TY - T1 - Rapid depolarization and cytosolic calcium increase go hand-in-hand in mesophyll cells’ ozone response SN - / UR - http://hdl.handle.net/10138/335823 T3 - A1 - Nuhkat, Maris; Brosché, Mikael; Stoelzle-Feix, Sonja; Dietrich, Petra; Hedrich, Rainer; Roelfsema, M.Rob G.; Kollist, Hannes A2 - PB - Y1 - 2021 LA - eng AB - Plant stress signalling involves bursts of reactive oxygen species (ROS), which can be mimicked by the application of acute pulses of ozone. Such ozone-pulses inhibit photosynthesis and trigger stomatal closure in a few minutes, but the signalling that underlies these responses remains largely unknown. We measured changes in Arabidopsis thaliana gas exchange after treatment with acute pulses of ozone and set up a system for simultaneous measurement of membrane potential and cytosolic calcium wit...
