However,historically it was exactly this coordination of cell expansion that led to thediscovery of auxin.In their famous ThePower of Movement in Plants,the Darwinsdemonstrated for the phototropism of graminean seedlings that the direction oflight is perceived in the very tip of the coleoptile,whereas the growthresponse to this directional stimulus occurs at the coleoptile base (Drawin andDrawin 1880) .The signal transported from the tip to the base of the coleoptilemust transmit not only information about the fact that the coleoptile tip hasperceived light,but also information about the direction of the lightstimulus.
Simultaneously,but independently,Cholodny (1927),forgravitropism,and Went (1926),forphototropism,discovered that this transmitted signal must be a hormone.Bymeans of the famous Avena biotest thishormone was later found to be IAA (Kögl etal.1934; Thimann 1935) .TheCholodny−Went model explains tropistic curvature弯曲向性 by an alignment of auxin transportwith the stimulation vector.The resulting gradient of auxin between the twoflanks of the stimulated organ will then induce a growth differential thatdrives bending in the direction of the inductive stimulus.

然而,历史上,正是这种协调细胞膨胀,LED植物生长素的发现.在有名的力量在植物中的运动,对graminean幼苗光的方向在胚芽鞘顶端的向光性darwinsdemonstrated感知,而growthresponse这个方向的刺激发生在胚芽鞘基（图anddrawin 1880）.从冰山运到基地的coleoptilemust传输不仅对事实的胚芽鞘尖端hasperceived光信息的信号,而且对lightstimulus方向信息.同时,但独立,Cholodny-（1927）,forgravitropism,去（1926）,forphototropism,发现这个发送的信号必须是激素.著名的燕麦生物监测此激素通过后来被发现是IAA（KöGL等.1934；蒂曼1935）.thecholodny−去模型解释了向性的曲率弯曲向性生长素的对准将刺激向量.由此产生的梯度刺激器官之间的twoflanks生长素诱导的增长将微分动力在感性刺激的方向弯曲.
