Some news: I’m joining Umeå Plant Science Centre at Umeå University next month as a group leader!

Expanding the mycorrhizal adventures to new systems, forests, collaborations & opportunities. I’ll recruit students & postdocs soon

Very much still part of the HIE! with my research continuing there

Boreal forest soils are major carbon reservoirs. But how does soil biodiversity shape the fate of this carbon?

Thanks to the Finnish Cultural Foundation, @sanslan.bsky.social and I will untangle how soil fauna–fungi interactions influence carbon pools in Finland.

We’ve posted a new preprint providing evidence that endophytic fungi facilitate resource transfer through common mycelial networks. A neat aspect of our study is that we measured fungal functional changes when connected to more than one plant, not just the plants!

Mutualist-pathogen co-colonisation modulates phosphoinositide signatures at host intracellular interfaces: Nicotiana benthamiana plants expressing biosensors for PI4P and PI(4,5)P2. PI(4,5)P2 was tip-enriched at mutualist structures but evenly distributed around pathogen structures. PI4P was absent from pathogen extrahaustorial membranes but present at invasive hyphae and mutualist interfaces. Co-colonisation triggered PI4P recruitment at pathogen haustoria, and enhanced resistance to P. palmivora. Graphic by Alex Guyon.

Not Extremely Plastic: Testing the Limits of Morphological Plasticity in Fungal Mycelia in Response to Soil Grazers Using image analysis to track the development of fungal networks in the presence of predators, we found that even in modular organisms, plasticity is more nuanced and limited than previously assumed....

Turns out fungi aren’t as plastic as we might think, their responses to grazers are much more species-specific.

What Everyone Should Know About Fungi by Age 15

2️⃣ > 400 million years ago, mycorrhizal fungi enabled plants to transition from aquatic to terrestrial environments, making life on land possible.

See the top 10 list (buff.ly/77S4PQF ) and follow for new fungal facts.

Fig. 7 (shortened, full legend in paper): Intraspecific variation in key root functional traits involved in P acquisition between low-phosphorus efficiency (LPE) and high-phosphorus efficiency (HPE) genotypes of alfalfa in response to low soil phosphorus (P) availability. The blue upward arrow indicates P uptake from low P soil, while the black downward arrow signifies carbon (C) transport into root functional traits associated with P acquisition. The mean values for each trait are shown. If there are significant differences between LEP and HEP genotypes, the higher values are emphasized in bold and marked with asterisks: *P≤0.05, ***P≤0.001.

Alfalfa genotypes with thick roots, increased exudate concentration, and mycorrhizal colonization under low P environments have high P utilization efficiency, opening up the potential for breeding for P-efficient lines - Fan et al.
