An auxin homeostat allows plant cells to establish and control defined transmembrane auxin gradients

The paper uses mathematical modeling to show how auxin transporters work together to create and control transmembrane auxin gradients in plants.

Cytokinin synthesis and export from symbiotic root nodules coordinates shoot growth with nitrogen fixation

This study identifies LjPup1 as a cytokinin exporter in root nodules that coordinates shoot growth with nitrogen fixation by exporting active cytokinins.

Restriction of access to the central cavity is a major contributor to substrate selectivity in plant ABCG transporters

The paper identifies a narrow access path in MtABCG46 that contributes to substrate selectivity in plant ABCG transporters.

ABA homeostasis and long-distance translocation is redundantly regulated by ABCG ABA importers

This study identifies ABCG17 and ABCG18 as ABA importers that redundantly regulate ABA homeostasis and translocation in Arabidopsis, affecting stomatal closure and root development.

ABCB-mediated auxin transport in outer root tissues regulates lateral root spacing in Arabidopsis

The paper identifies five ABCB transporters that regulate lateral root spacing in Arabidopsis by modulating auxin oscillation amplitude in outer root tissues.

A conserved D/E-P motif in the nucleotide binding domain of plant ABCB/PGP-type ABC transporters defines their auxin transport capacity

The paper identifies a conserved D/E-P motif in plant ABCB transporters that defines their auxin transport capacity and shows its role in interaction with TWD1.
