is an important genus of diatoms with many species capable of inducing harmful algae blooms (HABs) in coastal and oceanic waters, some of which produce the toxin domoic acid (DA), a neurotoxin that causes amnesic shellfish poisoning (ASP). is a cosmopolitan species that can induce HABs and produce DA. Nevertheless, mitochondrial genome of has not been revealed. In this study, we determined the complete mitochondrial genome of for the first time. The circular mitochondrial genome was 42,182 bp in length with GC content of 30.37%. It consisted of 65 genes including 39 protein-coding genes (PCGs), 24 tRNA genes, and two rRNA genes. This mitogenome has a group II intron, located in the cytochrome c oxidase subunit genes (), with identified inside the intron region. Phylogenetic analysis revealed that was clustered well with This analysis is valuable for studying the evolutionary relationships among species, and for comparative analysis of strains.
是硅藻的一个重要属，有许多物种能够在沿海水域和海洋水域引发有害藻华（HABs），其中一些会产生毒素软骨藻酸（DA），一种导致失忆性贝类中毒（ASP）的神经毒素。是一种能引发有害藻华并产生软骨藻酸的世界性物种。然而，的线粒体基因组尚未被揭示。在本研究中，我们首次确定了的完整线粒体基因组。环状线粒体基因组长度为42,182 bp，GC含量为30.37%。它由65个基因组成，包括39个蛋白质编码基因（PCGs）、24个tRNA基因和两个rRNA基因。这个线粒体基因组有一个II类内含子，位于细胞色素c氧化酶亚基基因（）中，在内含子区域内鉴定出了。系统发育分析表明与很好地聚类在一起。该分析对于研究物种间的进化关系以及菌株的比较分析具有重要价值。
