abstract = {* Barley (Hordeum vulgare) is a host for Blumeria graminis
f. sp. hordei (Bgh), which causes powdery mildew, and for
the rice blast pathogen Magnaporthe oryzae. It has
previously been shown that Rar1, initially identified in a
mutational screen as being required for Mla12-specified
Bgh-resistance, also controlled pathogenic growth of M.
oryzae in barley. Here, we tested whether the rom1 mutation
(restoration of Mla12-specified resistance), which restored
resistance against Bgh in a susceptible rar1-2 genetic
background, also influences the interaction between barley
and M. oryzae. * Disease severity after infection with M.
oryzae was analysed on rar1-2 mutants and rar1-2 rom1 double
mutants. Microscopy and northern analysis were used to gain
insight into cellular and molecular events. * On rar1-2 rom1
double mutant plants, the number of M. oryzae disease
lesions was increased in comparison to the wild-type and the
rar1-2 mutant which correlated with augmented epidermal
penetration. However, a decrease in the lesion diameter,
apparently conditioned in the mesophyll, was also observed.
* These results highlight the impact of Rom1 in basal
defence of barley against different pathogens. Importantly,
a tissue-specific function for Rom1 with contrasting effects
on epidermal and mesophyll defence was demonstrated.},
