摘　要：

磷酸盐是植物生长、发育、繁殖不可缺少的因子。然而在自然和农业环境中, 植物可利用的磷酸盐极为低下, 从而 提高植物对磷酸盐的利用率至关重要。本文结合近年来国内外的相关研究, 就缺磷环境下植物体内相应的信号分子及其 相互作用机制进行了阐述。

Abstract:

Phosphate (Pi) is an important factor to plant growth, development and productivity. The soluble Pi to plant in soil is extremely low because of biochemical fixation in both natural and agricultural ecosystems. Improving plant with efficient Pi utilization is an important breeding strategy for sustaibable agriculture. In this paper, the recent research progress in Pi-starvation signaling and its cross-talks with phytohormones in plants is reviewed.

Key words: phosphate; signaling; SPX; phytohormones
