Abstract

Osmotic stress is known to induce a transient increase in cytoplasmic Ca2+ concentration [Ca2+]i in plants, and now OSCA1 is identified as a long-sought Ca2+ channel that mediates [Ca2+]i increases—mutants lacking OSCA1 function have impaired osmotic Ca2+ signalling in guard cells and root cells, and reduced transpiration regulation and root growth under osmotic stress.
