Soil phosphate availability drives shifts between arbuscular mycorrhizal and ectomycorrhizal fungi in the dual mycorrhizal plant Quercus serrata Dual mycorrhizal plants are associated with both arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) fungi that differ in cost and effectiveness for nutrient acquisition. Little is known about env.....

Very proud to see our PhD student, Elsa Hilaire, receive the prize for best oral presentation at #esm2025. Congratulations Elsa!!!

Congratulations Elsa!!!

Fresh new abstract books are waiting for the #esm2025 congress, which starts in a few days. Don’t forget to follow us from Sunday onwards!

Drought mitigation in plants through root exudate-mediated rhizosphere interactions: Opportunities for future research - ScienceDirect •The study showed the role of root exudate in drought stress mitigation. •In drought conditions, increased naringenin and daidzein in exudates to attract diazotrophic bacteria. •Proteoid roots enhance surface area, carboxylic acid release, and phosphorus uptake in drought conditions. •The HvAACT1 gene aids citrate exudation at root apex, boosting elongation of root in drought conditions. •This study is useful in formulating strategies for sustainable environment management.

Drought mitigation in plants through root exudate-mediated rhizosphere interactions: Opportunities for future research - ScienceDirect

Check out this amazing special issue. The editorial from Joe Heitman nicely sets the scene and there are some spectacular reviews from many mycologists. I am glad to have been part of this, including in the 'MyShroom' section! #Fungi

A trait spectrum linking nitrogen acquisition and carbon use of ectomycorrhizal fungi Trait spectra have been used in various branches of ecology to explain and predict patterns of species distributions. Several categorical and continuous traits have been proposed as relevant for ecto...

Should we move beyond categorical traits in ectomycorrhizal fungal ecology? Fifth and final publication from my PhD is just out in @newphyt.bsky.social:

Drought-induced plant microbiome and metabolic enrichments improve drought resistance Li et al. show that drought stress promotes specific microbial and metabolite enrichments in the wheat rhizosphere. These changes enhance plant drought resistance via plant-microbes interactions and h...

The Swiss Federal Institute for Forest, Snow and Landscape Research WSL is part of the ETH Domain. Approximately 600 people work on the sustainable use and protection of the environment and on the handling of natural hazards. The Research Unit Biodiversity and Conservation Biology studies the diversity of life, from genetic diversity to species and habitat diversity, as well as their interactions. Starting May 1, 2025, or by agreement the research group Ecological Genetics offers a four-month position for a Technical assistant in soil ecology 80-100% (f/m/d) You will participate in a research project on soil biodiversity in forest sites of the Swiss National Forest Inventory. You will carry out laboratory work (measurements of abiotic soil properties) and organize and archive soil samples. You will collect, document and manage data and metadata of soil chemical and soil biological parameters and help with processing of amplicon sequencing data. You have a Bachelor's or Master's degree in biology, environmental, natural or soil sciences with a focus on microbiology and/or ecology. You have experience with general biological and biogeochemical laboratory procedures. You are comfortable with curating and managing datasets and samples. Experience with bioinformatic analysis of next-generation sequencing data is a plus. You have good communication and organisational skills and are fluent in German and English, which will help you to communicate in an international team of scientists and technicians. Working independently, flexibly and accurately is a strength, as is working in a team.
