Abstract excerpt

We used rice dwarf1 (d1) mutants lacking a single-copy Galpha gene and addressed Galpha's role in disease resistance. d1 mutants exhibited a highly reduced hypersensitive response to infection by an avirulent race of rice blast. Activation of PR gene expression in the leaves of the mutants infected with rice blast was delayed for 24 h relative to the wild type. H(2)O(2) production and PR gene expression induced...
