Abstract excerpt
Asymmetric auxin distribution caused by polar auxin transport (PAT) regulates many plant developmental and physiological processes. Plant two closely ABC (ATP-binding cassette) transporter, AtPGP1 and AtPGP19 (AtMDR1), have been implicated in auxin transport. However, unlike atpgp19 mutant and atpgp1 atmdr1 double mutant show decreased apical dominance, reduced growth, and impaired basipetal auxin transport,...
