The Arabidopsis genome contains similar to70 genes for ion channels, of which 57 might be cation-selective channels (K+, Ca2+ or poorly discriminating channels). Here, we describe the different families of (putative) cation channels: the Shakers, the two-P-domain and Kir K+ channels (encoded by the KCO genes), the cyclic-nucleotide-gated channels, the glutamate receptors, and the Ca2+ channel TPC1. We also compare molecular data with the data obtained in planta, which should lead to abetter understanding of the identity of these channels and provide clues about their roles in plant nutrition and cell signalling.
