13th Utrecht PhD Summer School​ Environmental Signaling in Plants Aug 24-26 2026 Speakers: Laura Ragni, Roeland Berendsen, Mariana Silva Artur, Matthew Paul, Ari Sadanandom, Beatrice Giuntoli, Bruno Guillotin, Priya Ramakrishna, Caroline Gutjahr, Niko Geldner, Laura Bacete and Marcel Beukeboom.

We are beyond excited to reveal the full line-up for our Environmental Signaling in Plants summer school 2026!

Registration is now open here eps.sites.uu.nl - we look forward to seeing you in Utrecht on 24th-26th August!

Together with a team of great colleagues, we edit a collection titled "Harnessing plant microbiomes to improve performance and mechanistic understanding" nature.com/collections/cg… in the journals @natureportfolio.nature.com @microbiomej.bsky.social . It's open for submission till June 2026.

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.

During Brassicales evolution, plants changed their way to synthesize salicylic acid from PAL pathway to IC pathway.

The time of IC pathway evolution nicely matches our previous publication.

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.
