Such an honor to be a part of this amazing team!

Finally published!
Our new study in Curr Biol @currentbiology.bsky.social analyzes how CYP707A1 promoter variation drives an evolutionary trade-off between stomatal defense and gas exchange across Brassicaceae species.

By combining molecular genetics with cell-ablation experiments, we found that vascular cambium stem cells and xylem-identity cells form an interchangeable unit, a stem cell niche.

Was great visiting Ka-Wai @kawaima.bsky.social at Academia Sinica, Taiwan. Thanks for having me and for all the joyful, fruitful, and productive discussions!!

New members in the lab! RTNakanoLab is growing and is eager to explore the frontiers in the field of plant-microbiota interactions. If you are interested on joining us, do not hesitate to let us know!

Riyohei Thomas Nakano (@luckystrike1984.bsky.social) is presenting new work about the mechanisms of disease suppressive microbes. Have identified AhcY mutant and looking into downstream effects.

Microbiome session at #2025ISMPMI: @dorruss12.bsky.social kicks off the session.
Using barcoded mutant libraries, he identified bacterial colonization genes.
Among them was an efflux pump family - hypothesize that they help commensals survive glucosinolate breakdown products during plant defense.

It was lovely to meet and share what we’ve been up to! Happy to be part of Nakano lab alumni! 🤗

JSPS Research Fellowship The Japan Society for the Promotion of Science (JSPS) Research Fellowship supports you as a highly qualified postdoc from Germany in conducting your research in Japan – regardless of discipline.

Hey my fellow Germans! I wasn't aware, but there is an AvH-JSPP postdoc fellowship, dedicated to German citizens aiming to do their postdoc in Japan. It covers salary + travel to Japan + startup for your life in Japan. Let me know if you are interested!

RTNakano Lab Reunion - it’s always good to see the former members of the lab enjoying their life. Gözde and Zoe are doing their PhD with Stan Kopriva and Bart Thomma, stay tuned for their upcoming work!!

Had a great time at MPI-MP Golm - thanks a lot for having me, Marco @incavirus.bsky.social !! Now heading back to Köln to get ready for the IS-MPMI Congress…

I'm thrilled to have the chance to give a talk at Yang and Paulo's concurrent session at the IS-MPMI Congress@Köln. It was a last-minute change, and I'm not on the online program yet, but I will be there to introduce our current work on host immune manipulation by commensals!

I’m not really living in Bluesky and only spontaneously visiting. I heard there’s no political BS but only peaceful and productive scientific chats. Now i do see a number of DJT photos on my timeline…

Oh by the way, did you know that you can you the #EMBO fellowship to do your postdoc? The condition is that you move to Japan from one of the EMBO member countries. Give it a thought! www.embo.org/funding/fell...

Listening to @incavirus.bsky.social 's inspiring and exciting talk. Vertical transmission of virus is regulated by AGO, while I’m curious about its impact on the fitness of the entire holobiome!

Already submitted an abstract to IS-MPMI Congress, and now I have registered and paid the registration fee. Wait for me Cologne, I am coming back!!

So far my best favorite paper in 2025

And here’s the kicker: this specialization helps bacteria spread! Flagella-equipped bacteria exit the infected tissue, ready to colonize new areas. This coordinated strategy is crucial for the pathogen's success.

Individual bacteria specialize, some suppress immunity while others escape early to spread infection before the plant tissue collapses. It's a division of labor!

The study highlights how phenotypic heterogeneity allows pathogens to adapt to host environments dynamically.

Pseudomonas syringae subpopulations cooperate by coordinating flagellar and type III secretion spatiotemporal dynamics to facilitate plant infection Nature Microbiology - Single-cell gene expression analysis reveals phenotypic heterogeneity to enable bacterial specialization over the course of plant colonization.

How Bacteria Outsmart Plants—Then Flee the Scene!

Our new research in Nature Microbiology uncovers the sophisticated teamwork of Pseudomonas syringae, a notorious plant pathogen.

A line graph titled "Confirmed cases of influenza B Yamagata" shows weekly confirmed cases of B Yamagata influenza worldwide from various types of influenza surveillance. The vertical axis represents the number of cases, ranging from zero to 5,000, while the horizontal axis covers the years from 2013 to 2025. The graph indicates significant fluctuations in case numbers over the years, with a noticeable peak just below 5,000 cases around 2019, followed by a steep decline. A data source note mentions that only a fraction of potential influenza cases is tested by labs for confirmation and strain identification. The data comes from FluNet, World Health Organization, and is dated 2023. The graph is licensed under CC BY.

I am happy to introduce this bioRxiv. Stomatal opening is crucial for gas exchange, but it unavoidably offers invasion by pathogens. We found that by coronatine (COR), Pto DC3000 exploits CYP707A1 activation in Arabidopsis thaliana, encoding an enzyme that degrades ABA, for stomatal invasion.
