Provirus induction diversifies adaptive variation in Pseudomonas aeruginosa lysogen populations Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen that forms chronic infections in people with cystic fibrosis. Often P. aeruginosa strains are lysogens, infected with proviruses, that ...

Happy new year! The second big project of my PhD in Rachel Whitaker's lab is now up! 🎉 We look at how provirus infection affects the evolution of the bacterial chromosome with different types of viral induction – with CRISPRs or antibiotics. Take a peek 🦠 www.biorxiv.org/content/10.6...

(Part 1 of 2) Love your weird lakes! ⛰️🦐 Made this little comic for fun after some recent visits up north.

Wow that sounds like a cool paper! Everyone should read it! (it's mine it's my paper 😁)
thrilled to announce that it's on BioRxiv now!! Anyone who is interested in the uncultivated majority, cool microbes, and eco-evolutionary dynamics should give it a read!!

16S rRNA is just like AI.
If you don't know how to use it, just don't, or train first.

Ok scientists. How do we respond? Scientific strike starting on Monday? Something has to be done to let people know what is going on.

ASM did a spotlight article on me last February and it has also been taken down as “under review”. Other spotlight articles are still up so not sure how else to interpret this besides the obvious. It feels pretty crappy to have been singled out and I won’t be engaging with them in the future.

My letter to ASM leaders that I sent is too long to be posted here, so I'm going to post highlights in case anyone else needs information for their letter. 🧵

Kudos to @asm.org I have never in my nearly 25yrs as a member been sent an "ASM Action Alert" asking me to contact my members of Congress. Make those calls. Write those emails.

There are extraordinary times and we must make ourselves heard

Led astray by 16S rRNA: phylogenomics reaffirms the monophyly of Methylobacterium and lack of support for Methylorubrum as a genus Abstract. Although the 16S (and 18S) rRNA gene has been an essential tool in classifying prokaryotes, using a single locus to revise bacteria taxonomy can

Spread the word! Methylorubrum is no more! Thread below (1/4):

High-quality PacBio draft genome sequences of 17 free-living Bradyrhizobium and four related Nitrobacteraceae strains isolated from arid soils in the Santa Catalina Mountains of Southern Arizona. Non-symbiotic Bradyrhizobium are among the most abundant and ubiquitous microbes in bulk soils globally. Despite this, most available genomic resources for Bradyrhizobium are derived from plant-associ...

Not all Bradyrhizobium fix N2! In fact, most that live in soil probably don’t. We isolated a bunch from Arizona soils and found none had N-fixing or nodulation genes. We report their genomes and phylogeny here in an accepted paper at access microbiology! www.microbiologyresearch.org/content/jour...

I made ,some time ago, a starter pack for Microbial #Symbiosis. I'm 100% sure it's incomplete, but short on time lately... You can reply and suggest prople/feeds/etc to add!
