• Field: Genetics and molecular biology
• Keywords: auxin transport; subcellular compartmentalisaiton; PIN localisation; evolution
• Description: Here we propose an eventually ancient mechanism of intercellular auxin distribution by ER-localized auxin transporters involving intracellular auxin retention and switch-like release from the ER. Computer simulations of the model revealed its plausibility for generating localized auxin maxima.
