Figure 1From: Natural variation in CBF gene sequence, gene expression and freezing tolerance in the Versailles core collection of Arabidopsis thalianaPhenotyping the core collection following acclimation and a freezing period of -5°C for 48 hours. A. Scale of notation from 0 (no damage) to 6 (dead plants). B. Example of a flat containing accessions with contrasting phenotypes. Each accession was noted at least 3 times and a mean score was calculated. Plants were photographed after 5 days of recovery.Back to article page
