The chloroplast genome of Adiantum reniforme var. sinense, an endangered fern endemic to China

Adiantum reniforme var. sinense, a rare and endangered fern endemic to Chongqing, China, has been listed as one of the National Key Protected Wild Plants (Class I) in China. Here we assembled its chloroplast genome (cp genome) using Illumina sequencing reads to offer a genetic resource for future conservation genetic studies. The complete cp genome of A. reniforme var. sinense was 150,109 bp in length with an overall GC content of 42.85%. It contains a large single copy (LSC) region of 83,274 bp and a small single copy (SSC) region of 21,459 bp, separated by a pair of inverted repeat regions (IRs) of 22,688 bp each. The cp genome contains 84 protein coding genes, 28 tRNA genes, four rRNA genes, and one pseudogene (ψrps16). Phylogenetic analysis showed that A. reniforme var. sinense clustered together with four other Adiantum species and was sister to A. capillus-veneris.
