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. ARTICLE HISTORY

Integrated analysis of three newly sequenced fern chloroplast genomes: Genome structure and comparative analysis

“…Genes are interrupted by introns in the major groups of organisms. One-intron genes vary among species, whereas clpP, rps12, and ycf3 have been found to be two-intron genes (Brouard et al, 2016;S. Liu et al, 2017;Ting Wang et al,.., 2018); these findings were consistent with our observations, except for P. tripteron.…”

Integrated analysis of four new sequenced fern Chloroplast Genomes: Genome structure and Comparative Analysis

“…Four fern genomes encoded 132-135 genes, composed with 89 protein-coding, eight ribosomal RNAs and 35-38 transfer RNA genes in this study. The genes clpP, ycf3, and rps12 were found containing two introns, was also reported in many other ferns, as Alsophila podophylla [30] and Alsophia gigantea [31]. matK only in P. tripteron was found had two introns in this study.…”

Phylogenetic significance of the characteristics of simple sequence repeats at the genus level based on the complete chloroplast genome sequences of Cyatheaceae

“…The leaves of Gymnospaera podophylla Hook and Gymnospaera gigantea Wall. ex Hook were collected from the South China Botanical Garden of the Chinese Academy of Sciences in Guangzhou (Liu et al., 2018 ; Wang et al., 2019b ). The leaves of Alsophila costularis Baker, Sphaeropteris brunoniana (Hook.)…”
