The new green revolution is looking for a breakthrough in the world. Constructing C4 rice based on good plant type is a reliable and effective approach to enhance photosynthetic efficiency in leaf. The paper discusses the significance, techniques, physiological characteristics and future research directions of transgenic rice with C4 gene and makes some suggestions on breeding new cultivars with super-high yield and photosynthetic efficiency in high light intensity and high temperature area of China, especially in Africa.
Key words: Rice, C4 photosynthesis gene, photosynthesis, physiological breeding.
