This is such a cool paper as it experimentally addresses the role of the auxiliary metabolic gene nblA in cyanophages showing a large benefit of NblA to the cyanophage and a negative effect on the host photosynthetic apparatus and host photosynthesis

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.

@naturalist1986.bsky.social has done it again, this time with 3rd prize at the ISPS meeting in the beautiful Sde Boker. Poster title: A rhizobial trickster: Legume symbiont simultaneously fixes atmospheric nitrogen and denitrifies. Time to turn these posters into manuscripts.

In plant-pathogen or plant-microbe interactions what is the proper null.
- there is specific coevolution of any pathogen/microbe such that it was at least partly adapted to the host isolated.
-the host of isolation may have not effected the pathogen in the slightest.
