We report the chloroplast genome sequence of , a tiny araphid pennate diatom collected from the Adriatic Sea. The 160,994-bp . genome displays a quadripartite structure and its gene repertoire resembles those of other diatom chloroplast genomes. Besides the genes located in the inverted repeat, is duplicated. A gene-poor region in the large single-copy region contains multiple ORFs sharing sequence similarities with plasmids and chloroplast ORFs found in other diatom species. The genome features a single intron, a group II intron in . Phylogenomic analysis identified at a basal position within the araphid 2 clade.
我们报告了从亚得里亚海收集的一种微小的无壳 pennate 硅藻的叶绿体基因组序列。160,994 碱基对的该基因组呈现四分体结构，其基因组成与其他硅藻叶绿体基因组相似。除了位于反向重复序列中的基因外，该基因被复制。大单拷贝区域中的一个基因贫乏区域包含多个与其他硅藻物种中发现的质粒和叶绿体开放阅读框具有序列相似性的开放阅读框。该基因组具有一个内含子，即该基因中的一个 II 型内含子。系统基因组分析确定该物种处于无壳硅藻 2 进化枝的基部位置。
