A rhythm was found in protein synthesis accompanying rhythmic leaflet opening and closing in the dark in the plant Albizzia. More protein was synthesized during the opening of the leaflets than during the closing. Furthermore, an inhibitor of protein synthesis, cycloheximide, prevented rhythmic opening of leaflets but had no effect on rhythmic closing. It is suggested that protein synthesis is involved in the movement across membranes of K(+) ions that cause turgor changes and leaflet movement.
在植物合欢中发现,在黑暗条件下,伴随着小叶有节奏的开合,蛋白质合成也存在一种节律。小叶张开时合成的蛋白质比闭合时更多。此外,蛋白质合成抑制剂环己酰亚胺可阻止小叶有节奏地张开,但对有节奏的闭合没有影响。这表明蛋白质合成参与了钾离子跨膜运动,而钾离子跨膜运动导致了膨压变化和小叶运动。
