利用修饰光敏色素信号途径进行作物改良的可行性
A New Strategy for Crop Improvement Through Modification of Phytochrome Signaling Pathways
摘要
Abstract
In this review, the mechanisms of photomorphogenesis regulated by phytochromes and the regulatory effects of phytochrome family members on morphogenesis in the model plant Arabidopsis were introduced. The phytochorme signaling pathways in gramineous plants and progress in research related to the yield traits and mutant discoveries were sumarized. Overexpression and/or loss-of-fuction mutants of phytochromes in wheat and maize lead to significant variations in plant height, flowering time and shade avoidance responses. Genetics, biochemical and molecular analyses on these variations related to yield traits will help us develop new strategies for crop improvement through the modification of light signaling pathways.关键词
