Hoy celebramos el Día Internacional de la Mujer y la Niña en la Ciencia visibilizando algo cotidiano en nuestro grupo: hacer ciencia en un equipo lleno de referentes femeninos.

Es clave crear espacios donde las cientificas puedan liderar, investigar e inspirar.

III) IG catabolic product: do you refer to the I3Acetate or the 3Acetaldehyde or ...? The Acetaldehyde is difficult to square, we think it is of bacterial origin (bacterial Auxin precursor); we see this only induced in exudates and it is already present in absence of plants (only the SynCom).

I) clay vs. glass absorption: Yes, our worry is that surface properties of soil particles will strongly affect recovery of metabolite profiles.
II) Nitriles or ITS: not specifically recovered by our approach (maybe an annotation issue)

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...

Soil iron drives beneficial maize microbiome feedbacks in rotations with wheat Background: Plants change their surrounding soil microbiome by root exudates and such conditioned microbiomes impact the performance of the present as well as the next plant generation as for example ...

Preprint: We identified soil iron levels as critical factor explaining the variation in soil microbiome feedbacks on plant growth. The soil microbiomes tend to provide more beneficial feedbacks at low levels of soil iron. Happy reading.

Evolutionary trade-off between stomatal defense and gas exchange in Brassicaceae Kang et al. show that coronatine hijacks the ABA hydroxylase CYP707A1 in A. thaliana to override stomatal defense. While CYP707A1 also enables rapid light-induced stomatal opening, C. rubella and E. s...

Our ten years of work is finally out in Current Biology! We reveal a new mode of action of the bacterial phytotoxin coronatine produced by Pseudomonas syringae. www.cell.com/current-biol...

Clarivate highlights every year individual researchers as #HighlyCited2025. However and to make this clear: such a recognition is a team’s effort. ALL credits and glitter [✨] go to my GREAT TEAM, colleagues and collaborations who contributed with work, writing and spreading our studies!

A vinyl box with six colored vinyl LPs sticking out of its right side. The Title "Guns in Rosettes" is on top, with the subtitle "The Arabidopsis chemical weapons arsenal" just below. Then there is an Arabidopsis plant with machine guns sticking out. Below is the statement "6-LP LIMITED EDITION COLORED VINYL BOX SET"

The back cover of the vinyl box set showing the tracklist: 1. Methionine-derived compounds Aliphatic GSLs 2. Tryptophan-derived compounds (trptonites) Indolic GSLs Camalexin Hycanite (4-OH-ICN) 3. Phenylalanine-derived compounds (phenylpropanoids) Benzenic GSLs Coumarins Hydroxycinnamates Flavonoids 4. Terpenoids (E)-β-caryophyllene α- and β-pinene Thalianin, arabidin, and DMNT And the statement "Recorded live in front of an audience in 2025"

Our article "Guns in Rosettes: The Arabidopsis chemical weapons arsenal" is finally published @plantphys.bsky.social!

Six years ago, I started at the MPIPZ with a head full of ideas. What a journey. I’m thrilled to share that, from Jan 2026, I will be moving to Zurich as a chaired associate professor at the University of Zurich.
A new chapter, and plenty of roots still to grow. Can’t wait for the adventure ahead!

Congratulations Tonni🍻 Gonna miss you

updated preprint: Intriguingly, Arabidopsis responded with both, improved growth and enhanced defence to a maize-conditioned soil microbiome, and this dual microbiome feedbacks were mediated by priming of the defences. Credits to Katja Stengele et al.!

SynCom of maize root bacteria: in team work, they detox differently. Interacting they redirect the metabolisation to an alternative degradation product.

Updated preprint: MMF1 is "a microbiota receptor” through which Arabidopsis plants perceive their soil microbiome. Perception optimises root microbiome composition, immune status and ultimately leads to better growth. www.biorxiv.org/content/10.1...
