Fig. 1From: The chloroplast genome evolution of Venus slipper (Paphiopedilum): IR expansion, SSC contraction, and highly rearranged SSC regionsThe length of plastid genome size, LSC, SSC, and IR regions were plotted on the ML tree of Paphiopedilum. LSC, SSC, and IR regions were scaled differently. The six samples in bold only have trnL-UAG preserved in the SSC regionBack to article page
