Monoacylglycerides from the Diatom Skeletonema marinoi Induce Selective Cell Death in Cancer Cells

Genome Sequence of Roseovarius mucosus Strain SMR3, Isolated from a Culture of the Diatom Skeletonema marinoi

We present the genome of Roseovarius mucosus strain SMR3, a marine bacterium isolated from the diatom Skeletonema marinoi strain RO5AC sampled from top layer sediments at 14 m depth. Its 4,381,426 bp genome consists of a circular chromosome and two circular plasmids and contains 4,178 coding sequences (CDSs).

Domoic Acid Improves the Competitive Ability of Pseudo-nitzschia delicatissima against the Diatom Skeletonema marinoi

Because domoic acid, a neurotoxic secondary metabolite produced by marine diatoms in the genus Pseudo-nitzschia, is hypothesized to be part of a high affinity iron uptake system, we investigated whether domoic acid could improve the competitive ability of Pseudo-nitzschia delicatissima, and whether the availability of iron changed the outcome of competition experiments. We found that domoic aci...

Nitrate Utilization by the Diatom Skeletonema costatum

Nitrate uptake has been studied in nitrogen-deficient cells of the marine diatom Skektowema costatum. When these cells are incubated in the presence of nitrate, this ion is quickly taken up from the medium, and nitrite is excreted by the cells. Nitrite is excreted following classical saturation kineffcs, its rate being independent of nitrate concentration in the incubation medium for nitrate co...
