The complete chloroplast genome sequence of a typical alpine fern Lepisorus waltonii (Ching) S. L. Yu in Polypodiaceae

Abstract

Lepisorus waltonii (Ching) S. L. Yu is a typical alpine fern species in the Qinghai-Tibet Plateau and Hengduan Mountain Regions. Here, we described the complete chloroplast genome of L. waltonii using Illumina paired-end sequencing. The chloroplast genome length is 157,148 bp, containing two inverted repeats (IR, 27,110 bp each) regions, separated by a large single-copy (LSC, 81,243 bp), and a small single-copy (SSC, 21,685 bp) regions, respectively. The genome contains 118 functional genes, including 85 protein-coding genes, 29 tRNA genes, and four rRNA genes. The total GC content of the chloroplast genome is 41.8%. ML phylogenetic analysis revealed that L. waltonii was closest related to Lepisorus clathratus.
