烤烟烘烤过程淀粉降解与糖分转化途径及调控

Pathway of Starch Breakdown and Sugar Translation in Tobacco Leaves During Flue-curing and Their Regulation

分析并绘制了烤烟烘烤过程淀粉降解与糖分转化的路径,阐明了淀粉在叶绿体内降解的主要产物为麦芽糖,麦芽糖在细胞质内转化合成蔗糖,蔗糖在液泡内转化为葡萄糖和果糖。该路径的阐明为烟叶烘烤过程淀粉降解与糖分转化调控提供了依据。

This paper described the pathway of starch breakdown and sugar translation in tobacco leaves during flue-curing. Maltose is the major form of carbon exported from the chloroplast. Sucrose is madeby sucrose phosphate synthase in the cytosol. The hydrolysis of sucrose yield fructose and glucose in the vacuole. The expound of the pathway provided the basis for regulation of starch breakdown and sugar translation in tobacco leaves during flue-curing.
