| Abstract: | Early leaf senescence greatly affects grain yield and quality in rice. Studies on the agronomic and physiological traits of the early leaf senescence mutants in rice would be beneficial to understanding the senescence process and its underlying mechanism in plants. We briefly summarized the characteristics and mechanisms of early leaf senescence, with focus on reviewing the agronomic and physiological traits of early leaf senescence mutants in rice and the regulation ways of delaying leaf senescence. Such a review would lay a theoretical basis for the breeding of anti-aging varieties and optimized cultivation practice in rice. |
