Abstract
RNA from 3 plant viruses: potato virus X (PVX), potato virus M (PVM) and white clover mosaic virus (WCLMV) were purified and used as messengers in a wheat germ cell-free system. Each of these 3 viruses contained heavy genomic RNA species with MW .apprx. 2 .times. 106, which apparently were efficient templates for protein synthesis in vitro. This synthesis of high-MW polypeptides (180 .times. 103, 190 .times. 103 and 170 .times. 103) was directed by PVX, PVM and WCLMV RNA, respectively. None of the polypeptides directed by any of the RNA studied corresponded to the coat proteins.
