So -- What are Ralstonia and why are they goopy?
Ralstonia are bacterial pathogens of plants. They colonize and clog the water-transporting xylem vessels, causing rapid-onset wilt disease—they can fatally wilt plants within days.
This timelapse by Jonathan Jacobs shows a sped-up time-course.

This is the end of my journey at @irhs-angers.bsky.social as a post-doc 🎓 Thank you so much @emersys-irhs.bsky.social for hosting me during the two last years and helping me to develop more🔬 Scientific products of our projects on the T6SS biology of Stenotrophomonas rhizophila are coming 👀

Check our new perspective paper exploring how the seed holobiont goes to sleep 😴 and reactivate for germination.
A lot of exciting research to be done to understand dormancy mechanisms in microbes and plants ☘️

This paper solves the puzzle that I wrote about in my chapter 5 / future directions of my PhD thesis!
It's really interesting what comes out of these in planta experimental evolution studies

Disruption of putrescine export in experimentally evolved Ralstonia pseudosolanacearum enhances symbiosis with Mimosa pudica | mBio
Rhizobia, the nitrogen-fixing symbionts of legumes, emerged through repeated and independent
horizontal transfers of some essential symbiotic genes. However, these transfers alone

An unexpected mechanism for population heterogeneity in the gut microbiome:

A commensal bacterium secretes effector proteins to establish population heterogeneity in the gut
Zagieboylo and colleagues demonstrate that the human commensal Bacteroides thetaiotaomicron
secretes two self-targeting proteins that induce heterogeneity within its own population.
