水稻叶色突变体研究进展

Leaf color mutation is a common mutation phenotype of model plants. More than 190 leaf color variation materials have been found in rice, and several genes related to leaf color variation have been cloned, including chlorophyll synthesis, degradation and chloroplast differentiation and development. In this paper, the research progress of rice leaf color mutants was reviewed from the source of leaf color mutants, molecular mechanism of mutation and its application in cross breeding and high light efficiency breeding. Some leaf color genes involved in various metabolic pathways affected by environment were summarized and discussed in order to provide reference for rice molecular design and breeding.
