🚨 New preprint by @Cate_Giannini🚨
We uncover an unexpected link between auxin signalling, transcription, and autophagy — revealing how plants coordinate gene expression and cytoplasmic renewal to drive developmental reprogramming. 🌱✨ biorxiv.org/content/10.1101/…
In auxin maxima, autophagy lights up — and in autophagy-deficient mutants, differentiation slows down.
Auxin doesn’t just tell cells who to become — it helps them clear the decks to become something new.
Our study reveals a dual role for auxin: coordinating gene expression and cytoplasmic remodeling via autophagy — ensuring fast, efficient developmental reprogramming.
Auxin doesn’t just permit change. It enables it. 💫
For those that want to learn more about auxin, I am proud to present our latest review

Pflanzen üben auf den Biologen & Wittgenstein-Preisträger Jiřà Friml eine besondere Faszination aus. Er hat die Funktion des Hormons #Auxin als Vermittler zw. Umgebung und Zellkommunikation in #Pflanzen entdeckt. @ISTAustria🌿

@kat_kurtovic in our New Phytol: auxin has effect on regeneration in Chara braunii, at least one its PIN is PM localized with auxin-transporting activity and distribution correlated to acid bands in Chara cells. IAA application induces MAPKs within minutes

How polarized tissue repair is achieved upon excision?
Using a bryophyte Physcomitrium patens, Han Tang et al. revealed that the proper polarization of PIN-FORMED #auxin exporter is a key process🔑

ROS bursts after auxin, RALF, eATP or mechanical bending? We monitored them all. What triggers them and what are they good for? Many surprises! Read our new preprint, a second one in a row. Thanks ISTA and Biology Centre CAS for amazing environment. biorxiv.org/content/10.1101/…
Armadillo Repeat Only proteins enable function of multiple, if not all CNGC channels. These are essential for plethoha of calcium signals triggered by stresses, hormones and pathogens. Read our new perprint.
