The vacuolar H+/Ca transporter CAX1 participates in submergence and anoxia stress responses (Plant Physiol)

Calcium (Ca) signaling is one of the primary plant responses to confront abiotic stresses. To coordinate Ca levels in the different compartments of the cell, several transporters are needed including the H+/Ca exchangers (CAXs) in the tonoplast (vacuolar membrane). While the role of calcium signaling…

Ethylene augments root hypoxia tolerance through amelioration of reactive oxygen species and growth cessation (bioRxiv)

Flooding presents a dual threat to plants; not only is mitochondrial respiration supressed during the resulting hypoxic conditions, but once the floodwaters recede, the return to ambient oxygen levels triggers a cascade of harmful reaction oxygen species (ROS). One of the most well-studied responses…
