Interested in root phenotyping in soil and in the dark? and in Copenhagen on Oct 2? @katarzynaretzer.bsky.social will give a seminar at @ucph.bsky.social PLEN at 11.00 in room M117 - stop by and see high-resolution imaging and multi-omics at work!

Hot off the press!! At my exchange at @niab-uk.bsky.social, we found some interesting patterns in how root hairless wheat will use its microbiome (bacteria + fungi) to improve its phosphorus uptake.
The results in one sentence: bacteria may be cool, but AMF are the superstar!

Of The Oak - an immersive video installation celebrating the oak tree as a network of relationships.

The artwork invites viewers on a sensory journey across seasons, unveiling the oak's hidden vibrancy.

Currently showing at the Royal Botanic Gardens, Kew.

A large video screen set between trees in full leaf, showing an animation of the oak tree biome. A woman stands to the side, around 1/3 the height of the screen.

One of the key aspects influencing morphogenesis is mechanics. We mapped the mechanical properties of living roots at the tissue and cellular levels using Brillouin microscopy and molecular rotors.
