Abstract

Ottelia cordata is a typical submerged plant to the family of hydrocharitaceae. In this work, complete chloroplast genome of O. cordata was assembled and characterized from high-throughput Illumina sequencing data. The chloroplasgenome of O. cordatais 157,869bp in length. The O. cordata cp genome encodes 128 functional genes, including 85 protein-coding genes, 35 tRNA genes, and 8 rRNA genes. The GC content of the genome was 36,57%. Its nucleotide composition is asymmetric with an overall A + T content of 63.44%. Phylogenetic analysis indicated that O. cordata is closely related to the Elodea. These results could offer molecular markers and helpful in understanding about the role of O. cordata evolution and protection.

摘要

Ottelia cordata是水生真菌科的典型淹没植物。在这项工作中，组装了O. cordata的完整叶绿体基因组，并从高通量Illumina测序数据进行了表征。O. cordata的叶绿体基因组的长度为157,869bp。所述O.鱼腥草CP基因组编码128的功能基因，包括85个蛋白质编码基因，35个tRNA基因，和8个rRNA基因。基因组的GC含量为36.57％。它的核苷酸组成是不对称的，总的A + T含量为63.44％。系统发育分析表明O.鱼腥草是密切相关的伊乐藻。这些结果可以提供分子标记，并有助于理解O. cordata的进化和保护。
