2004 m. Nr. 1 The role of transmembrane potential of plant cell plasmalemma in vitro in the functional activity of IAA–receptor complexes
In model experiments on plasmalemma vesicles isolated from etiolated wheat (Triticum aestivum L.) coleoptiles, it has been shown that formation of the K+-diffusive potential enhances the functional activity of IAA–protein complexes, evaluated with respect to RNA-polymerase II activity. This change does not follow from the increased IAA-binding capacity of the plasmalemma and seems to reflect an intensified functional activity of the hormone-receptor system.
