Three man and one women wearing blue labcoats are standing in front of aspen trees in a greenhouse. They are all smiling into the camera.

🧪🌾NEWS - Aspen controls bud formation using light and temperature

Ove Nilsson's group has now discovered how aspen trees decide between growth and winter dormancy during summer cold snaps and autumn.🌿

Curious how aspen does this? Read more here:

🧪🌾Are you at #ICAR2025 and interested in cell-to-cell communication?

Listen to our group leader @pmarhavy.bsky.social this afternoon! He will talk about how H+ drives ultra-fast root-to-root responses to wounding.

Take also a look here for more info about his research: www.upsc.se/researchers/...

TIR1-produced cAMP as a second messenger in transcriptional auxin signalling - Nature cAMP produced by the TIR1/AFB receptors of the main endogenous developmental plant hormone auxin acts as a true second messenger, revising the established paradigm of transcriptional auxin signalling.

Wow, cAMP production appears to be the key for activating canonical auxin signalling, not AUX/IAA degradation!

Also annoying - I need to revise quite a many teaching slides to update auxin signalling 😀
