On the train back after a very inspiring workshop on root exudation in Berlin, funded by @newphyt.bsky.social

What is it, is it important, where should we be in 10 years time, and how do we get there? Stay tuned for the answers!

📢New Paper - Smart roots! Plants modify roots to maintain strategically use water. When soils are drying, plants can decrease water use from topsoil whilst boosting uptake at greater depths. 🌱💧

Mature beech trees redistribute soil water, equal to ca. 10% of stand #transpiration, from deeper moist #soils to dry surface soils, where seedlings of different #tree species take it up. New #hydraulicredistribution paper with TUM & BoKu Ecophys groups: doi.org/10.1111/plb....

Redistribution of soil water by mature trees towards dry surface soils and uptake by seedlings in a temperate forest

Mature beech trees redistributed soil water, equal to ca. 10% of stand transpiration, from deeper moist soils to dry surface soils, where it was taken up by seedlings of different tree species.

#Exudates decrease strongly during #plantdevelopment and #metabolome shifts from diverse, sugar-dominated to secondary exudates. Fast-growth genotypes exude root establishing, slow-growth more defensive compounds. See our paper with @drmicrowill.bsky.social and the Bauerle lab.
