The distinction between virulent & temperate phages gets fuzzier if one can find so many virulent phages in the sequences of bacterial genomes coming from standard lab "pure" cultures. Check Peter's thread on our work and the N&V by Carson & Hynes: doi.org/10.1038/s415...

How do root #microbes respond to drought? This study finds that #Streptomyces responses are strain-specific & functionally diverse, with traits & #plant effects varying independently of phylogeny, stressing the need to resolve functional traits at the strain level @plosbiology.org 🧪 plos.io/4owtjIT
Pangenomic visualization of the genomic organization of all 12 Streptomyces isolates representing each of the four AC groups. Hierarchical clustering is based on orthogroup presence/absence using Euclidean distance and Ward’s linkage method. Colored rings show orthogroup presence/absence per isolate, the outer ring shows the number of contributing genomes, and the second outer ring shows the number of genes present in each orthogroup. The metadata table shows 1) experimental phenotype data (orange) of total siderophore production (SP, halo size on CAS-LB media), growth under osmotic stress (OST, 1.0M sorbitol), and the relative production of four individual siderophores in response to media supplemented with drought- vs. well-watered root tissue (EF1 and EF2, ferrioxamine EF; H, O-methyl desferrioxamine H, D4, derrioxamine D4), and 2) genome analysis data (dark blue), showing the number of gene copies that match with specific COG function search terms related to iron acquisition (iron and Sid, siderophores), carbon resource utilization (G-3-P, glycerol-3-phosphate), and osmotic stress response (ProP, FabG, OmpR, Kdp, Trk). Scale values represent Z-scores, where darker blue indicates more gene copies, and darker orange indicates more siderophore production, more growth under osmotic stress, or a larger halo.
