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. [ABSTRACT FROM AUTHOR]

Leptochilus decurrens is a small tropical fern of Polypodiaceae, but also a least concern folk medicinal fern. Its genome size is 153,753 bp with a pair of 21,664 bp inverted repeat regions (IR), a large single-copy (LSC) region of 84,395 bp and a small single-copy (SSC) region of 26,030 bp. A total of 133 genes were predicted, including 88 protein-coding genes, 37 tRNA genes and eight rRNA genes. The ML analysis reveals that L. decurrens is sister to Leptochilus hemionitideus forming monophyletic group closely related with polypodiaceous ferns. The work provides vigorous molecular data to further promote phylogenetics of Polypodiaceae. [ABSTRACT FROM AUTHOR]

Polypodiodes amoena is an important medical fern of Polypodiaceae. Its complete chloroplast genome is obtained through Illumina sequencing, which is 152,067 bp in length with a large single copy (LSC) region (81,187 bp), a small single copy (SSC) region (21,590 bp), and two inverted repeats (IRa and IRb) regions (24,645 bp). The genome encodes 130 genes, including 88 protein-coding genes, 33 tRNA genes, eight rRNA genes, and one pseudogene. ML phylogenetic analysis reveals that P. amoena is clustered with polypodiaceous ferns. [ABSTRACT FROM AUTHOR]

We reported the complete chloroplast genome of Pyrrosia calvata, a traditional Chinese medicinal fern only restricted to Guangxi, China. Its genome is 158,201 bp in length with 41.59% GC content and includes two inverted repeats (IRs) of 26,983 bp separated by LSC and SSC of 82,517 bp and 21,718 bp, respectively. A total of 131 genes are predicted, including 88 protein-coding genes, 34 tRNA genes, eight rRNA genes, and one pseudogene. ML tree indicates that P. calvata is sister to Lepisorus clathratu. This study provides a new perspective to explore the phylogenetic relationship of Pyrrosia. [ABSTRACT FROM AUTHOR]

Macrothelypteris torresiana is a reputed medicinal fern. Its complete chloroplast genome was determined by Illumina paired-end sequencing. The genome is 151,150 bp in length with 43.1% overall Guanine+Cytosine (GC) content, which is divided into four distinct parts such as a small single copy (SSC, 21,772 bp), a large single copy (LSC, 82,422 bp), and two inverted repeats (IRs, 23,478 bp each). It contains 132 genes, including 86 protein-coding genes, eight ribosomal RNA genes, 35 tRNA genes, and three pseudogenes. Maximum likelihood (ML) tree revealed that M. torresiana was closely grouped with Christella appendiculata with 100% bootstrap value. [ABSTRACT FROM AUTHOR]
