Plant "helper" immune receptors are Ca²⁺-permeable nonselective cation channels.

Plant nucleotide-binding leucine-rich repeat receptors (NLRs) regulate immunity and cell death. In <i>Arabidopsis</i>, a subfamily of "helper" NLRs is required by many "sensor" NLRs. Active NRG1.1 oligomerized, was enriched in plasma membrane puncta, and conferred cytoplasmic calcium ion (Ca<sup>2+<... View More
