Mature #oak acts as hidden irrigation system for the understory: #hydraulicredistribution of deep soil water can cover about one third of oak seedlings’ daily #transpiration. This benefit extends not only to oak regeneration but also to co-occurring shallow-rooted species. doi.org/10.3389/ffgc...

Frontiers | Shallow rooted understory plants use hydraulically redistributed water by mature oak trees during drought
Hydraulic redistribution (HR) by deep-rooting trees can provide water from deeper soil layers to shallow-rooted understory plants, yet species-specific and t...

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. 🌱💧 @newphyt.bsky.social @uonresearch.bsky.social Full story 👇 www.rothamsted.ac.uk/news/smart-r...

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....

#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.
