    ..Together, these results indicate a role for auxin in the orientation of developmental polarity and suggest interactions between the actin cytoskeleton and auxin transport in F. distichus embryos...
  2. Lewis D, Muday G. Measurement of auxin transport in Arabidopsis thaliana. Nat Protoc. 2009;4:437-51 pubmed publisher
    ..These methods allow investigation of genetic and environmental factors that control auxin transport...

    ..These results indicate a negative role for ethylene in lateral root formation and a positive role in adventitious root formation with modulation of auxin transport as a central point of ethylene-auxin crosstalk. ..

    ..Based on these results, a two-phase model describing possible relationships between gravitropic curvature, IAA redistribution, and Ivr2 expression is presented...

    ..Our data suggest that PID plays a limited role in root development; loss of PID activity alters auxin transport and gravitropism without causing an obvious change in cellular polarity. ..
  6. Muday G, Rahman A, Binder B. Auxin and ethylene: collaborators or competitors?. Trends Plant Sci. 2012;17:181-95 pubmed publisher
    ..The emerging trend from these experiments is that ethylene modulates auxin synthesis, transport, and signaling with unique targets and responses in a range of tissues to fine-tune seedling growth and development. ..
  7. Brown D, Rashotte A, Murphy A, Normanly J, Tague B, Peer W, et al. Flavonoids act as negative regulators of auxin transport in vivo in arabidopsis. Plant Physiol. 2001;126:524-35 pubmed
    ..These results are consistent with a role for flavonoids as endogenous regulators of auxin transport. ..
  8. Rashotte A, DeLong A, Muday G. Genetic and chemical reductions in protein phosphatase activity alter auxin transport, gravity response, and lateral root growth. Plant Cell. 2001;13:1683-97 pubmed
    ..These results support the role of protein phosphorylation in regulating auxin transport and suggest that the acropetal and basipetal auxin transport streams are differentially regulated. ..
  9. Muday G. Auxins and tropisms. J Plant Growth Regul. 2001;20:226-43 pubmed
    ..Although many details of the mechanisms by which plants respond to gravity and light are not yet clear, numerous recent studies demonstrate the role of auxin in these processes. ..

    ..The results of this study suggest that auxin acts in the formation of apical basal patterns in F. distichus embryo development. ..
  2. Buer C, Sukumar P, Muday G. Ethylene modulates flavonoid accumulation and gravitropic responses in roots of Arabidopsis. Plant Physiol. 2006;140:1384-96 pubmed
    ..Together, these experiments suggest that elevated ethylene levels negatively regulate root gravitropism, using EIN2- and ETR1-dependent pathways, and that ACC inhibition of gravity response occurs through altering flavonoid synthesis. ..

    ..These results suggest that ACC treatment increased PIN3 and PIN7 expression, resulting in elevated auxin transport, which prevented the localized accumulation of auxin needed to drive lateral root formation. ..
  5. Sukumar P, Maloney G, Muday G. Localized induction of the ATP-binding cassette B19 auxin transporter enhances adventitious root formation in Arabidopsis. Plant Physiol. 2013;162:1392-405 pubmed publisher
    ..These experiments are consistent with localized synthesis of ABCB19 protein after hypocotyl excision leads to enhanced IAA transport and local IAA accumulation driving adventitious root formation. ..
