Figure 8. Defense-related gene expression induced by MoHrip1 in rice leaves.

PR genes were induced and their expression persisted for days in M. oryzae strain RO1-1-treated plants and in MoHrip1-pretreated plants that were not exposed to M. oryzae strain RO1-1. In contrast, the expression of PR genes was induced after 2 days of treatment and declined thereafter in the RO1-1-treated samples. The error bars represent ± SD of the mean. Essentially identical results were obtained in three independent experiments. A. Expression of OsPR-1a induced by MoHrip1 in rice leaves, B. Expression of OsPR-10a induced by MoHrip1 in rice leaves.
