title: Nuclear membrane ion channels mediate root nodule development.
abstract: Previous work has implicated two predicted ion channels in mediating perinuclear calcium spiking, which is essential for rhizobia-induced root nodule formation in legumes. A new study demonstrates that these ion channels are preferentially permeable to cations, such as potassium, and are located in the nuclear envelope. Here, we consider ways in which the ion channels influence perinuclear calcium spiking and discuss a potentially broader role for nuclear membrane ion channels in signal transduction in plants.
