Abstract

Saccharina latissima is a brown algal (class Phaeophyceae) belonging to the family Laminariaceae. We reported the de novo assembly and the annotation of the complete chloroplast genome of S. latissima. The circled cpDNA of S. latissima is 130,619 bp in length with a large and a small single-copy region (LSC and SSC), separated by two copies of inverted repeats (IRa and IRb). The genome contains 139 protein-coding genes (PCGs), 3 kinds of ribosomal RNAs (rRNAs), and 29 transfer RNAs (tRNAs) genes that are typical of Saccharina cpDNA. A phylogenetic analysis strongly supported the close phylogenetic affinity of S. latissima and Saccharina japonica. The complete cpDNA of S. latissima will provide valuable molecular data for further analysis of evolutionary and conservation genetic resources.

 抽象的

Saccharina latissima是一种褐藻（褐藻纲），属于海带科。我们报道了阔叶S. latissima完整叶绿体基因组的从头组装和注释。 S. latissima的环状 cpDNA 长度为 130,619 bp，具有一个大的和一个小的单拷贝区域（LSC 和 SSC），由两个反向重复拷贝（IRa 和 IRb）分隔。基因组包含 139 个蛋白质编码基因 (PCG)、3 种核糖体 RNA (rRNA) 和 29 个糖精cpDNA 典型的转移 RNA (tRNA) 基因。系统发育分析有力地支持了S. latissima和Saccharina japonica的密切系统发育亲和力。宽阔蝽完整的cpDNA将为进一步分析进化和保护遗传资源提供有价值的分子数据。
