Identification of Two Genes Required in Tomato for Full Cf-9-Dependent Resistance to Cladosporium fulvum



Identification of Two Genes Required in Tomato for Full Cf-9-Dependent Resistance to Cladosporium fulvum



Plant Cell 6(3): 361-374



Mutagenesis was used to identify and characterize plant genes required for fungal disease resistance gene function in tomato. Seed of a stock homozygous for the Cf-9 gene for resistance to Cladosporium fulvum were treated with ethyl methanesulfonate, and 568 M2 families were screened for mutations to C. fulvum sensitivity. Eight mutants with reduced resistance were isolated. Four mutations, all of which mapped to the Cf-9 gene, lost both resistance and response to the race-specific AVR9 elicitor. The other four mutations partially lost resistance and response to the AVR9 elicitor. Cytological analysis revealed that a unique host cell staining pattern accompanied the reduced-resistance phenotype in three mutants. Two of the mutants with reduced resistance mapped to Cf-9, and two mapped to two distinct loci designated Rcr-1 and Rcr-2 (Required for Cladosporium resistance) that are unlinked to Cf-9.
