Fig. 1From: Between-species differences in gene copy number are enriched among functions critical for adaptive evolution in Arabidopsis halleri Comparison of the metal hyperaccumulator species Arabidopsis halleri to the closely related non-hyperaccumulator species A. lyrata and A. thaliana. A representative photograph is shown for each species, together with the estimated evolutionary distances separating them, given as the divergence times from a common ancestor [96]. Listed below are key phenotypic and genomic characteristics. Mya, million years agoBack to article page
