Regions of the Cf-9B Disease Resistance Protein Able to Cause Spontaneous Necrosis in Nicotiana benthamiana Lie Within the Region Controlling Pathogen Recognition in Tomato

Chakrabarti, Apratim; Panter, Steven; Harrison, K; Jones, Jonathan D G; Jones, David


The tomato Cf-9 and Cf-9B genes both confer resistance to the leaf mold fungus Cladosporium fulvum but only Cf-9 confers seedling resistance and recognizes the avirulence (Avr) protein Avr9 produced by C. fulvum. Using domain swaps, leucine-rich repeats (LRR) 5 to 15 of Cf-9 were shown to be required for Cf-9-specific resistance to C. fulvum in tomato, and the entire N-terminus up to LRR15 of Cf-9B was shown to be required for Cf-9B-specific resistance. Finer domain swaps showed that nine...[Show more]
