Undermining the cry for help: The phytopathogenic fungus Verticillium dahliae secretes an antimicrobial effector protein to undermine host recruitment of antagonistic Pseudomonas bacteria https://www.biorxiv.org/content/10.1101/2025.06.09.658588v1

Imaging of specialized plant cell walls by improved cryo-CLEM and cryo-electron tomography Cryo-focused ion beam scanning electron microscopy (cryo-FIBSEM) has become essential for preparing electron-transparent lamellae from cryo-plunged and high-pressure frozen specimens. However, targeti...

Cooperation between a root fungal endophyte and host-derived coumarin scopoletin mediates Arabidopsis iron nutrition Iron acquisition is a critical challenge for plants, especially in iron-deficient soils. Recent research underscores the importance of root-exuded coumarins in modulating the root microbiome community...

Curious about my PhD research @parkergroup.bsky.social? The paper is available as preprint on bioRxiv now!
🔬 The interaction between scopoletin and fungal endophyte F80 rescues plant growth under iron-limiting conditions by resolving the iron mobility bottleneck.

Can't say for sure, but our transcriptome suggests that it activates plant immunity on the microbiome where mutants assemble a root community that differs from that of WT. Most likely maintaining microbiome homeostasis in accessions carrying the SNP...

Excited to share my postdoctoral work from Basel! We discovered a “microbiota receptor” in Arabidopsis that optimises plant immunity, the root microbiome composition, eventually leading to enhanced plant growth.

A nucleoside signal generated by a fungal endophyte regulates host cell death and promotes root colonization The intracellular colonization of plant roots by the beneficial fungal endophyte Serendipita indica follows a biphasic strategy, including a host cell…

Soil microbiomes show consistent and predictable responses to extreme events - Nature Soils from 30 grasslands across Europe were subjected to 4 contrasting extreme climatic events under drought, flood, freezing and heat conditions, with the results suggesting that soil microbiomes fro...

Science takes time - a lot of time. Time that is more and more difficult to make available because of increased workloads. Time that exceeds the temporary contracts of postdocs and PhDs.

I'll illustrate this using our paper published in Nature yesterday. 🧵 (1/x)
