Characterization of the complete chloroplast genome of Barbella flagellifera (Cardot) Nog. 1938 (Bryidae, Meteoriaceae)

Abstract

AbstractWhether Barbella flagellifera (Cardot) Nog. belongs to Neodicladiella has not yet been determined, and a study of the complete chloroplast (cp) genome of B. flagellifera would aid in determining its evolutionary position. In this study, we aimed to sequence the complete cp genome of B. flagellifera, an epiphytic species found in tropical and subtropical forests. The complete cp genome is 125,025 base pairs (bp) long and appears as a typical quadrilateral structure with a large single-copy (86,854 bp), a small single-copy (18,473 bp), and a pair of inverted repeats (19,698 bp). The overall GC content of the sequence is 41.0% and the genome encodes 127 genes, including 82 protein-coding genes, 37 tRNAs, and eight rRNAs. Phylogenetic analysis reveals that B. flagellifera clustered into a clade with other Hypnales groups with high bootstrap support. The complete cp genome presented here will provide helpful information for species identification of Barbella genus and Neodicladiella genus in Meteoriaceae.
