Rice bacterial blight, caused by Xanthomonasoryzae pv. Oryzae (Xoo), is one of the most serious rice diseases worldwide. The bacterial blight resistance trait from Oryza meyeriana, a wild rice species, was introduced into an elite japonica rice cultivar using asymmetric somatic hybridization. This study was carried out with the intention of understanding the molecular mechanism of incompatible interaction between Xoo and the stable somatic hybrids by using proteomic analyses. Proteins were extracted from leaves at 24, 48, and 72 h after Xoo inoculation and separated by 2-DE. A total of 77 protein spots changed their intensities significantly (p<0.05) by more than 1.5-fold at least at one time point. Sixty-four protein spots were successfully identified by MS analysis. Among them, 51 were known to be involved in photosynthesis. Up-regulation of Rubisco large subunit (RcbL) small fragments and down-regulation of RcbL big fragments indicated that intact RcbL and RcbL big fragments degraded following Xoo attack, which was further confirmed by Western blot analysis. The differential expression of proteins related to signal transduction, antioxidant defense, photosynthesis, metabolism, and protein turnover during the Xoo infection, suggests the existence of a complex regulatory network in the somatic hybrid rice that increases resistance toward Xoo infection and damage. |
