The effect of indolylacetic acid (IAA) on proton conductivity of tylacoid membranes of isolated pea chloroplasts at pH 5.5-8.0 and of artificial phospholipid membranes at pH 7.5 were studied. IAA was shown to decrease the stationary proton gradient value and increase those of the dissociation constant and electron transport rate in chloroplasts, while in the artificial phospholipid membranes it increased the proton conductivity. The membrane lipid phase is supposed to be a possible result of phytohormone action, IAA transporting the protons according to the monomeric mechanism.
研究了吲哚乙酸（IAA）对分离的豌豆叶绿体类囊体膜在pH 5.5 - 8.0时以及人工磷脂膜在pH 7.5时质子传导率的影响。结果表明，IAA可降低叶绿体中稳态质子梯度值，增加解离常数和电子传递速率；而在人工磷脂膜中，IAA可提高质子传导率。膜脂相被认为是植物激素作用的一个可能结果，IAA根据单体机制转运质子。
