Abstract

Summary

The ability of the genome-linked protein (VPg) of cowpea mosaic virus (CPMV) to survive incubation in rabbit reticulocyte lysates was investigated. In contrast to the results obtained with picornavirus RNAs, there was no evidence for the specific removal (‘unlinking’) of the VPg from CPMV RNA during incubation. While linked to RNA, CPMV VPg was protected from proteolytic degradation; if the RNA was first digested with nuclease P1, rapid degradation of the VPg occurred. However if as few as 17 nucleotides were left attached to the VPg, stability was retained.
