Mitochondrial Genome Sequences of Four Strains of the Bloom-Forming Raphidophyte Heterosigma akashiwo

Mitochondrial Genome Sequences of Four Strains of the Bloom-Forming Raphidophyte Heterosigma akashiwo

We report here the complete mitochondrial genome sequences of four strains of bloom-forming raphidophytes from Heterosigma akashiwo These 39-kb sequences contain 42 protein-, two rRNA-, and 26 tRNA-coding sequences. Notable sequence variations were observed among these four newly sequenced and three previously characterized strains, suggesting their potential usage as strain-specific markers.

Chloroplast Genome Sequences of Seven Strains of the Bloom-Forming Raphidophyte Heterosigma akashiwo

We report here the complete chloroplast genome sequences of seven strains of the bloom-forming raphidophyte Heterosigma akashiwo These ~160-kb sequences contain 124 protein-, 6 rRNA-, and 34 tRNA-coding sequences. Notable sequence variations were observed among these seven sequenced and two previously characterized strains.

Effects of salinity structure on swimming behavior and harmful algal bloom formation in Heterosigma akashiwo, a toxic raphidophyte

The formation of toxic surface blooms of the motile raphidophyte Heterosigma akashiwo often occurs too quickly to be attributed to cell reproduction. Rapid appearance of surface blooms is more consistent with the hypothesis that a dispersed cell population aggregates at the surface due to a combination of physical factors and swimming behavior. Because of the frequent association of Heterosigma...

A hypervariable mitochondrial protein coding sequence associated with geographical origin in a cosmopolitan bloom-forming alga, Heterosigma akashiwo.

Geographical distributions of phytoplankton species can be defined by events on both evolutionary time and shorter scales, e.g. recent climate changes. Additionally, modern industrial activity, including the transport of live fish and spat for aquaculture and aquatic microorganisms in ship ballast water, may aid the spread of phytoplankton. Obtaining a reliable marker is key to gaining insight ...
