Figure with six panels showing where and how Arabidopsis plants shed their organs. (A) A flower with zones where petals, sepals, and stamens will detach. (B) A leaf with a marked separation point. (C) A tiny zone where seeds detach. (D) A close-up view of the flower’s base, highlighting key abscission sites. (E) A detailed look at the cells involved in petal and stamen detachment. (F) How the plant’s structure appears after floral parts fall off. (G) A special reinforcement in sepals, stained to reveal lignin, a key structural component.

Abscission zones form at predictable spots in plants. When activated, they trigger structural and physiological changes that detach the organ and seal the exposed area. 🍂🌸🍅 (3/7)

🚨 PhD Opportunity Alert! 🚨 I'm thrilled to announce my new project, Watchers on the Wall, exploring how plant cells sense and respond to stress through their walls. 🌱 A 5-year fully funded PhD position is open—please share with potential candidates! 👇 (1/7)

FERONIA adjusts CC1 phosphorylation to control microtubule array behavior in response to salt stress A receptor-like kinase controls cell wall biosynthesis under salt stress by regulating microtubule organization.

In case you're not already saturated with #FERONIA papers, here's one more linking FER to #PlantCellWalls integrity sensing during #SaltStress.

Co-first-authored by Liu Wang, who did the work for her PhD with me ☺️

This is so useful and probably one of the best ways to get this network to liven up even more!

Thanks a lot @somssich.bsky.social!!

I have updated the #PlantScience #StarterPack. You can now include 150 accounts, instead of the initial 50.
I have tried to focus on active accounts.

To supplement this great #PlantScience #StarterPack of active individuals, I made a starter pack of journals, departments, institutes, and professional societies related to plant science. go.bsky.app/Q9QiX9C

There is also a second #PlantScience / #Botany #StarterPack put together by @botany.one:

Many thanks to all our collaborators! 🙌🏻 And also to @currentbiology.bsky.social for the speedy handling of our manuscript!

A multifaceted kinase axis regulates plant organ abscission through conserved signaling mechanisms Galindo-Trigo et al. show that BSK1 and BSK2 regulate floral organ abscission in Arabidopsis. BSK1 localizes to the plasma membrane and interacts with HAE/HSL2. A hypermorphic allele of BSK1 activates...

Excited to see my latest project finally published! 🎉

We identified BSK proteins as regulators of IDA signaling and abscission 🍃. Our genetic work also points at a generalized mode of action for BSK1 across RLK pathways (HAE, FLS2, ERECTA, BRI1).
