TL;DR: Conditional gain-of-function alleles and quantitative measurements of auxin accumulation revealed that the action of PINs in auxin efflux is distinct from PGP, rate-limiting, specific to auxins, and sensitive to auxin transport inhibitors, which suggests a direct involvement ofPINs in catalyzing cellular auxIn efflux.
Journal ArticleDOI
EIR1, a root-specific protein involved in auxin transport, is required for gravitropism in Arabidopsis thaliana.
TL;DR: Data suggest that the EIR1 protein has a root-specific role in the transport of auxin, which is consistent with the phenotypes of the eir1 mutants of Arabidopsis and expresses only in the root.
Journal ArticleDOI
Antagonistic Regulation of PIN Phosphorylation by PP2A and PINOID Directs Auxin Flux
Marta Michniewicz,Marcelo Kennel Zago,Lindy Abas,Dolf Weijers,Alois Schweighofer,Irute Meskiene,Marcus G. Heisler,Carolyn Ohno,Jing Zhang,Fang Huang,Rebecca Schwab,Detlef Weigel,Elliot M. Meyerowitz,Christian Luschnig,Remko Offringa,Jiří Friml,Jiří Friml +16 more
TL;DR: PP2A phosphatase is identified as an important regulator of PIN apical-basal targeting and auxin distribution and switches in the direction of intercellular auxin fluxes, which mediate differential growth, tissue patterning, and organogenesis in plants.
Journal ArticleDOI
Functional redundancy of PIN proteins is accompanied by auxin-dependent cross-regulation of PIN expression
Anne Vieten,Steffen Vanneste,Justyna Wiśniewska,Eva Benková,René Benjamins,Tom Beeckman,Christian Luschnig,Jiri Friml +7 more
TL;DR: It is shown that PIN proteins exhibit synergistic interactions, which involve cross-regulation of PIN gene expression in pin mutants or plants with inhibited auxin transport, which might enable the stabilization of auxin gradients and potentially contribute to the robustness of plant adaptive development.
Journal ArticleDOI
Intracellular trafficking and proteolysis of the Arabidopsis auxin-efflux facilitator PIN2 are involved in root gravitropism
Lindy Abas,René Benjamins,Nenad Malenica,Tomasz Paciorek,Justyna Wiśniewska,Jeanette Moulinier-Anzola,Tobias Sieberer,Jiří Friml,Jiří Friml,Christian Luschnig +9 more
TL;DR: It is shown that intracellular trafficking and proteasome activity combine to control PIN2 degradation during root gravitropism, indicating that redistribution of auxin during the Gravitropic response may be involved in the regulation of PIN2 protein.
