Another piece of fascinating work done with RCC strains.

Fantastic work done with a very large number of RCC strains.

We have added more than 900 new GenBank sequences to the RCC database that are linked to the web page of the corresponding strains.

The RCC is a partner of @blueremediomics.bsky.social

Transcriptomic response of the picoalga Pelagomonas calceolata to nitrogen availability: new insights into cyanate lyase function | Microbiology Spectrum Vast oceanic regions are nutrient-poor, yet several microalgae thrive in these environments. While various acclimation strategies to these conditions have been discovered in a limited number of model microalgae, many important lineages remain ...

Alexandrium minutum strains from a recombinant cross show correlated allelopathic activity against the diatom Chaetoceros muelleri and the parasite Amoebophrya sp., independent of PST toxicity. Dinoflagellates of the genus Alexandrium can produce bioactive extracellular compounds (BECs) responsible for a wide range of effects on many organism…
