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.
水分胁迫导致燕麦胚芽鞘细胞所产生蛋白质的类型发生质的变化,这可由双重标记比值技术加以证明,同时也使亮氨酸掺入蛋白质的速度出现数量上的减少。渗透剂甘露醇和 Carbowax-4000 使蛋白质合成的图形发生类似的变化,这表明这些效应是由于水分胁迫所致,而不是由于某种特殊的渗透剂的缘故。
