Ancient symbiosis between plants and fungi: important insights for sustainable agriculture Low potassium and high nitrogen levels throw soils out of balance

A team led by ecologist @christinakaiser.bsky.social has discovered that mycorrhizal symbiosis is sensitive to imbalances of certain nutrients in the soil. The data come from an experiment that has been running for over 70 years.

This reveals a previously hidden layer of regulation in tree–fungus mutualism. And it opens the door to functional studies on a whole new set of candidate SSPs.

How do they work? Not by making more lateral roots. Instead, they inhibit root growth — likely redirecting development toward ectomycorrhizal root organogenesis. 8/

Problem: SSPs are tiny and wildly divergent. Automated annotation misses most of them. So we combined de novo prediction with motif-based searches to hunt them down in poplar and oak genomes. 3/

It feels like it's still winter, doesn't it? To trees, it is not. Tree dormancy is not caused by weather but by internal chemical signals which protect trees from cold. Now, most trees are ready to grow as soon as it warms a bit. This photo shows the tremendous flow of sap. Read more at Our Trees.
