Abstract
Changes in free and acetylated amino acids have been determined in control and infected tobacco plants during logarithmic tobacco mosaic virus multiplication. An increase in free amino acids occurs in infected tissue in the early stages of tobacco mosaic virus synthesis (72 and 144 h) followed by a decrease after 216 h. Acetylamino acids are not present in infected or in normal plant tissue in amounts that exceed 0.2 μmoles per 100 g of plant tissue. The induction of serine acetylase (acetyl-CoA: L-serine N-acetyltransferase) could not be demonstrated during logarithmic tobacco mosaic virus biosynthesis.
