Profiling of gene expression in rice in response to inoculation with Magnaporthe oryzae and Xanthomonas oryzae.

Abstract

Rice plants respond to various stimuli including pathogen attack. To understand responses of rice to pathogen infection, we analyzed the expression of genes or rice inoculated with M. oryzae and X. oryzae by using rice 44k oligoarray. In blast-inoculated rice leaves, most drastic changes in gene expression in incompatible rice were observed at 3 days post inoculation. We compared the gene expression profiles in rice inoculated with wild type of X. oryzae with hrcV mutant, which is deficient in type III secretion machinery. Detailed results of these analysis will be reported.
