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. 💫

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.

🚨 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/10.110…

@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.
