Abstract excerpt
Ca2+ is absorbed by roots and transported upward through the xylem to the apoplastic space of the leaf, after which it is deposited into the leaf cell. In Arabidopsis (Arabidopsis thaliana), the tonoplast-localized Ca2+/H+ transporters CATION EXCHANGER1 (CAX1) and CAX3 sequester Ca2+ from the cytosol into the vacuole, but it is not known what transporter mediates the initial Ca2+ influx from the apoplast to the...
