Persistent Intra-Specific Variation in Genetic and Behavioral Traits in the Raphidophyte, Heterosigma akashiwo
Motility is a key trait that phytoplankton utilize to navigate the heterogeneous marine environment. Quantifying both intra- and inter-specific variability in trait distributions is key to utilizing traits to distinguish groups of organisms and assess their ecological function. Because examinations of intra-specific variability are rare, here we measured three-dimensional movement behaviors and...
متن کاملEvolution and Phylogeny of Large DNA Viruses, Mimiviridae and Phycodnaviridae Including Newly Characterized Heterosigma akashiwo Virus
Nucleocytoplasmic DNA viruses are a large group of viruses that harbor double-stranded DNA genomes with sizes of several 100 kbp, challenging the traditional concept of viruses as small, simple 'organisms at the edge of life.' The most intriguing questions about them may be their origin and evolution, which have yielded the variety we see today. Specifically, the phyletic relationship between t...
متن کاملComplete Genome Sequence of a Phycodnavirus, Heterosigma Akashiwo Virus Strain 53
We report the complete genome sequence of Heterosigma akashiwo virus strain 53. The virus is a member of the Phycodnaviridae, one of the families regarded as giant double-stranded DNA viruses. The 274,793-bp genome contained 246 protein-coding and 3 tRNA-coding sequences.
متن کاملIsolation of a virus infectious to the harmful bloom causing microalga Heterosigma akashiwo (Raphidophyceae)
A virus infecting the harmful bloon~ causing microalga Heterosjgma akashiwo (Raphidophyceae) was isolated from the coastal water of Nomi Bay, Japan, In July 1996. The isolate caused lysis in 2 strains of H. akashiwo tested and numerous virus-like particles (VLPs) appeared in the lysed algal culture, whereas virus multiplication was not detected in the healthy culture of H. akashiwo without its ...
متن کاملApplication of fluorescence in situ hybridization (FISH) method to detect Heterosigma akashiwo
Species-specific probes against cytoplasmic rRNA and nuclear rDNA of Heterosigma akashiwo were designed on the basis of LSU and ITS sequences. FISH protocols for whole cell and nuclear were established to detect this alga. The results showed that the rRNA-targeted probe hybridized with cytoplasmic rRNA, showing strong green fluorescence throughout the whole cell, while cells labeled by rDNA-tar...
