Identification of the cir1 disease resistance gene in Arabidopsis thaliana

Plants rely on an elaborate multi-layered defence system to perceive and effectively respond to disease causing pathogens. The defence-related cir1 (constitutively induced resistance 1) mutant was first isolated in an effort to identify components of the Arabidopsis thaliana defence system essential for resistance against pathogens. The cir1 mutant has previously been described as having increased resistance to the virulent bacterial pathogen Pseudomonas syringae pv. tomato DC3000 and oomycete pathogen Hyaloperonospora parasitica Noco2 and was shown to constitutively express salicyclic acid-, jasmonic acid/ethylene- and reactive oxygen intermediate-responsive genes. Genetic analysis and mapping studies of the mutation revealed that it is recessive and may be encoded by one of eight genes located within a 309.10 kb region on the lower arm of chromosome four.
