(two-armed) 4,13-diaza-18-crown-6 lariat ether and tris (macrocycle) hydraphile synthetic amphiphiles alter root morphology in Arabidopsis thaliana plants. The effect on root structure and growth depends both on the hydraphile spacer chain length and lariat ether side chain length as well as the concentration of compound in the growth medium. In some cases a correlation to ion transport activity was apparent
摘要Bibracchial(两臂)4,13-diaza-18-crown-6套索状醚和tris(大环)亲水性两亲物改变了拟南芥植物的根系形态。对根结构和生长的影响取决于亲水间隔基链长度和套索状醚侧链长度,以及生长培养基中化合物的浓度。在某些情况下,与离子迁移活性的相关性很明显,但是这种相关性并不总是很明显。出乎意料的是,平面双层电导(BLM)研究表明套索醚和套索醚酰胺均表现出良好的膜活性控制能力。大豆asolectin膜中的孔形成很容易发生,并且孔稳定且持续。低浓度的活性亲水物和套索状醚改变了初级:侧根的密度比,通常会增加它。转运蛋白介导的侧根密度的改变暗示了植物生长素的活性,例如吲哚-3-乙酸和2,4-二氯苯氧基乙酸,它们依赖于胞质钾离子浓度。通过使用抗生长素的拟南芥突变体,测试并消除了化合物干扰生长素途径的假说。离子载体不是直接充当生长素模拟物,而是会影响离子梯度,从而对根的发育产生类
