Water stress and protein synthesis: I. Differential inhibition of protein synthesis.

Water stress causes both a qualitative change in the types of proteins produced by Avena coleoptile cells as demonstrated by a double-labeling ratio technique, and a quantitative reduction in the rate of incorporation of leucine into proteins. The osmotica mannitol and Carbowax-4000 cause similar changes in the pattern of protein synthesis showing that these effects are due to water stress rather than to a particular osmoticum.
