Characterization of the complete chloroplast genome of Glycyrrhiza uralensis (Leguminosae), a traditional Chinese medicine

Abstract

Glycyrrhiza uralensis is a tradational Chinese medicine of Leguminosae, which contains many chemicals, such as glycyrrhizin, liquiritin glycyrol, melatonin (N-acetyl-5-methoxy tryptamine), glycyrrhizol A, glycyrrhizol B and four known isoflavonoids (5-O-methylglycryol, isoglycyrol, 6,8-diisoprenyl-5,7,4′-trihydroxy isoflavone, gancaonin). Illumina paired-end reads data was used to assemble the complete chloroplast (cp) genome. About 15,445,866 raw Paired-End Reads and the length distribution in 127,702 bp (GC content accounts for 34.3%). Eight PCG genes and six tRNA genes possess a single intron, while ycf3 has a couple of introns. Based on the concatenated coding sequences of cp PCGs, the phylogenetic analysis showed that Glycyrrhiza uralensis and Glycyrrhiza inflata (MH321931) are closely related to each other within the family Leguminosae.
