Calcium influx into corn roots as a result of cold shock.
Corn roots or washed corn root tissue exposed to cold shock absorb 20 to 24% more (45)Ca(2+) into a nonexchangeable phase than control roots. Addition to fusicoccin largely prevents this additional calcium influx. The results are discussed in relation to injury-induced changes in membrane permeability of root cell membranes.
