Dec 1, 2022 · The lysing of heterotrophic and autotrophic bacteria contributes to nutrient availability in marine ecosystems by what is known as the ‘viral shunt’ of the ‘microbial loop’, which is exploited by other heterotrophs 2, 3. Evidence of ocean KtW includes flavophages that bloom with their Flavobacteria hosts [4].
Dec 1, 2020 · The ecological role of bacteriophages has an effect on bacterial existence, diversity in the ocean, biogeochemical cycles, re gulation of nutrients and they are the key. players of horizontal...
Feb 5, 2020 · This suggests that phages are implicated in the rise of pathogens in disturbed marine ecosystems. Bacteriophages encode genes that modify bacterial functions during infection. The acquisition of phage-encoded virulence genes is a major mechanism for the rise of bacterial pathogens.

Aug 9, 2021 · Given that bacteria account for ~15% of the global biomass on Earth 7, it is becoming clear that phages have an important role in the functioning of many ecosystems and, on a larger scale, have...

Jul 24, 2014 · Viral abundance generally increases with the increasing productivity of aquatic ecosystems and, as a consequence, decreases from freshwater to marine ecosystems, from costal to oceanic zones, and from the surface to the bottom of the euphotic layer (Sime-Ngando and Colombet, 2009).
greatest abundance and highest genetic diversity in marine ecosystems, and the vast majority of them are bacterio-phages, which is a key factor dominating the mortality of microorganisms. Through phage infection, horizontal gene transfer, and inducement of bacterial phage-resistant muta-tions, marine viroplankton play important roles in regulating
