Nuclear- and plastid-encoded rpl32 divergence among selected angiosperms. A. Maximum likelihood trees showing nonsynonymous (d N ) and synonymous (d S ) substitution rates for plastid-encoded rpl32 genes with three nuclear-encoded copies. Red branches indicate the nuclear-encoded rpl32 copies. Trees are drawn to the same scale shown in the bottom left. B. Correlation of synonymous and nonsynonymous substitution rates of rpl32. Significance of fit was evaluated by a Pearson correlation coefficient in the R package. The solid line represents the regression, which was analyzed using d N and d S on all branches except for the Thalictrum (open square), Aquilegia (open triangle), Populus (triangle) terminal branches, and the branch leading to Thalictrum and Aquilegia (square). The dashed line indicates d N /d S ratio is equal to one.
