Complex Formation between Indole-3-acetic Acid and Phospholipid Membrane Components in Aqueous Media. 3. Interaction of Indole-3-acetic Acid with Amphiphiles Containing the Trimethylammonium Group? Graham P. Jones and Leslie G. Paleg*
ABSTRACT: Specific structural aspects of the interaction between the plant hormone indole-3-acetic acid (IAA) and phosphatidylcholine (PC) have been investigated by nuclear magnetic resonance (NMR) techniques. IAA-induced ‘H changes in chemical shift of compounds containing a trimethylammonium group have been monitored. Small IAAinduced changes are observed (
