Seasonal Enhancement of the Viral Shunt Catalyzes a Subsurface Oxygen Maximum in the Sargasso Sea

Naomi E. Gilbert, Daniel Muratore, Camelia Shopen Gochev, Gary R. LeCleir, Shelby M. Cagle, Helena L. Pound, Christine L Sun, Alfonso Carrillo, Kimberley S Ndlovu, Ilia Maidanik, Ashley R. Coenen, Lauren Chittick, Jennifer M. DeBruyn, Alison Buchan, Debbie Lindell, , Steven W. Wilhelm

The paper identifies viral shunt activity as a driver of seasonal subsurface oxygen maxima in the Sargasso Sea by linking elevated cyanophage activity and bacterial catabolism.

Mitomycin C eliminates cyanobacterial transcription without detectable lysogen induction in a Microcystis-dominated bloom in Lake Erie

Robbie M. Martin, Elizabeth R Denison, Helena L. Pound, Ellen A. Barnes, Justin D. Chaffin, Steven W. Wilhelm

The paper tests lysogeny in Microcystis blooms using mitomycin C and finds it ineffective for inducing prophage, suggesting standard protocols are unsuitable for freshwater cyanobacterial studies.

Lysogen formation governs colonies while lytic infection is more prevalent in single cells of the bloom-forming cyanobacterium, Microcystis

Xuhui Huang, Emily E. Chase, Brittany N. Zepernick, Robbie M. Martin, Lauren E. Krausfeldt, Helena L. Pound, Hongyan Wu, Zheng Zheng, Steven W. Wilhelm

This study examines how colony formation in Microcystis affects viral infection strategies, finding that colonies favor lysogeny while single cells experience more lytic infection.
