Autoactive CNGC15 enhances root endosymbiosis in legume and wheat.

ABSTRACT: Nutrient acquisition is crucial for sustaining life. Plants develop beneficial intracellular partnerships with arbuscular mycorrhiza (AM) and nitrogen-fixing bacteria to surmount the scarcity of soil nutrients and tap into atmospheric dinitrogen, respectively^1,2. Initiation of these root endosymbioses requires symbiont-induced oscillations in nuclear calcium (Ca²⁺) concentrations in root cells³. How the nuclear-localized ion channels, cyclic nucleotide-gated channel (CNGC) 15 and DOESN'T MAKE INFECTIONS1 (DMI1)⁴ are coordinated to specify symbiotic-induced nuclear Ca²⁺ oscillations remains unknown. Here we discovered an autoactive CNGC15 mutant that generates spontaneous low-frequency Ca²⁺ oscillations. While CNGC15 produces
