Trait quantification and their correlation in 387 Arabidopsis accessions. A, Phenotype of representative Arabidopsis accessions before submergence (control), after 13 days of submergence, and 1-day post desubmergence. The numbers indicate the visual score indicating the proportion of vigorous green leaves to total number of leaves (score 10 = all leaves vigorous, score 5 = 50% of leaves stress affected). B, Distributions of the seven quantified traits in 387 Arabidopsis accessions under the three experimental conditions (control; submergence, sub; desubmergence, desub). Asterisks indicate a statistically significant difference for a comparison of treatments against control (ANOVA, Tukey’s HSD test, P <0.01). The box plots indicate the first and third quartiles with a median line and the whiskers represent the 1.5× interquartile range. C, Pearson correlation of all determined traits under control (black text), submergence (orange text), and desubmergence (green text) conditions. For significant correlations (P <0.01) the color scale indicates the correlation coefficient (R).
