Abstract: Photosynthesis of plants depends on the green leaves, and the most intuitive feature of leaf growth and development is its color. At present, more than 200 genes related to rice leaf color have been cloned. The regulatory mechanisms of rice leaf color are complex and diverse, which involve multiple regulatory pathways, including biosynthesis and degradation of photosynthetic pigments, pathway of nucleus-plastid signaling, and heme synthesis. In addition, external environment such as temperature and light intensity can also affect the color changes of rice leaves. Here we reviewed the molecular pathways of rice leaf color, environmental factors and leaf color related genes, as well as the genetic regulatory mechanisms of rice leaf color was revealed, which will provide theoretical basis for rice high photosynthetic breeding and application, and future research in addressing some scientific problems in this field.
