Two spatially and temporally distinct Ca2+ signals convey Arabidopsis thaliana responses to K+ deficiency.


In plants, potassium (K+ ) homeostasis is tightly regulated and established against a concentration gradient to the environment. Despite the identification of Ca2+ -regulated kinases as modulators of K+ channels, the immediate signaling and adaptation mechanisms of plants to low-K+ conditions are only partially understood. To assess the occurrence and role… (More)
