Figure 1.
Portion of 35 trnH-psbA sequences including 25–27bp inversion and 18bp flanking inverted repeats.
Groups of conspecific sequences are shaded. Asterisks mark sequences with the A inversion configuration. Plus signs at the top of the alignment mark invariant sites. Inversion region is in box.
Figure 2.
Neighbor-joining trees resulting from two treatments of trnH-psbA inversion.
(A) NJ tree resulting from analysis of unedited raw sequence matrix, in which different taxa have either one or the other of two inversion configurations, and (B) NJ tree resulting from analysis of unedited uniform inversion matrix, in which the loop region of sequences with the A configuration has been replaced with its reverse complement. Conspecific sequences are indicated in colored boxes. Gs. = Gentianopsis, F. = Frasera, S. = Swertia, L. = Lomatogonium, C. = Comastoma, Gl. = Gentianella, G. = Gentiana. Two subtribes of Gentianaceae and two sections of Gentiana are indicated in gray boxes. Sequences with the A configuration are noted with an asterisk. Bootstrap values >50% are given above branches. The scale bar refers to both trees.
