Abstract

The complete chloroplast genome of Stephania tetrandra was sequenced and assembled for the first time. The chloroplast genome is 159,974 bp in length, containing a large single-copy (LSC) region of 90,539 bp and a small single-copy region (SSC) of 20,735 bp, separated by a pair of inverted repeats (IRs) of 24,350 bp. The genome contains 113 unique genes, including 79 protein-coding genes (PCGs), 30 tRNA genes, and four rRNA genes. Among them, 15 genes have one intron each and three genes contain two introns. The overall GC content is 37.8%, while the corresponding values of LSC, SSC, and IR regions are 35.8, 32.4, and 43.7%, respectively. Phylogenetic analysis showed that S. tetrandra is more closely related to the clade of two species within Stephania, providing new insight into the evolution of Menispermaceae.

Keywords: Complete chloroplast genome; Menispermaceae; Stephania tetrandra.
