Low soil phosphorus conditioning enhances mutualism in Rhizophagus irregularis regardless of nuclear organization, even when phosphorus conditions shift - Mycorrhiza
Strains of the arbuscular mycorrhizal (AM) fungus Rhizophagus irregularis belong to one of two nuclear organizations: homokaryons, which carry genetically similar nuclei, and dikaryons, which harbour ...

It has been a great experience volunteering on the IMS board. We have new student awards, a new logo, a refreshed website, and we’re set for the next ICOMs. We also have t-shirts! All to ensure that mycorrhizal research continues to thrive. Come see our booth at #icom2026 !

On my way to #icom2026. A long trip with long flights, but I feel good knowing that this conference directly contributes to the conservation of the Daintree rainforest and the Great Barrier Reef. Looking forward to it.

Very pleased to share that, as of June 1st, I'll be serving as an Editor at New Phytologist; interactions section. It’s an honour, and I'm grateful for the opportunity to contribute to a journal I've always admired, and that has played such an important role in advancing plant science.

Happy to share this work co-authored with Ylva Lekberg and Jonathan Plett. In a world plagued by war and environmental destruction, research into how mycorrhizal fungi can advance the UN sustainability goals might seem irrelevant. It is not. academic.oup.com/femsle/advan...

#Viewpoint: A critical reassessment of the novel weapons hypothesis and allelopathy as an adaptive strategy that facilitates #PlantInvasion Robert Colautti & Pedro Madeira Antunes 👇 📖 nph.onlinelibrary.wiley.com/doi/10.1111/... #LatestIssue #PlantScience
Illustration of a simple allelopathy model that considers the ith individual of an invasive species and the jth individual of a native competitor, such as the North American invasive plant Alliaria petiolata (garlic mustard), shown on the left, and the native Acer saccharum (sugar maple), on the right.

Now published in @newphyt.bsky.social, @1pantunes.bsky.social and I review evidence for the "Novel Weapons Hypothesis" and the role of allelopathy during invasion. Bottom line: there is very good reason to be skeptical. dx.doi.org/10.1111/nph....
Experimental approaches and key outcomes supporting the Allelopathy Postulates relevant to competitive interactions and the novel weapons hypothesis (NWH). Numbers in red correspond to the 11 postulates summarized in Table 1. The full experimental framework comprises five sequential steps: (a) assess the natural concentrations of a potential allelopathic compound; (b) demonstrate its ability to suppress native vegetation; releasing resources that enhance growth and reproduction of the invader (e.g. light, nutrients, water); (c) confirm that the compound has limited autotoxicity to the invading species; (d) investigate the biogeographical basis of the allelopathic compound as a ‘novel weapon’ by demonstrating that native communities coevolving with the invader in its home range are significantly more resistant to the allelopathic compound compared to those in the introduced (away) range; (e) confirm that genotypes producing higher concentrations of the allelopathic compounds experience a fitness cost in the context of intraspecific competition but gain a fitness advantage under interspecific competition. Investigating the role of soil-mediated interactions (11) is transversal across different components of the framework

Pleated inkcap (Parasola plicatilis) fruiting bodies rise, spread their spores and decay within 24 hours after a rainfall. They are very small and delicate. These middle-aged ones (7-10 hours old) were around our field today.

A data matrix summarizing eleven Allelopathy Postulates across 41 studies testing the Novel Weapons Hypothesis (NWH). Of the 451 total cells, 351 are shaded grey, indicating that most postulates were untested in most studies. Of the remaining 100, 78 are shaded green, indicating support for the NWH while the remaining 22 indicate evidence contrary to the NWH or mixed support.
