Fig. 1: Genetic and phenotypic differentiation among A. thaliana biogeographical groups.
From: Ecological trade-offs drive phenotypic and genetic differentiation of Arabidopsis thaliana in Europe
The 71 genotypes (n = 11 for North relict, n = 13 for North cosmopolitan, n = 23 for Center cosmopolitan, n = 17 for South cosmopolitan, and n = 7 for South relict group) selected for experimentation in this study are depicted according to geographical and genetic clustering (A). Phenotypic differences in seed mass (B), fecundity under control, intraspecific competition and water stress conditions (C), and plant height (D) among biogeographical groups. Plot boxes (B–D) show the minimum, first quartile, median, third quartile, and maximum value. Reaction norms of fecundity in response to intraspecific competition (E) and water stress (F) among biogeographical groups. Data in E, F panels are presented as mean values +/− SEM. Different letters indicate significant differences in the mean trait between groups after Tukey’s HSD test.
