The complete chloroplast genome of Foonchewia coriacea (Rubioideae: Rubiaceae): a monotypic species endemic to Guangdong, China

Abstract

Foonchewia coriacea, a monotypic genus of the Rubiaceae, is endemic to China. Its complete chloroplast genome was determined to be 153,114 bp in length and the GC content was 37.90%. The sequence includes a large single-copy region of 83,978 bp, a small single-copy region of 18,290 bp, and the inverted region is 25,423 bp in length. It contains 129 genes, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The maximum likelihood (ML) and Bayesian inference (BI) analyses revealed F. coriacea was closely related to Dunnia sinensis with strong bootstrap values, belonging to the subfamily Rubioideae.
