Inhibition of resistance gene-mediated defense in rice by Xanthomonas oryzae pv. oryzicola.
Mol Plant Microbe Interact 2006; 19(3):240-9MP

Abstract

Xanthomonas oryzae pv. oryzae and the closely related X. oryzae pv. oryzicola cause bacterial blight and bacterial leaf streak of rice, respectively. Although many rice resistance (R) genes and some corresponding avirulence (avr) genes have been characterized for bacterial blight, no endogenous avr/R gene interactions have been identified for leaf streak. Genes avrXa7 and avrXa10 from X. oryzae pv. oryzae failed to elicit the plant defense-associated hypersensitive reaction (HR) and failed to prevent development of leaf streak in rice cultivars with the corresponding R genes after introduction into X. oryzae pv. oryzicola despite the ability of this pathovar to deliver an AvrXa10:Cya fusion protein into rice cells. Furthermore, coinoculation of X. oryzae pv. oryzicola inhibited the HR of rice cultivar IRBB10 to X. oryzae pv. oryzae carrying avrXa10. Inhibition was quantitative and dependent on the type III secretion system of X. oryzae pv. oryzicola. The results suggest that one or more X. oryzae pv. oryzicola type III effectors interfere with avr/R gene-mediated recognition or signaling and subsequent defense response in the host. Inhibition of R gene-mediated defense by X. oryzae pv. oryzicola may explain, in part, the apparent lack of major gene resistance to leaf streak.
