Abstract
The capacity of polyadenylated RNA from developing castor bean endosperm to program protein synthesis in a wheat germ cell-free translational system was examined. Although the use of micrococcal nuclease-treated wheat germ extracts demonstrated a low but significant content of translatable mRNA in dry seeds, a large scale increase in total translational capacity was observed during germination. The cellular content of translatable mRNA peaked on the 4th day of germination and subsequently declined. Protein synthesis in castor bean endosperm cells during germination is directed by newly transcribed mRNA.This publication has 9 references indexed in Scilit:
