Oat polysomes direct the synthesisin vitro of a large number of products, the majority of which are the salt-soluble globulins (1,3,10,11,21). Total RNA or poly A+ RNA isolated from these polysomes directs the synthesis of the same number and types of products; however, the amount of
globulins synthesized no longer represents the major products; rather, there is a decreased level of globulins and an increased
amount of the other products synthesizedin vitro (6, 18). These results imply that the translational control can dictate final product levels. Reconstruction experiments
using oat poly A+ mRNA and polysomal factors that are made free of endogenous RNA by nuclease digestion demonstrate that these factors do influence
the translational specificity of oat globulin mRNA relative to other mRNAs. It is suggested that translational control is
partially responsible for the levels of globulin in the mature grain. 相似文献
