Characterization of the complete chloroplast genome of Sansevieria trifasciata var. Laurentii

摘要

Sansevieria trifasciata var. laurentii (S. trifasciata) is a kind of popular in-door and out-door plant around world, it is not only known as the ornamental plant, but also as medical plant. It belongs to the Draceanaceae family, Draceanaceae includes more than 60?species distributed in tropical and subtropical dry climate regions. In this study, we sequenced the sample of S. trifasciata and determined its complete chloroplast genome. The length of CP genome is 155,179?bp, includes two invert repeats (IR) regions of 26,513?bp, a large single copy (LSC) region of 83,680?bp and a short single copy (SSC) region of 18,473?bp. There are 133 genes, which includes 87 protein coding genes, 8 rRNA and 38 tRNA, and 37.5% overall GC content. Each of trn K-UUU, rps 16, trn G-UCC, atp F, rpo C1, trn L-UAA, trn V-UAC, pet B, pet D, rpl 16, rpl 2, ndh B, trnI -GAU, trn A-UGC and ndh A genes contains a intron, clp P and ycf 3 contains 2 intron. The phylogenetic position shows that S. trifasciata has the closest relationship with Rohdea Chinensis (MH356725.1).
