Abstract

The enzymic basis for the flow of nitrogen from arginine to asparagine during the first 3 days of germination has been measured in extracts from cotton (Gossypium hirsutum) cotyledons. Evidence that asparagine synthetase regulates asparagine accumulation in germination (for transport to the axis) is presented. Further, evidence that the bulk of the nitrogen passed from one generation to the next in dicots is through an asparagine cycle involving the following sequence asparagine --> arginine --> storage protein --> arginine --> asparagine is discussed.
