摘要: 植物光合作用主要依赖绿色叶片, 而叶片生长发育最直观的特征是叶色。目前已克隆200多个调控水稻(Oryza sativa)叶色的基因。水稻叶色调控机制复杂多样, 涉及多条调控途径, 包括光合色素的生物合成与降解、核-质信号转导和血红素的合成。此外, 温度和光照强度等外部环境也会影响水稻叶色的变化。该文从分子机制、叶色相关基因及环境因素等方面总结了水稻叶色遗传调控机制, 并提出该领域亟待解决的科学问题, 以期为水稻高光效育种及应用提供理论支撑。

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.
