DOI: 10.1038/s41467-018-07496-0
Abstract: A broad diversity of sex-determining systems has evolved in eukaryotes. However, information on the mechanisms of sex determination for unicellular microalgae is limited, including for diatoms, key-players of ocean food webs. Here we report the… read more here.

DOI: 10.1080/09670262.2019.1620342
Abstract: ABSTRACT We confirm an amnesic shellfish poisoning risk associated with domoic acid production by the species Pseudo-nitzschia plurisecta and determine the toxin profile, which includes three domoic acid isomers. Although the species was reported once… read more here.

DOI: 10.1111/1462-2920.16242
Abstract: The exchange of metabolites mediates algal and bacterial interactions that maintain ecosystem function. Yet, while 1000s of metabolites are produced, only a few molecules have been identified in these associations. Using the ubiquitous microalgae Pseudo-nitzschia… read more here.
