The complete chloroplast genome of Vandenboschia striata, a common and widespread filmy fern (Hymenophyllaceae).

Vandenboschia striata is a common and widespread filmy fern of Hymenophyllaceae. Its complete chloroplast genome is 147,014 bp in length, including a large single copy (LSC) region of 89,886 bp, a small single copy (SSC) region of 20,850 bp, and a pair of inverted repeats (IRs) of 18,139 bp. Totally, 132 genes are predicted in the cp genome embodies, including 88 protein coding genes, 36 tRNA genes, and eight rRNA genes. A maximum-likelihood tree was constructed to explore phylogenetic relationship. The result showed that V. striata was sister to V.speciosa with 100% bootstrap support. The complete chloroplast genome sequences of V. striata would be beneficial to further phylogenetic survey on classification of the related species or genera in Hymenophyllaceae.

The complete chloroplast genome of Alsophila latebrosa, a common and widespread tree fern (Cyatheaceae).

Alsophila latebrosa is a common and widespread tree fern of Cyatheaceae. Its complete chloroplast genome is first assembled and reported with 155,724 bp in length, including a large single copy (LSC) region of 85,800 bp, a small single copy (SSC) region of 21,620 bp, and a pair of inverted repeats (IRs) of 24,152 bp. The genome has 133 genes, including 89 protein-coding genes, 33 tRNA genes, eight rRNA genes and three pseudogenes. Maximum likelihood approach was employed to construct the phylogenetic relationship among ten ferns including A. latebrosa. The result showed that A. latebrosa was most related to A. costularis as a sister group with 100% bootstrap support. The complete chloroplast genome sequences of A. latebrosa will provide valuable genomic information to further illuminate phylogenetic classification of Cyatheacea.

The complete chloroplast genome sequence of Crepidomanes latealatum (Bosch) Copel.

The complete chloroplast genome sequence of Crepidomanes latealatum (Bosch) Copel. was determined in the present study. The genome is 145,943 base pairs (bp) in length and comprised two inverted repeats (32,990 bp) between a large single copy (92,170 bp) and a small single copy (20,783 bp). It contains 88 coding genes, 8 rRNA genes, 34 tRNA genes, and 1 pseudogene of trnL-UAA, and the GC content is 37.6%. Molecular phylogenetic analysis based on the plastid genome sequences of related taxa strongly supported the monophyly of the family Hymenophyllaceae, and the genus Vandenboschia was a sister group of Crepidomanes. In addition, compared to C. minutum, two large deletions of 453 bp and 878 bp were found in the IGS regions of petA-psbI and rrn16-trnV-GAC of C. latealatum cp genome, respectively.

The complete chloroplast genome sequence of Cyrtomium fortunei (Dryopteridaceae), an important medical fern.

The complete chloroplast genome of an important medical fern Cyrtomium fortunei has been sequenced. Its genome is 151,699 bp in length with a pair of inverted repeats (IRs, 23,875 bp), separated by a small single copy region (SSC, 21,625 bp) and a large single copy region (LSC, 82,324 bp). It contains 132 genes, covering 88 protein coding genes, 35 tRNA genes, eight rRNA genes, and one pseudogene. Maximum likelihood analysis indicates that the phylogenetic tree is monophyletic with three clades. Cyrtomium fortunei is closely related to C. devexiscapulae, which further forms a sister clade to C. falcatum.

The complete chloroplast genome of Eastern Asian fern Bolbitis laxireticulata (Dryopteridaceae).

Bolbitis laxireticulata is a potential ornamental plant, which is restricted to eastern Asia. Here, we sequenced the complete chloroplast (cp) genome of B. laxireticulata and constructed a phylogenetic cp tree of Dryopteridaceae to study their relationships. The cp genome of B. laxireticulata is 153,093 bp in length, being made up of large single-copy (LSC, 83,169 bp), small single-copy (SSC, 21,538 bp), and a pair of region inverted repeats (IRs, 24,193 bp). It has 124 genes including 83 protein-coding genes, 33 tRNA genes, and eight rRNA genes. With the maximum-likelihood tree indicating, B. laxireticulata is more closely related to B. subcordata.
