Abstract

Abstract: Ligularia biceps is a plant belonging to Ligularia Cass., most of which have certain medicinal value. In this study, the chloroplast (cp) genome of L. biceps was sequenced for the first time. The L. biceps cp genome sequence length was 151, 153 bp, with an large single-copy (LSC) region length of 83, 259 bp, an small single-copy (SSC) region length of 18, 234 bp, a pair of inverted repeat regions (IRs) length of 24, 830 bp and GC content of 37.5%. In total, 131 genes were annotated, including 86 protein-coding genes, eight rRNA genes, and 37 tRNA genes. The phylogenetic tree was built based on 23 species, using the maximum-likelihood method. The results showed that the species clustered with other Ligularia Cass. species. This study provides a theoretical basis for establishing a classification system.
