Interaction with Diurnal and Circadian Regulation Results in Dynamic Metabolic and Transcriptional Changes during Cold Acclimation in Arabidopsis
Figure 10
Freezing tolerance of circadian mutants cca1-11, lhy-21 and cca1-11/lhy-21 compared to the wild-type Ws.
A, Electrolyte leakage was measured in whole seedlings frozen at different temperatures, either before (NA) or after cold acclimation (ACC). A total of four replicates were measured. B, The survival of the circadian mutants after exposure to freezing temperatures was estimated as the percentage of NA and ACC seedlings surviving the different temperatures after 7 d of recovery under control conditions.
