研究结果支持内源生长素类物质参与控制菜豆下胚轴弯钩伸直的观点。（cv.黑色情人节）。酸性吲哚被检测到在钩弥漫荧光; triiodobenzoic酸，生长素运输的抑制剂，防止红光诱导的不弯曲，和indoleacetic酸可以取代组织的手肘以上区域作为抑制剂的开放。吲哚乙酸也刺激小腿细胞的生长，红光增加了该组织对激素的敏感性。一个小的红光诱导的刺激生长素运输通过内半的下胚轴柄观察，可能与光诱导的弯曲的钩。
Evidence is presented to support the suggestion that endogenous auxinlike substances participate in controlling the unbending of the hypocotyl hook ofPhaseolus vulgarisL. (cv. Black Valentine). An acidic indole was detected in hook diffusates by fluorometry; triiodobenzoic acid, an inhibitor of auxin transport, prevented red light-induced unbending, and indoleacetic acid can be substituted for tissue just above the elbow region as an inhibitor of opening. Indoleacetic acid also stimulated growth of shank cells, and red light increased the sensitivity of this tissue to the hormone. A small red light-induced stimulation of auxin transport through the inside half of the hypocotyl shank was observed and may be related to light-induced unbending of the hook.
