Abstract

SUMMARY

RNA extracted from particles of potato leafroll virus (PLRV) infected tobacco mesophyll protoplasts. Treating the RNA with proteinase K did not abolish its infectivity. In messenger-dependent rabbit reticulocyte lysate, PLRV RNA induced the synthesis of specific polypeptides: a major product of mol. wt. 71000 but no product the size of coat protein. PLRV RNA is therefore positive-stranded. A genome-linked protein (apparent mol. wt. 7000) was detected in preparations of PLRV RNA but no polyadenylate sequence was found. These features may prove to be characteristic of luteoviruses.
