Plant hormone and peptide signaling converge in the genetic network regulating cambium activation in Arabidopsis roots An intertwined network of cytokinin, auxin and peptide hormone signaling activates secondary growth in the Arabidopsis roots.

After a long journey, our new paper is out! 🌱
In this study, Tiina and colleagues show that cambium activation in the Arabidopsis root is triggered by the induction of auxin, cytokinin, and TDIF peptide signalling. 🧵1/x doi.org/10.1093/plce...

During secondary growth, primary protective barriers break, and a new one forms beneath: the phellem.

But what triggers phellem to differentiate and become a functional barrier? Our results show it’s mechanical cues from tissue rupture 🌱

Latest preprint from our group together with @stephanevrg.bsky.social @wabniklab.bsky.social @kleinevehnlab.bsky.social

Our work supports the view that morphogenesis is not driven by growth alone, but by the integration of physical and biological regulation.

🧪🌾News - How do trees know when winter has really begun?

New research from the Bhalerao group in @natcomms.nature.com shows that trees don’t just count cold hours - they also use brief warm spells early in winter.

🧪🌾 PAPER – How do trees know when winter is really over?

Trees don’t just track long-term cold exposure. The Bhalerao group and collaborators show they also count short warm spells when assessing winter progression.

Thrilled to have our paper out in @science.org. Cell division guides plant cell wall formation. Does the reverse hold? We show that bimodal pectin methylesterification, via PME5 mRNA nuclear sequestration, influences plant cell division and cell plate orientation. www.science.org/doi/10.1126/...
