Abstract: Chlorophyll is the important pigment participating in photosynthesis in plant chloroplasts. The photosynthetic rate,the output and quality of crops are decided by synthesis of chlorophyll. Synthesis and catabolism of chlorophyll is a complicated process and many genes are involved in this process,in which any gene’s mutation would affect the synthesis and catabolism of chlorophyll and further lead to changing of the leaf colour or affecting the plant growth. The research of leaf colour mutant is an effective approach of verifying the gene function during the development of chloroplast. Therefore,it is of both important theoretical significance and application value to discover and identify the leaf colour mutant genes and to carry out the location,clone and function analysis of the chlorophyll-related genes. This paper reviews the research progresses on rice yellow green leaf mutants,which not only provides the promising materials for researching the chlorophyll biosynthesis pathway and the mechanism of photosynthesis,but also can be used as the marker traits in heterosis.

Key words: rice, yellow green leaf mutants, chloroplast, plant pigment, agronomic trait
