The polar, basipetal transport of indoleacetic acid helps to maintain polarity of auxin movement in coleoptiles of Avena sativa L. by opposing acropetal diffusion. This conclusion is supported by 3 different kinds of experiments. In all 3 experiments, sections took up (14)C carboxyl-labeled indole-3-acetic acid anaerobically, and the distribution of auxin within all sections was similar at the end of uptake.[LIST: see text].
吲哚乙酸的极性、向基运输通过对抗向顶扩散,有助于维持燕麦胚芽鞘中生长素运输的极性。这一结论得到了3种不同实验的支持。在所有3个实验中,切段在无氧条件下吸收了(14)C羧基标记的吲哚-3-乙酸,并且在吸收结束时所有切段内生长素的分布相似。[列表:见原文]
