Isoprene, the most abundant biogenic VOC, not only shapes atmospheric chemistry but also acts as an airborne signal in short-distance plant–plant communication. #isoprene #PlantResistance

Volatile‐Mediated Plant Defense Networks: Field Evidence for Isoprene as a Short‐Distance Immune Signal Transgenic silver birch (Betula pendula) with altered isoprene emission capacities enhanced pathogen resistance in neighboring Arabidopsis thaliana through a jasmonate-independent, salicylate-depende...

We explored metabolomic changes during the beneficial, growth-promoting effects of cultivating the Anabaena-azollae symbiosis, a sustainable nitrogen source for rice cultivation.

Co-Cultivation with Azolla Affects the Metabolome of Whole Rice Plant Beyond Canonical Inorganic Nitrogen Fertilization - Rice Azolla spp. are floating ferns used for centuries as biofertilizers to enrich the soil with inorganic nitrogen and improve rice yields. However, the molecular interactions between Azolla and co-cultiv...

Excited to share our latest publication originating from an Erasmus+ project with the University of Perugia and CNR! thericejournal.springeropen.com/articles/10....

Drought-induced plant microbiome and metabolic enrichments improve drought resistance

A new metabolomic strategy using mass spectrometry and stable-isotope tracing to uncover unknown metabolic reactions.

This is figure 3, which provides a synthetic diagram showing a summary of the results, including individual physiology (hydraulics and growth) and forest carbon dynamics.

Drought is a growing issue in tropical rainforests. A study in Nature Ecology & Evolution revisits a long-term rainfall manipulation experiment in the Amazon to show that tree mortality was followed by community-level adjustments to reduced precipitation. go.nature.com/4kbQbfu 🧪

Rice JA oxidases control JA-Ile levels to balance growth and defense. Loss of JAO boosts blast resistance but reduces early growth and yield, by diverting metabolic flux upstream of JA-Ile formation. #Phytohormons @plantphys.bsky.social

Very nice review!! Thank you Matt!

This is figure 1, which shows the clustering of human microbiome metabolites based on related biosynthetic pathways and phylum origins.

The human microbiota produces peptide and non-peptide secondary metabolites that have antibacterial properties vital to medicine and biotechnology. A Review in npj Biofilms and Microbiomes explores their structures and functions. go.nature.com/4kh26so #medsky 🧪

Happy to see that my partners on this exciting @dfg.de project G:(GEPRIS)516726624 are now on Bluesky: @ag-bonkowski.bsky.social and @gilloro.bsky.social

The meeting will take place on the 9th and 10th of October! #metabolomics #lipidomics Join us!

Thank you @volt.bsky.social and @rikkarinnan.bsky.social for organizing the 1rst symposium on VOCs and interaction in Copenhagen. It was a great opportunity to present our findings on #VOC emissions of #Petrichor from the #Negevdesert. @ag-bonkowsky.bsky.social @jpschnitzlerlab.bsky.social

I am excited to start our field campaign to study the interaction between herbivory, leaf phytochemicals and microbiome under a simulated drought forest experiment at KROOF 🌿🦋🔬 @plantmicrobiosis.bsky.social #Grams #MichaelEisenring #MartinGossner #WLS #TUM

The first day of sampling is finally over, and it has been a success! Hundreds of insects have been collected, can't wait to understand the interplay with tree chemodiversity! Exciting times ahead and fun below the canopy! 🦋🌿🔬 #insectdiversity #phytochemicaldiversity #microbialdiversity

Finger-crossed!

Integration of fungal transcriptomics and metabolomics provides insights into the early interaction between the ORM fungus Tulasnella sp. and the orchid Serapias vomeracea seeds - IMA Fungus In nature, germination of orchid seeds and early plant development rely on a symbiotic association with orchid mycorrhizal (ORM) fungi. These fungi provide the host with the necessary nutrients and fa...
