Bipolar dispersal of red-snow algae [PDF]

Nature Communications, 2018
Red-snow algae are red-pigmented unicellular algae that appear seasonally on the surface of thawing snow worldwide. Here, Segawa et al. analyse nuclear ITS2 sequences from snow algae from the Arctic and Antarctica, identifying dominant phylotypes present

Metabolic relationships between marine red algae and algae-associated bacteria. [PDF]

Mar Life Sci Technol
AbstractMutualistic interactions between marine phototrophs and associated bacteria are an important strategy for their successful survival in the ocean, but little is known about their metabolic relationships. Here, bacterial communities in the algal sphere (AS) and bulk solution (BS) of nine marine red algal cultures were analyzed, and Roseibium and ...

Diarrhetic shellfish toxins production appears to be driven by photosynthesis and phosphate–revealed by different light-adapted strains of Prorocentrum lima complex and P. caipirignum

Frontiers in Marine Science, 2023
IntroductionDiarrhetic shellfish toxins (DST) harm shellfish aquaculture and endanger human health, and include well-known marine dinoflagellate-produced toxins such as okadaic acid (OA) and analogues, such as dinophysistoxin-1 (DTX-1).
