Regulation of Nitrogen Metabolism During Early Seedling Growth

  • Chapter
Mobilization of Reserves in Germination

Part of the book series: Recent Advances in Phytochemistry ((RAPT,volume 17))

Abstract

During grain development the basic storage reserves, (carbohydrates, lipids, and proteins) are laid down in all parts of the grain or seed. After germination hydrolysis of these reserves is seen first in the seedling, subsequently in the cotyledon or scutellum and finally, in the endosperm.1,2 The carbohydrate, whether stored initially or derived from lipids,3 is available as a substrate to supply the energy and reducing power as well as the building blocks required for the formation of new cells (Fig. 1). One place where metabolism involved in the reworking of carbon is potentially regulated is in the reutilization of the amino acids supplied by the hydrolysis of storage proteins.
