On the Tempo of Genome Size Evolution in Angiosperms
Figure 1
(a) Time-calibrated phylogeny of Monocotyledonae (monocots; [26]). Phylogeny is taken from a maximum likelihood analysis of 495 species based on combined analysis atpB, ITS, matK, ndhF, rbcL, rps16, and trnL-F. The major clades of monocots are labeled, and estimates of the likeliest growth form state (woody = brown; herbaceous = green) across all branches in the tree. Com+Zing represents the combined clade of Commelinales and Zingiberales. (b) The distributions of 1C DNA content among growth form, we detect no significant differences among herbaceous (green) and woody (brown) monocots for both 1C DNA and 1Cx DNA content (not shown). The boxplot represents the median (central line), 1st and 3rd quartiles (gray box), and outliers.
