Our report on the first finding of Dickeya undicola in sweet potato from South America is online! apsjournals.apsnet.org/doi/10.1094/...
I should have said, this takes us to about 2.8 million genomes in total. We don't have annotations, etc for the latest data yet, this will be an ongoing process
Be part of OMGN! Open to all researchers with an interest in oomycetes, from molecular genetics & genomics to biology, population biology, and ecology, at either an experimental or a computational level. Investigators new to the field are always welcome oomycetes.com
#transgenerational transmission of a core #microbiome that protects against downy mildew from soil to #phyllosphere

🧫🦠🌱 The countdown for the 8th International Bacterial Wilt Symposium has started!
We are very excited to present the tentative program for the 8th IBWS2026

Finally, this paper shows the strength of international collaboration. Pathogens do not respect national borders, our data shouldn't either. As Covid has shown, making genomic data publicly available is vital for effective tracking and understanding of pathogen evolution. (7/7)
We conclude that phytosanitary measures should focus on preventing the entry of infected plant material. Phy I is not widespread in Europe yet. Once phy I becomes more established, eradication or containment would be extremely challenging, if not impossible. (6/7) link.springer.com/article/10.1...
So these findings were clearly linked to several introduction events. "Rose" clade isolates seem to be quite persistant in the environment (in surface water and bittersweet), see also doi.org/10.1094/PDIS.... This poses a risk for agriculture in Europe (5/7)
The "Rose" isolates were found in rose, potato, bittersweet and surface water. The "Ginger" strains were isolated from Zingiberaceae plants (Curcuma spp. and Ginger). Two isolates from tomato in Italy formed a separate clade and were closely related to two strains from Bangladesh. (4/7)

Mostly, these were from European findings between 2015-2024. We compared them using ANI and core genome MLST analyses. We could determine that there are number of different introductions. We identified two major clades, the "Rose" and a "Ginger" clade. (3/7)
Furthermore, we wanted to elucidate the genetic relatedness of European isolates. We contacted colleagues from Belgium, Germany, Greece, Hungary, Italy, Poland, Slovenia, and Switzerland to share their isolates with us. We compared 62 phy I isolates (59 sequenced in for this paper). (2/7)
We have a new paper out 🧵, link.springer.com/article/10.1...
In recent years, Ralstonia pseudosolanacearum phylotype I (phy I) has been found across Europe, affecting crops from 🌹 to 🥔. We analyzed the genetic diversity of phy I in Europe to try to learn something about its origins. (1/7)
Fig. 1. The extended plant immune system. Schematic overview integrating key elements of classical plant immunity with microbiome-mediated protection, as discussed in this review. PTI, pattern-triggered immunity; ETI, effector-triggered immunity; SAR, systemic acquired resistance; ISR, induced systemic resistance; PGPR, plant growth-promoting rhizobacteria.

Excited to share that PNAS published our research article focused on "Why are Ralstonia goofy?"

De Nederlandse versie is de herziene vertaling (druk uit 2000), gelezen voordat de films uitkwamen. Later, rond 2004 de Engelse versies gekregen, die duidelijk meer gelezen, afgelopen maand na 15 jaar weer eens herlezen.

Our national science & research agency is now facing more job cuts than under Tony Abbott
Call on the Albanese Govt to fund the scientists & research we need to tackle big issues we face from climate to food security and everything in between

In my previous lab this method was often used as a cheap alternative to commercial kits: bmcresnotes.biomedcentral.com/articles/10.... but don't know how well it would translate to your samples
