Bacteriophage continue to have so much to teach us. It's in our interest to understand how they work and impact human & environmental health. New joint work led by @mariandm.bsky.social & @rantahan.bsky.social inferring single-cell latent period & burst size heterogeneity from population dynamics.

Dr. Jozef Nissimov and his team have uncovered a genome of a cyanophage (a virus that infects cyanobacteria) that defies conventional distinctions between viruses and cells.

#PhageSky #ProtistsOnSky endosymbionts have "their" phages, too. cyanos of sponges (below), 𝘞𝘰𝘭𝘣𝘢𝘤𝘩𝘪𝘢 of insects, and then we have the piñata 👇 schaechter.asmblog.org/schaechter/2...
Putative interactions between the MAnky­pha­ge, two bacterial endosymbionts (M. polyxenophila and G. numerosa), and the cryptomonad host. C. gyro­py­renoidosa harbors 4 genomes (in green): nuclear, mi­tochondrial (MT), nucleomorph (NM), and plastid. Mo­bile elements are found in the endosymbionts' chromo­somes and plasmids, particularly in M. polyxenophila. Only G. numerosa encodes a flagellum, but both endosymbionts have type IV secretion systems (T4SS) and ATP/ADP translocases. The endosymbionts and phage also encode eukaryotic-like protein domains like ankyrin repeats (ANKs) and leucine-rich repeats (LRRs). Other putative eukaryotic interactions include the MAnkyphage-encoded protein (DUF3685) with homo­logy to response regulators in plastids and cyanobac­teria. MAnkyphage harbors a type II toxin‑antitoxin system present in M. polyxenophila. The tally of gen­omes in this single-celled cryptomonad comes to 7 plus 3 bacterial plasmids.
