Interpretive Summary:

Technical Abstract: This review article describes the cellular and molecular biology of proteins stored in seed cotyledons. The first two chapters define the storage globulins (7S and 11S) and storage albumins (2S) that together account for the majority of proteins accumulated in cotyledons. These proteins have no known enzymatic activity. The chapters that follow describe a number of other families of seed proteins that do have enzymatic activity. The examples described include protease inhibitors, storage lectins other miscellaneous proteins that account for sizable seed reserves. The objective of the review is to describe the key features of the genes that encode these proteins, the genetic linkage relationships among them, and what is known about developmental processes that regulate the appearance of proteins the genes encode. The complex and poorly understood mechanisms by which storage proteins move from endoplasmic reticulum where they are synthesized through the secretory system to protein storage vacuoles where they are deposited, and their assembly therein, are described. Information about the structure of the proteins is reviewed, and potential evolutionary relationships to progenator proteins are identified. The chapter will be published together with a number of others on related topics about agronomically legumes and cereals.
