Synthesis of Proteins in Tobacco Protoplasts Infected with Brome Mosaic Virus

Abstract

The proteins synthesized in protoplasts infected with strain V5 of brome mosaic virus have been studied. Four new proteins of mol.wt. 2, 3.5, 10 and 10.7 × 10⁴ were observed. These account for over 90% of the virus genome. The three proteins with lowest mol.wt. corresponded closely in size to those observed in protoplasts infected with cowpea chlorotic mottle virus.
