植物中糖与磷信号交互作用的分子机制
Molecular mechanisms underlying the crosstalk between sugar and phosphate signaling in plants
摘要
Abstract
When plants encounter low phosphate stress,they activate a series of adaptive responses to optimize phosphorus absorption and utilization.As products of photosynthesis,sugars not only provide energy for plants but also play critical roles in regulating phosphorus uptake and transport.Sugars enhance phosphorus absorption and participate in plant responses to low phosphate stress by modulating phosphate signaling pathways.This review summarizes the molecular mechanisms underlying the crosstalk between sugar and phosphate signaling,with a focus on how sugars activate phosphate starvation-induced genes,regulate root architecture and hormonal signaling networks,and thereby improve phosphorus absorption and allocation efficiency.These insights aim to advance research on the interaction between sugar and phosphate signaling,facilitating theoretical studies on plant adaptation to low phosphate environments and supporting the breeding of phosphorus-efficient crops.关键词
