Abstract

The fundamental question in cold acclimation is how do plants perceive thelow but nonfreezing temperatures that activate cold acclimation responses. New findings in the past year suggest that changes in membrane fluidity, cytoskeleton rearrangement, and calcium influxes are among the earliest events taking place in plants upon exposure to low nonfreezing temperatures. Inthe cyanobacterium Synechocystis PCC6803, temperature change is detected by at least two separate sensors. One of these measures membrane fluidity using a classical two-component system involving histidine kinases and a response regulator in a His-to-Asp phosphorelay. Although these Synechocystis results may not be directly relevant to cold acclimation, they can guide ourthinking as we search for biological thermometers in higher plants.
