Complete plastid genome sequence of the rare and endangered medicinal herb Psammosilene tunicoides, endemic to China.

ABSTRACT: Psammosilene tunicoides W.C. Wu et C.Y. Wu, a monotypic species and endemic to Southwest China, is a rare and endangered traditional medicinal herb with satisfactory effects on multifold pathology. In order to provide crucial data for protection, we reported and analyzed the complete plastid genome of P. tunicoides as the foundation of germplasm conservation. The complete plastid genome is a typical quadripartite circular molecule of 153,957 bp in length, including a large single copy (LSC) region of 83,972 bp and a small single copy (SSC) region of 17,495 bp separated by two inverted repeat (IR) regions of 26,245 bp. In total of 111 unique genes were predicted, including 78 protein-coding genes (PCGs), 29 transfer RNA genes, and four ribosomal RNA genes. The overall GC content of P. tunicoides is 36.5%. The phylogenetic analysis revealed that P. tunicoides and Dianthus caryophyllus formed an independent clade with a 100% bootstrap support.
