Abstract

Macrocystis sp. isolate 501 is a brown algae in the family Laminariaceae. Here, we sequenced, assembled, and annotated the complete chloroplast (cp) genome of Macrocystis sp. isolate 501. The cp genome of Macrocystis sp. isolate 501 is 130 103 bp in length with a GC content of 30.86%. The assembled genome has a typical cyclic structure, containing a large single-copy (LSC) region of 76 397 bp, a small single-copy (SSC) region of 42 856 bp, and a pairof inverted repeatregions(IRs) of 10 850 bp. The cp genome contains 140 unique genes, including 105 protein-codinggenes, six rRNA genes, and 29 tRNA genes. Phylogenetic analysis showed that Macrocystis sp. isolate 501 was closely related to Phaeophyceae. The chloroplast sequence of this species was aligned on NCBI, and the highest coverage was Macrocystis pyrifera (99.18%). Macrocystis pyrifera, also known as the giant brown algae, was first described by the French naturalist Nicolas Duclos in 1750. However, the first detailed description and name of the species was given by the French naturalist Adolphe-Francois Le Jolis in 1863, an article entitled “Étude des Algues littorales de la Manche.” We named the algae we get “Macrocystis sp. isolate 501,” which is the first time that this species has been mentioned. Herein we present the first report on Macrocystis sp. isolate 501 with published genomic information.

大囊藻 501 号菌株的完整叶绿体基因组

摘要大囊藻（Macrocystis sp.在此，我们对大囊藻分离株 501 的完整叶绿体（cp）基因组进行了测序、组装和注释。大囊藻分离株 501 的 cp 基因组全长 130 103 bp，GC 含量为 30.86%。组装后的基因组具有典型的环状结构，包含一个 76 397 bp 的大单拷贝（LSC）区、一个 42 856 bp 的小单拷贝（SSC）区和一个 10 850 bp 的倒置重复区（IRs）。cp 基因组包含 140 个独特的基因，包括 105 个蛋白质编码基因、6 个 rRNA 基因和 29 个 tRNA 基因。系统进化分析表明，501 号分离物中的巨囊藻与辉绿藻科（Phaeophyceae）亲缘关系密切。该物种的叶绿体序列在 NCBI 上进行了比对，覆盖率最高的是 Macrocystis pyrifera（99.18%）。巨囊藻（Macrocystis pyrifera）又称巨褐藻，由法国博物学家尼古拉斯-杜克洛（Nicolas Duclos）于 1750 年首次描述。不过，法国博物学家阿道夫-弗朗索瓦-勒约里斯（Adolphe-Francois Le Jolis）于 1863 年发表了一篇题为 "芒什沿海藻类研究"（Étude des Algues littorales de la Manche）的文章，首次对该物种进行了详细描述并命名。我们将得到的藻类命名为 "大囊藻 501 号分离株"，这是该物种首次被提及。在此，我们首次报告了大囊藻 501 号分离株的基因组信息。
