we now have an issue too..... Viral NblA proteins negatively affect oceanic cyanobacterial photosynthesis www.nature.com/articles/s41...

Viral NblA proteins negatively affect oceanic cyanobacterial photosynthesis - Nature
Viral NblA accelerates the cyanophage infection cycle, directs degradation of the host phycobilisome and other proteins, and reduces host photosynthetic light-harvesting efficiency.

Metabolic redundancy is required for microbial polyethylene assimilation.

Do you know who Douglas Prasher is? Many don't, even though he is the person who cloned the original #GFP gene in the late 1980s. In my short history of plant light #microscopy I also cover a bit of his story - & why he is relatively unknown today, despite the importance of his work. See this 🧵👇

There are 1000x less microbes able to degrade biodegradable plastics (i.e. aliphatic polyesters) in marine environments (sediments) than in their terrestrial counterparts! 🤯 Why? Still don't know🤔 (fig shows log10 values). Check our latest preprint doi.org/10.1101/2024...
