The rate of entry of Magnaporthe oryzae into the Arabidopsis pen2 quintuple (pen2 NahG pmr5 agb1 mlo2) mutant was significantly higher than those into the pen2 quadruple (pen2 NahG pmr5 agb1 and pen2 NahG pmr5 mlo2) mutants. The lengths of the infection hyphae in the pen2 quintuple mutant were intermediate between the pen2 quadruple mutants. These results suggest that different genetic networks, consisting of PEN2, PMR5, AGB1, and MLO2, control penetration and post-penetration resistance to M. oryzae in Arabidopsis.
稻瘟病菌进入拟南芥pen2五重突变体（pen2 NahG pmr5 agb1 mlo2）的速率显著高于进入pen2四重突变体（pen2 NahG pmr5 agb1和pen2 NahG pmr5 mlo2）的速率。pen2五重突变体中侵染菌丝的长度介于pen2四重突变体之间。这些结果表明，由PEN2、PMR5、AGB1和MLO2组成的不同遗传网络控制着拟南芥对稻瘟病菌的穿透和穿透后抗性。
