与C. gloeosporioides分生孢子萌发侵染寄主有关,也可能参与调控芒果胶孢炭疽菌的漆酶活性和抗氧化反应等。
