Wounding of single leaflets of young tomato (Lycopersicum esculentum var. Bonnie Best) plants causes the release of a proteinase inhibitor inducing factor. This factor is rapidly transported throughout the plant where it causes accumulation of inhibitor I, a potent inhibitor of several serine proteinases from both animals and microorganisms. The wound-induced accumulation of inhibitor I is both light- and temperature-dependent. In total darkness no accumulation results from wounding. The accumulation exhibits a linear dependence upon light up to 300 foot candles. At 600 foot candles and above, the response is maximal. In light the wound response possesses an unusual temperature dependence with an optimum rate of accumulation near 36 C. Below 20 C no accumulation occurs. The over-all process contains two light- and temperature-dependent steps, one involving wounding and transport, the other involving accumulation.
叶片受伤会导致番茄(Lycopersicum esculentum var. Bonnie Best)植株释放蛋白酶抑制剂诱导因子。该因子迅速在植物体内运输,导致抑制剂 I 的积累,抑制剂 I 是几种来自动物和微生物的丝氨酸蛋白酶的强效抑制剂。抑制剂 I 的积累与光和温度有关。在完全黑暗中,受伤不会导致积累。在 300 英尺烛光的光线下,积累呈线性依赖关系。在 600 英尺烛光及以上,反应达到最大值。在光下,伤口反应具有不寻常的温度依赖性,最佳积累速率接近 36°C。低于 20°C 则不会发生积累。整个过程包含两个依赖光和温度的步骤,一个涉及受伤和运输,另一个涉及积累。
