Induction and Mutation Mechanism of Plant Lesion Mimic Mutants

Abstract: Plant lesion mimic mutants develop spontaneous lesions that resemble disease symptoms in the absence of pathogen and stress attack. The mutated genes of the lesion mimic mutation have been shown to involve in programmed cell death， which leads to enhanced disease resistance to multiple pathogens. Therefore， the research on plant lesion mimic mutants plays an important role in revealing the mechanisms of disease resistance response and enhancing the resistance spectrum of plant. The paper briefly reviewed the induction of lesion mimic mutants in plants， molecular mapping and cloning of mutated genes and the mechanism of lesion phenotype formation， which can provide the interest information for the research on the mechanisms of programmed cell death and plant disease resistance.
