Complete chloroplast genome of the tree fern Alsophila podophylla (Cyatheaceae)

Abstract

The chloroplast genome of the tree fern Alsophila podophylla has been completely sequenced. The genome is 166,151 bp in size and features a typical quadripartite structure with the large (LSC, 86,762 bp) and small single copy (SSC, 21,641 bp) regions separated by a pair of inverted repeats (IRs, 28,874 bp each). It encodes 133 genes including 91 protein-coding genes, 33 tRNA genes, eight rRNA genes, and one pseudogene. Maximum-likelihood tree indicates that A. podophylla is sister to A. spinulosa. This work provides a solid molecular resource for surveying phylogeny and chloroplast genomics of ferns.
