Complete chloroplast genome of Lycoris sprengeri (Amaryllidaceae) and genetic comparison

Lycoris sprengeri is native to China and has various variations. It belongs to the Amaryllidaceae family, which contains abundant alkaloids for medical use and also was planted as garden bulbous flowers. In this study, we assembled the complete chloroplast (cp) genome of L. sprengeri by DNA sequencing, which will improve the complete cp genomic information for analysis of phylogenetic relationships and germplasm identification in Lycoris. The whole cp genome is 158,687 bp, which contained a large single-copy region (LSC) of 86,489 bp, a small single-copy region (SSC) of 18,540 bp, and a pair of inverted repeats (IRs) of 26,829 bp. A total of 137 genes were annotated, including 87 protein coding genes (PCGs), 42 tRNA, and 8 rRNA genes. Phylogenetic tree analysis revealed that the close relationship of three species of Lycoris (L. sprengeri, L. radiate, and L. squamigera) in the Amaryllidaceae family.
