RNA splicing generates a functionally specialized Rep protein isoform in geminiviruses — enabling timely control of the viral cycle. Strikingly, similar strategies might have evolved in DNA viruses infecting different kingdoms: www.biorxiv.org/content/10.6... Spearheaded by @delphinem-p.bsky.social!

SAMPL-seq reveals micron-scale spatial hubs in the human gut microbiome - Nature Microbiology Split-And-pool Metagenomic Plot-sampling sequencing (SAMPL-seq) can be applied to complex microbial communities to reveal spatial co-localization of microbes at the micron scale.

Proximity between microbes can hold a lot of information about how they interact.

Really cool study from @harriswang.bsky.social showing how Spatial Sequencing can be used to deduce more from the microbial world by understanding physical proximity.

Really cool work!

"All T6SS-inducing regulators are equal, but some regulators are more equal than others".
Preprint 🚨: We use #Vibrio to show that #T6SS activation by regulator manipulation may result in the expression of different effector repertoires, affecting toxicity 🦠

A new paper from the lab on virus-like particles called eCISs www.nature.com/articles/s41...

How bacteria evolved thousands of precision nanoinjectors?

Some bacteria don’t secrete toxins — they inject them using phage-derived machines called extracellular contractile injection systems (eCISs).

Preprint: Here we report a glass bead-based system suitable for the *simultaneous monitoring* of Arabidopsis root exudate and root microbiome dynamics. Teaser: some link between glucosinolates ~ SynCom composition. Happy reading. Credits to Charlotte Joller et al.! www.biorxiv.org/content/10.6...

Check out our new preprint using 30 SynComs covering a phylogenetic diversity gradient, we uncover many interesting strain and community features involved in seed to seedling bacterial transmission 🧫🌱

Independent, ongoing clade-specific expansions of IS5 elements in Pseudomonas syringae Insertion sequence (IS) elements are transposable regions of DNA present in a majority of bacterial genomes. It is hypothesized that differences in distributions of IS elements across bacterial strain...

Hey y’all,

New paper out from the lab in Microbial Genomics, starting down the rabbit hole of IS elements in Paeudomonas syringae

www.microbiologyresearch.org/content/jour...

Result 1) you can see from complete genomes that there’s been multiple independent expansions of IS5 and we don’t quite know why

Result 2) ~50% of the (>100 copies) of IS5 elements differ in location between nearly identical genomes

Result 3) IS5 from can hotwire gene expression

Our lab at @TheSainsburyLab is recruiting a pre-doctoral intern to work on plant immunity research. Ideal for those who are planning to pursue a PhD and seeking research experience. tatsuyanobori.com

Preprint: Systematic discovery of TIR-based immune signaling systems in bacteria

Conservation of TIR-derived signals accross the tree of life! We found bacterial TIR immune systems that signal via canonical cADPR (like in humans) and 2'cADPR (a plant immune signal).

Documented 11 Thoeris types

Congrats !!!
Great thread, and even better story

Excited to share our new @natecoevo.nature.com
paper. We identified microbes found across nearly all ruminants that act as the functional backbone of both the rumen ecosystem and the host, with major implications for food security and climate change mitigation. (1/8)

Beautiful work

A single-cell, spatial transcriptomic atlas of the Arabidopsis life cycle - Nature Plants This study presents an extensive single-nucleus and spatial transcriptomic atlas of the Arabidopsis life cycle that represents ten distinct developmental time points inclusive of six diverse organs.

From a gene’s single cell expression–through spatial localization–to novel function, and beyond!
Now out @natplants.nature.com
We built a comprehensive spatial-transcriptomic atlas of Arabidopsis, revealing cell-type identities across organs in unprecedented detail

@shanice-webster.bsky.social looks at iron status in plant-microbiome interactions. Proteobacteria and firmicutes are typically balanced in the microbiota, but iron starvation can really mess with that, going to dysbiosis. Used “mfec” Arabidopsis quadruple mutant.
