Abstract

The study of cereal albumins and globulins has lagged somewhat behind that of the prolamins, which nave been considered as typical reserve proteins. However, these protein fractions merit closer attention for a variety of reasons. The main individual albumins and globulins are at least as abundant as many prolamin components, and it can be speculated that in a tissue, such as the cereal endosperm, which is completely consumed during germination, al 1 abundant proteins may play a reserve role. They have also a higher proportion of essential amino acids, as compared with the prolamins, and thus may be releyant in connec^ tion with the genetic alteration of overall grain composition. Finally, a high proportion of the main components of these protein fractions have inhibitory and even toxic properties, which may be related to the protection of this tissue during development and germination, and might influence the nutritional valué of the cereal products. We report here the characterization in barley of cDNA clones encoding two major groups of proteins: the CM-proteins, a family that inciudes inhibitors of trypsin and a-amylase, and the thionins, a group of high-lysine toxic polypeptides.
