On the Tempo of Genome Size Evolution in Angiosperms
Figure 2
(a) Time-calibrated phylogeny of Fabaceae (legumes). Phylogeny is taken form a maximum likelihood analysis of 253 species based on a combined analysis of ETS, ITS, matK, psbA-trnH, rbcL, and trnL-F. The major clades of legumes are labeled and estimates of the likeliest growth form state (woody = brown; herbaceous = green) across all branches in the tree. (b) The distributions of 1C DNA content among growth form, where we find significant differences among herbaceous (green) and woody (brown) legumes for both 1C DNA and 1Cx DNA content (not shown), but no more different than could arise by chance (see Methods and Materials). The boxplot represents the median (central line), 1st and 3rd quartiles (gray box), and outliers.
