A Ca(2+)-sensitive system mediates low-affinity K(+) uptake in the absence of AKT1 in Arabidopsis plants.

Plant & cell physiology - 1 Dec 2012

Caballero Fernando, Botella María A, Rubio Lourdes, Fernández José A, Martínez Vicente, Rubio Francisco

Abstract excerpt

K(+) acquisition by Arabidopsis roots is mainly mediated by the high-affinity K(+) transporter AtHAK5 and the inward-rectifier K(+) channel AtAKT1. This model is probably universal to plants. Mutant plants lacking these two systems (athak5,atakt1) take up K(+) and grow when the external K(+) concentration is above a certain level, indicating that an additional transport system may compensate for the absence of...
