Very nice study from Henshaw et al shows that #marine heterotrophic bacteria can sense and move towards cyanobacteria when the latter are infected with #viruses.

Presumably the signatures of early infection are a sign that nutrients from a lysed cell will be available soon.

This is a nice study that has implications for understanding the role of viruses in the #ocean.

Weekend #Plankton #Factoid 🦠🦐
Research on how bacteria and archaea interact with other members of the plankton food-web is much more advanced in #ocean systems compared to freshwaters, but still very much unknown. They are food, but we also know of many cases of apparent symbiosis between #bacteria and organisms, with bacteria providing bioluminescence, energy via photosynthesis, or B vitamins, but how common is this? Read about the mission here. #science #ClimateChange

Weekend #Plankton #Factoid 🦠🦐

#Copepod #zooplankton are the most numerous metazoans on the planet, and some have evolved into fantastical forms. Take Calocalanus pavo, the beautiful "peacock copepod", which has amazingly plumed antenna and caudal rami. It is small, ~1mm long, and uses the plumes to slow its sinking for feeding in the upper #ocean. It is famous for being very prominent in Ernst Haeckel's Kunstformen der Natur (1904) plate 54 #watercolour paintings of copepoda.

Globally occurring pelagiphage infections create ribosome-deprived cells - Nature Communications

SAR11 bacteria and their phages are abundant in the oceans. Here the authors quantify the number of phage-infected SAR11 cells using microscopy techniques and discover phage-infected cells without any detectable ribosomes.

Daily turnover of active giant virus infection during algal blooms revealed by single-cell transcriptomics

Marine #microorganisms are crucial for #ocean health.

#Bacteria, #archaea, #fungi, #algae and #viruses make up most of the biomass in the seas and form the base of marine food webs.

They support nutrient cycling and drive crucial biogeochemical processes, including key steps in the carbon, nitrogen and silicon cycles.

Ocean modelling must evolve to take their biological complexity into account.

Happy to share a collaborative preprint with Assaf Vardi's group in which we use single cell transcriptomics to link giant viruses with their native hosts during a marine algal bloom!

This approach is quite sensitive - we were able to identify viruses infecting one protist group that made up <0.5% of the community.
