The light-induced increase in the activity of hydroxycinnamoyl-CoA: quinate hydroxycinnamoyl transferase (CQT) in hypocotyls of etiolated buckwheat seedlings is not suppressed by aminooxy acetic acid, an inhibitor of cinnamic acid formation in this tissue. Incubation of hypocotyls in 2 mmol l(-1) trans-cinnamate in the dark does not increase CQT activity. Thus, trans-cinnamate does not appear to mediate the effect of light on CQT in buckwheat hypocotyls.
光诱导的荞麦下胚轴中对羟基肉桂酰辅酶 A：奎尼酸对羟基肉桂酰转移酶（CQT）活性的增加不受氨氧乙酸的抑制，氨氧乙酸是该组织中肉桂酸形成的抑制剂。在黑暗中用 2 mmol l（-1）反式肉桂酸孵育下胚轴不会增加 CQT 活性。因此，反式肉桂酸似乎不会介导光对荞麦下胚轴中 CQT 的影响。
