摘要
水稻灌浆期叶片光合产物和花前茎鞘储存的非结构性碳水化合物以蔗糖的形式向穗转运,是籽粒灌浆的物质来源。韧皮部装载是水稻叶片和茎鞘蔗糖向籽粒转运的第一个关键步骤。增强韧皮部装载有利于促进叶片和茎鞘蔗糖向籽粒高效转运,是提高水稻产量的重要途径。本文重点综述了水稻蔗糖韧皮部装载策略、生理过程和关键蔗糖载体蛋白的基因表达及调控等研究进展,并探讨了其与水稻产量形成的关系。
Yield formation of rice depend on sucrose that produced in,and translocated from photosynthetically active leaves and stems with non-structural carbohydrates stored prior to heading.Phloem loading of sucrose is the first crucial step for transporting of sucrose to grains.Enhancing phloem loading is beneficial for improving the translocation of sucrose from leaves and stems to grains,which is important way for increasing rice yield.This article reviews the research advances in strategies of phloem loading,physiological process and gene expressions of key sucrose transporters in rice,and we discuss the relationship of sucrose phloem loading with grain yield formation in rice.
