Scientists Discover Plant Metabolite Reprograms UVR8 Light Sensor

Michigan State University researchers found that naringenin chalcone activates UVR8 without UV‑B. The flavonoid intermediate binds the receptor, inducing a conformational shift. Read more: getnews.me/scientists-discover-plan... #uvr8 #flavonoid

Flavonoid Intermediate Reprograms Plant UV Sensor to Tolerate Sun Stress

Naringenin chalcone activates the UV‑B sensor UVR8 in Arabidopsis mutants, causing monomerization without UV‑B. The finding is reported in Nature Communications. Read more: getnews.me/flavonoid-intermediate-r... #naringeninchalcone #uvr8

Conservation and divergence of UVR8-COP1/SPA-HY5 signaling in UV-B responses of Marchantia polymorpha Ultraviolet-B radiation (UV-B) poses a major challenge to all forms of plant life. The liverwort Marchantia polymorpha (Marchantia) serves as a key model organism to study signaling pathways and to in...

Happy to share this work we did together with @yuankeliang.bsky.social in @romanulm.bsky.social lab. We looked in detail at UVR8-mediated UV-B signaling in Marchantia and found some conserved functions but also a few surprises! #plantscience #marchantia #UVR8
