Abstract
Crepis rigescens, Diels 1921 is a traditional Chinese medicinal plant of Cichorioideae, which contains many chemicals, such as friedelin, β-sitosterol, stigmasterol, chlorogenic acid, and flavonoids, and so on, which has the characteristics of high medicinal value and small side effect. Crepis rigescens was used as folk medicines for anti-bacterial, and anti-oxidation, which also had a potential curative effect in preventing cardiovascular disease and anti-tumor. Illumina paired-end reads data were used to assemble the complete chloroplast (cp) genome. 14,425,796 raw paired-end reads and the length distribution in 124,685 bp, including a large single copy (LSC) region of 82,924 bp, a small single copy (SSC) region of 18,150 bp, and a pair of inverted repeat (IRs) regions of 25,128 bp. Besides, 10 protein-coding genes (PCGs) genes and 6 tRNAs genes possess a single intron, while clpP and ycf3 have a couple of introns. Based on the concatenated coding sequences of cp PCGs, the phylogenetic analysis showed that C. rigescens and Hypochaeris radicata (MH746729) are closely related to each other within the family Cichorioideae.
