Huge thanks to all collaborators! Special thanks to Prof. Hidehiro Fukaki (Kobe Univ.) — his lab's imaging setup was essential. And to Dr. Takaaki Yonekura @monera-kingdom.bsky.social, a former senior whose modeling directly supported our conclusions.

This means:
💡 Cytokinin is not just a generic growth signal —
It’s a switch that creates stem cells specifically for radial growth.

So what does cytokinin actually do during this peak?
It induces and activates stem cells.
Before the CRM, cells can’t directly differentiate to xylem or self-renew. After the CRM, they gain both abilities.

In Arabidopsis roots, cytokinin response imaging revealed something surprising:
A clear but transient peak of cytokinin signaling — which we called the cytokinin response maximum (CRM) — appears.
2–3 days later, radial growth begins.

Using a vascular cell induction system called VISUAL, combined with single-cell transcriptomics and luminescence imaging, we found something else:
Cytokinin doesn't just boost division — it promotes the transition of dormant procambial cells into active cambial stem cells.

Cytokinin was already known to be important for radial growth, but mostly thought to just promote cell division.
We questioned this assumption.

In many plants like trees, bifacial cambial stem cells drive radial growth by dividing actively.
Before that, they exist as inactive procambial cells — waiting in a dormant state.

What triggers plants to start growing thicker (radial growth)?
We discovered that a transient cytokinin response maximum acts as a switch to initiate this process in roots.
So proud to share the work I started as an undergrad, now in Nature Plants! 🧵👇

A cytokinin response maximum induces and activates bifacial stem cells for radial growth - Nature Plants
This study details how plants initiate radial growth, during which a transient cytokinin response maximum transforms dormant procambial cells into bifacial stem cells, offering a basis for post-embryo...

We held a closed meeting in Atami, enjoyed the wonderful hot springs, and had a great time. I enjoyed discussing many studies and also talking about my recent theoretical work.
