Analysis of response strength in Arabidopsis plant traits. Response strength is defined as the absolute (i.e. positive or negative) variation from the Col-0 wild-type trait values. Response strength was analyzed for reproductive fitness (a), flowering time (b), relative water content (c), and osmotic potential (d). Trait values of the Col-0 genotype were subtracted from the corresponding values for all other genotypes, transformed to positive values, and plotted, with genotypes from left to right arranged from the shortest (tert) to the longest (ku70) telomere length. Points show least-squared means ± SE.
