Check out the first article I wrote for Plantae about...writing 👇. What an incredible impact researching for this topic had on me! Thanks a lot @PoletCarrillo1 and @PetrasekLab for letting me interview you and sharing your experiences.

#EESPlantDiversity What an amazing event at EMBL (Heidelberg), with lots of genomics and metabolomics in addressing plant diversity. I'm glad I could provide some insights from streptophyte algae.

Our latest now typeset @biochechu @aadavilla @MarhavaPetra @PetrasekLab: • PAX stimulates PIN-mediated auxin efflux but also PIN endocytosis > PIN activation and turnover may be linked • auxin efflux manipulation shifts timing of cellular differentiation track.smtpsendmail.com/90321…

A collaborative effort with @PetrasekLab. Although plenty of things are unclear, PIN transporters at ER seem to bring IAA towards the auxin decarboxylation metabolic pathway. biorxiv.org/content/10.1101/…
ER-located PINs generate potent auxin sinks driven by the IAA decarboxylation pathway

ER-located PINs generate potent auxin sinks driven by the IAA decarboxylation pathway

Auxin is an essential and well-investigated regulator of plant development. Though, many aspects determining its (sub-)cellular distribution, as well as its metabolic turnover, are obscure. PIN5 is a...
