Experiments carried out with sealed plasma membrane vesicles show that the fusicoccin-binding site faces the cytoplasmic surface of the membrane. Stabilisation of the labile ATPase-14-3-3 complex in plasma membranes could be achieved by fusicoccin treatment in vivo or in vitro. The carboxylterminus probably represents the binding domain for 14-3-3 homologues.

By testing the fusicoccin binding activity of yeast membranes, the carboxy-terminal regulatory domain of AHA2 was found to be part of a functional fusicoccin receptor, a component of which was the 14-3-3 protein. ATP hydrolytic activity of AHA2 expressed in yeast internal membranes was activated by all tested isoforms of the 14-3-3 protein of yeast and Arabidopsis, but only in the presence of fusicoccin.

Roots of this mutant lacked inward-rectifying potassium channels and displayed reduced potassium (rubidium-86) uptake in the presence of ammonium.

A search performed to find high-affinity phosphate uptake mutants by using chlorate selections on plants containing Tag1 transposable elements yielded a chlorate-resistant mutant with a Tag1 insertion in CHL1. Analysis showed that chl1 mutants have reduced high-affinity uptake in addition to reduced low-affinity uptake.

J Biol Chem 1998, 273:12017-12023. A full-length cDNA for a membrane transporter was isolated from Brassica napus by its sequence homology to a previously cloned Arabidopsis low affinity nitrate transporter. The properties of the transporter are consistent with a proton cotransport mechanism for nitrate. Histidine is also transported with an affinity was in the millimolar range.
