The effect of ethylene (10 p.p.m.) on the rate of incorporation of [1-(14)C]glycerol into phospholipids of etiolated pea stems was studied. After 2-3h treatment with ethylene, incorporation was decreased by 50%. It remained at this value for as long as ethylene was supplied (8h). Handling the plants also caused a temporary decrease in incorporation, which we attribute to the production of endogenous ;wound' ethylene. The percentage decrease in incorporation was the same in four major phospholipid fractions, i.e. phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylinositol.
研究了乙烯(10 ppm)对[1-(14)C]甘油掺入黄化豌豆茎磷脂速率的影响。用乙烯处理2-3小时后,掺入量降低了50%。只要供应乙烯(8小时),掺入量就保持在这个水平。处理植株也会导致掺入量暂时下降,我们将其归因于内源性“创伤”乙烯的产生。在四种主要磷脂组分,即磷脂酰胆碱、磷脂酰乙醇胺、磷脂酰甘油和磷脂酰肌醇中,掺入量的降低百分比是相同的。
