We have shown the presence of abscisic acid (ABA) in abaxial epidermal strips taken from Tulipa gesneriana and Commelina communis and that the ABA level rises in the epidermis when leaves are water stressed. ABA levels had risen 50% in the abaxial epidermis of C. communis 30 min after the leaves lost 10% of their fresh weight. Epidermis from both T. gesneriana and C. communis metabolize [(14)C]ABA to several products probably including phaseic acid (PA) and dihydrophaseic acid (DPA).
我们已经证明，在从郁金香和鸭跖草中取出的远轴表皮条带中存在脱落酸（ABA），并且当叶片受到水分胁迫时，表皮中的 ABA 水平会升高。在叶片失去 10%的鲜重后 30 分钟，鸭跖草远轴表皮中的 ABA 水平上升了 50%。来自郁金香和鸭跖草的表皮将 [(14)C]ABA 代谢为几种产物，可能包括黄烷酸（PA）和二氢黄烷酸（DPA）。
