DOI: 10.1038/s42003-019-0534-z
Abstract: Iron (Fe) bioavailability limits phytoplankton growth in vast ocean regions. Iron-rich dust uplifted from deserts is transported in the atmosphere and deposited on the ocean surface. However, this dust is a poor source of iron… read more here.

DOI: 10.1111/1462-2920.13934
Abstract: Cytosine methylation has been shown to regulate essential cellular processes and impact biological adaptation. Despite its evolutionary importance, only a handful of bacterial, genome-wide cytosine studies have been conducted, with none for marine bacteria. Here,… read more here.

DOI: 10.1111/1462-2920.14007
Abstract: The diazotrophic cyanobacterium, Trichodesmium, is an integral component of the marine nitrogen cycle and contributes significant amounts of new nitrogen to oligotrophic, tropical/subtropical ocean surface waters. Trichodesmium forms macroscopic, fusiform (tufts), spherical (puffs) and raft-like… read more here.

DOI: 10.1128/msystems.00601-20
Abstract: Trichodesmium erythraeum is a marine cyanobacterium responsible for approximately half of all biologically fixed nitrogen, making it an integral part of the global nitrogen cycle. Interestingly, unlike other nitrogen-fixing cyanobacteria, Trichodesmium does not use temporal… read more here.

DOI: 10.3354/ame01873
Abstract: Contributions of filamentous and picoplanktonic cyanobacteria to the 26 phytoplankton community structure were examined in New Caledonian waters during the 2001-27 2003 El Nino period at three stations. Morphometric characteristics of diazotrophic filamentous 28 cyanobacteria… read more here.

DOI: 10.3389/fmicb.2022.813573
Abstract: Fast repetition rate fluorometry (FRRf) allows for rapid non-destructive assessment of phytoplankton photophysiology in situ yet has rarely been applied to Trichodesmium. This gap reflects long-standing concerns that Trichodesmium (and other cyanobacteria) contain pigments that… read more here.
