Fig. 3From: New insights into polyploid evolution and dynamic nature of Ludwigia section Isnardia (Onagraceae)Evolutionary network of Ludwigia sect. Isnardia inferred from the subset of the ITS region. The arrow indicates the crown node of Isnardia. The A, M1M2, F1F2, and D clades are marked as in Fig. 1. Blue lines show the evolutionary signal from the A genome, red lines from the B genome, dashed red lines likely from the B genome, green lines from the D genome, brown lines from the M1 and M2 genomesBack to article page
