Last week, March 13-14th with my colleagues @PetrasekLab @UEBavcr & I participated in #ScienceisWonderful Organized by @Cecoforma1 & supported by @MSCActions @EU_Commission, we set up a dark booth for #bioluminescentplants so kids & adults could interact, learn & ask questions

Jedna z našich laboratoří, které můžete navštívit 7. 11., má novinku: DARK LAB. Umíme rozsvítit rostliny pomocí bioluminiscence. Máme pro to dobrý důvod: světélkující rostlina nám může říct, jak se cítí v různých podmínkách. Víc info a rezervace na ueb.cas.cz/cs/DOD

It looks like @MedicagoCrew is illustrating the functional diversification of the ABCGs with his hand gesture, but we've heard ;-) that he's actually clapping to acknowledge how attentive his audience is during his great speech today @UEBavcr We're happy to have him as a guest!

#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…

Ectopic assembly of an auxin efflux control machinery shifts developmental trajectories

Postmeristematic auxin increase promotes cellular differentiation in the Arabidopsis root tip.

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

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...
