Complete chloroplast genome and phylogenetic analysis of Smallanthus sonchifolius (Asteraceae)

Figures & data

Figure 1. Species reference images of S. sonchifolius (species images from Yin Juan, taken in a field in Qujing, Yunnan Province, 2022). (a) the leaves and flowers of S. sonchifolius; (b) and (c) the tubers of S. sonchifolius.

Figure 2. The chloroplast genome map of S. sonchifolius. Genes on the inside of the circle are transcribed in a clockwise direction and genes on the outside of the circle are transcribed in a counter-clockwise direction. The light gray and dark gray shadows inside the inner circle indicated at and GC content, respectively.
