We present unresolved questions in plant abiotic stress biology as posed by 15 research
groups with expertise spanning eco-physiology to cell and molecular biology. Common …

To survive in the nutrient-poor habitats, carnivorous plants capture small organisms
comprising complex substances not suitable for immediate reuse. The traps of carnivorous …

OSCA/TMEM63s form mechanically activated (MA) ion channels in plants and animals,
respectively. OSCAs and related TMEM16s and transmembrane channel-like (TMC) …

Glutamate has dual roles in metabolism and signaling; thus, signaling functions must be
isolatable and distinct from metabolic fluctuations, as seen in low-glutamate domains at …

The ability to sense and respond to physical forces is critical for the proper function of cells,
tissues, and organisms across the evolutionary tree. Plants sense gravity, osmotic …

All plants are electrically excitable, but only few are known to fire a well‐defined, all‐or‐
nothing action potential (AP). The Venus flytrap Dionaea muscipula displays APs with an …

Plant glutamate receptor-like channels (GLRs) are transmembrane proteins that allow the
movement of several ions across membranes. In the model plant Arabidopsis, there are 20 …

Plants show long-range cytosolic Ca 2+ signal transduction in response to wounding.
Recent advances in in vivo imaging techniques have helped visualize spatiotemporal …

Subgenome dominance after whole-genome duplication generates distinction in gene
number and expression at the level of chromosome sets, but it remains unclear how this …

This Viewpoint, which accompanies a Special Issue focusing on membrane
mechanosensors, discusses unifying and unique features of both established and emerging …
