Nucleoside Diphosphate Levels in Taproots and Fibrous Roots of Beta vulgaris L. : Implifications for Control of Sucrose Allocation between Two Sinks.

abstract：:Oilseeds are the main source of lipids used in both food and biofuels. The growing demand for vegetable oil has focused research toward increasing the amount of this valuable component in oilseed crops. Globally, soybean (Glycine max) is one of the most important oilseed crops grown, contributing about 30% of the vege...
