A family of plant nuclear ion channels, including DMI1 (Does not Make Infections 1) and its homologs CASTOR and POLLUX, are required for the establishment of legume-microbe symbioses by generating nuclear and perinuclear Ca<sup>2+</sup> spiking. Here we show that CASTOR from Lotus japonicus is a highly selective Ca<sup>2+</sup> channel whose activation requires cytosolic/nucleosolic Ca<sup>2+</sup>, contrary to the previous suggestion of it being a K<sup>+</sup> channel. Structurally, the cytoso ...[more]
