| Research Abstract |
We constructed knock-out mutants of seven histone lysine methyltransferase (HMT) genes in the fungus Magnaporthe oryzae. Phenotypic analysis revealed that one of the HMT genes, MoHMT4, which catalyzes methylation of histone H3 lysine 4, had the greatest impact on pathogenicity-related morphogenesis, signal perception and virulence. ChIP-seq analysis was performed to reveal the genome-wide changes of H3K4 methylation during infection of M. oryzae.
