Phototropism is one of the common growth responses of plants to unilateral irradiation. Went proposed that phototropism is caused by a lateral gradient of growth-promoting auxin in the bending organ (Cholodny-Went theory). Recently, Bruinsma found that the shaded half did not contain more auxin than the illuminated ones as required by the C.-W. theory. Instead it was found that the even distribution of auxin was accompanied by a lateral gradient of growth-inhibitory substances during phototropic curvature.We have been investigating the relationship between plant growth inhibitors and growth inhibition by light in plants, and have succeeded in isolation some light-induced growth inhibitors and these precursors related to phototropism, raphanusanins from radish (Raphanus sativus var. hortensis f. gigantissimus M.) hypocotyls, 6-methoxy-2-benzoxazolinone from light-grown maize (Zea mays L.) shoots, 3-hydroxy-β-ionone from light-grown dwarf bean (Phaseolus vulgaris) shoots, p-hydroxy cinnamic acid from light-grown bean (Vigno mango L.) seedlings, unsaturated fatty acid hydroperoxides from light-grown buckwheat (Fagopyrum esculentum) seedlings and 8-epixanthatin from sunflower (Helianthus annuus L).

向光性是植物对单侧辐射的一种常见的生长反应。温特提出向光性是由弯曲器官中生长促进生长素的横向梯度引起的（乔罗德尼-温特理论）。最近，Bruinsma发现，阴影的一半并没有像C. W.理论本研究从萝卜（Raphanus sativus var.霍滕西斯湾（Atomitissimus M.）下胚轴，6-甲氧基-2-苯并恶唑啉酮从光生长玉米（玉米L.）嫩茎中的3-羟基-β-紫罗酮、嫩茎中的对羟基肉桂酸、嫩茎中的3-羟基-β-紫罗酮、嫩茎中的对羟基肉桂酸、嫩茎中的对羟基幼苗、来自光生荞麦（Fagopyrum esculentum）幼苗的不饱和脂肪酸氢过氧化物和来自向日葵（Helianthus annuus L）的8-表黄嘌呤。
