【 摘 要 】

Pseudo-nitzschia 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). Pseudo-nitzschia delicatissima is a cosmopolitan species that can induce HABs and produce DA. Nevertheless, mitochondrial genome of P. delicatissima has not been revealed. In this study, we determined the complete mitochondrial genome of P. delicatissima 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 (cox1), with orf790 identified inside the intron region. Phylogenetic analysis revealed that P. delicatissima was clustered well with P. multiseries. This analysis is valuable for studying the evolutionary relationships among Pseudo-nitzschia species, and for comparative analysis of P. delicatissima strains.
