Dominant-negative interference with defence signalling by truncation mutations of the tomato Cf-9 disease resistance genes

Barker, Claire; Baillie, Brett; Hammond-Kosack, Kim E; Jones, Jonathan D G; Jones, David


The tomato Cf-9 gene confers resistance to races of the leaf mould fungus Cladosporium fulvum that carry the Avr9 avirulence gene. Cf-9 was isolated by transposon tagging using a modified maize Dissociation (Ds) element. This generated an allelic series of Ds-induced mutations of Cf-9, of which two were found to confer novel phenotypes in a screen for mutants affecting wild-type Cf-9 function in trans. Genetic and molecular analysis of these mutants suggested semidominant, Avr9-dependent,...[Show more]
