Penetration and post-penetration resistance to Magnaporthe oryzae in Arabidopsis.
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.
