The formation of rice lesion mimic was affected by gene mutation, metabolic disorder, accumulation of active oxygen, hormone imbalance, blocked ion channels, out of control programmed cell death process, abiotic stress and so on. The process of disease was usually accompanied by the improvement of plant resistance, and the expression of defense system related genes increases. At present, the study of disease-like mutants mainly focused on the mapping, cloning and functional analysis of mutant genes. The mechanism of rice lesion mimic mutants was reviewed, especially the location, coding and function of the cloned disease like genes In this paper. The mechanism of programmed cell death in rice disease like cells was summarized, and the prospect of disease like mutants and rice breeding practice was put forward. It was of great significance to further analyze the regulatory mechanism of defense response and breeding application of rice lesion mimic mutant gene.
