Characterization of the complete chloroplast genome of Alsophila gigantea (Cyatheaceae), an ornamental and CITES giant tree fern

摘要

We characterized the complete chloroplast genome of Alsophila gigantea (Cyatheaceae), an ornamental and CITES giant tree fern. Its genome size is 161,679 bp in length, containing a large single copy (LSC) of 92,315 bp and a small single copy (SSC) of 21,702 bp separated by a pair of inverted repeat regions (IRs) of 23,831 bp. The overall GC contents of the chloroplast genome are 41.4%. A total of 133 genes are?annotated, comprising 89 protein-coding genes, 33 tRNA, eight rRNA, and three pseudogenes. ML phylogenetic tree indicates that A. gigantea is sister to A. podophylla .
