Abstract

The mangrove fern Acrostichum aureum is widely distributed in the Indo West-Pacific and Atlantic East-Pacific regions. Here we assembled and annotated its chloroplast genome based on the Illumina sequencing reads. The complete chloroplast genome of A. aureum was 154,805 bp in length with the GC content of 38.38%. It contains a large single copy (LSC) region of 82,826 bp and a small single copy (SSC) region of 21,617 bp, separated by a pair of inverted repeat region (IRs) of 25,181 bp each. It contains 84 protein coding genes, 27 tRNA genes, and four rRNA genes. Phylogenetic analysis shows that A. aureum is closest to Ceratopteris cornuta in the subfamily Parkerioideae. The chloroplast genome of A. aureum reported here offers a useful resource for its phylogeography and conservation genetics studies.

摘要

红树林蕨Acrostichum aureum广泛分布在印度西太平洋和大西洋东太平洋地区。在这里，我们根据Illumina测序读数组装并注释了其叶绿体基因组。的完整的叶绿体基因组A.蕨是与38.38％的GC内容长度154 805人基点。它包含一个82,826 bp的大单拷贝（LSC）区域和一个21,617 bp的小单拷贝（SSC）区域，由一对分别为25,181 bp的反向重复区域（IR）隔开。它包含84个蛋白质编码基因，27个tRNA基因和4个rRNA基因。系统发育分析表明A.萝最接近水蕨枸骨亚科Parkerioideae。金黄色葡萄球菌的叶绿体基因组 本文报道的系统谱和保守遗传学研究提供了有用的资源。
