Abstract

The complete chloroplast genome of an important medicinal plant, Veratrum nigrum Linnaeus, was sequenced. The entire circular genome is 151,580 bp in length, with 37.7% GC contents. The genome has a large single-copy (LSC) region with a length of 81,806 bp, a small single-copy (SSC) region with a length of 17,472 bp, and two inverted repeat regions (IRs) with a length of 26,151 bp. It harbored 131 genes, including 85 protein coding genes, 38 tRNA genes, and eight rRNA genes. Phylogenetic analysis suggested V. nigrum formed a monophyletic clade with relatively short genetic distance to Veratrum oxysepalum and Veratrum taliense. This study will provide theoretical basis for further study on plant genetics phylogenetic research.
