Complete sequence and analysis of plastid genomes of Pseudo-nitzschia multiseries (Bacillariophyta)

Abstract

Pseudo-nitzschia multiseries are common members of phytoplankton communities, which can bring about blooms in coastal and ocean. Meanwhile, the neurotoxin was produced by this species can cause amnesic shellfish poisoning in both marine mammals and human beings. Whereas the lacking of plastid genome information on this species obstacles the study of its evolutionary position. Here, the complete plastid genome sequence of Pseudo-nitzschia multiseries is presented. The genome is a circular DNA composed 111 539 bp of with one rRNA operon. The average G + C content of this plastid genome is 31.37%. This genome includes 96 protein coding genes (containing four unidentified open reading frames), 27 transfer RNA genes, three ribosomal RNA genes, and one tRMA. The comparison between P. multiseries and Thalassiosira pseudonana has a high similarity in gene content and structure. In addition, our phylogenetic result suggests that the P. multiseries is the sister group of T. pseudonana.
