Cyclophilin A is a conserved peptidyl-prolyl cis-trans isomerase (PPIase) best known as the cellular receptor of the immunosuppressant cyclosporine A. Despite significant effort, evidence of developmental functions of cyclophilin A in non-plant systems has remained obscure. Mutations in a tomato (Solanum lycopersicum) cyclophilin A ortholog, DIAGEOTROPICA (DGT), have been shown to abolish the...

Expression of TWISTED DWARF1 lacking its in-plane membrane anchor leads to increased cell elongation and hypermorphic growth

Bailly, Aurélien ; Wang, Bangjun ; Zwiewka, Marta ; Pollmann, Stephan ; Schenck, Daniel ; Lüthen, Hartwig ; Schulz, Alexander ; Friml, Jiri ; Geisler, Markus

In: The Plant Journal, 2014, vol. 77, no. 1, p. 108–118

Plant growth is achieved predominantly by cellular elongation, which is thought to be controlled on several levels by apoplastic auxin. Auxin export into the apoplast is achieved by plasma membrane efflux catalysts of the PIN-FORMED (PIN) and ATP-binding cassette protein subfamily B/phosphor-glycoprotein (ABCB/PGP) classes; the latter were shown to depend on interaction with the FKBP42, TWISTED...

export of salicylic acid from the chloroplast requires the multidrug and toxin extrusion-Like transporter EDS5

Serrano, Mario ; Wang, Bangjun ; Aryal, Bibek ; Garcion, Christophe ; Abou-Mansour, Eliane ; Heck, Silvia ; Geisler, Markus ; Mauch, Felix ; Nawrath, Christiane ; Métraux, Jean-Pierre

In: Plant Physiology, 2013, vol. 162, no. 4, p. 1815–1821

Salicylic acid (SA) is central for the defense of plants to pathogens and abiotic stress. SA is synthesized in chloroplasts from chorismic acid by an isochorismate synthase (ICS1); SA biosynthesis is negatively regulated by autoinhibitory feedback at ICS1. Genetic studies indicated that the multidrug and toxin extrusion transporter ENHANCED DISEASE SUSCEPTIBILITY5 (EDS5) of Arabidopsis...

Auxin transport during root gravitropism: transporters and techniques

Geisler, Markus ; Wang, Bangjun ; Zhu, Jinsheng

In: Plant Biology, 2014, vol. 16, no. S1, p. 50-57

Root gravitropism is a complex, plant-specific process allowing roots to grow downward into the soil. Polar auxin transport and redistribution are essential for root gravitropism. Here we summarise our current understanding of underlying molecular mechanisms and involved transporters that establish, maintain and redirect intercellular auxin gradients as the driving force for root gravitropism. We...

Arabidopsis TWISTED DWARF1 functionally interacts with auxin exporter ABCB1 on the root plasma membrane

Wang, Bangjun ; Bailly, Aurélien ; Zwiewka, Marta ; Henrichs, Sina ; Azzarello, Elisa ; Mancuso, Stefano ; Maeshima, Masayoshi ; Friml, Jiří ; Schulz, Alexander ; Geisler, Markus

In: The Plant Cell, 2013, vol. 25, no. 1, p. 202-214

Plant architecture is influenced by the polar, cell-to-cell transport of auxin that is primarily provided and regulated by plasma membrane efflux catalysts of the PIN-FORMED and B family of ABC transporter (ABCB) classes. The latter were shown to require the functionality of the FK506 binding protein42 TWISTED DWARF1 (TWD1), although underlying mechanisms are unclear. By genetic manipulation of...

ER-localized auxin transporter PIN8 regulates auxin homeostasis and male gametophyte development in Arabidopsis

Ding, Zhaojun ; Wang, Bangjun ; Moreno, Ignacio ; Dupláková, Nikoleta ; Simon, Sibu ; Carraro, Nicola ; Reemmer, Jesica ; Pěnčík, Aleš ; Chen, Xu ; Tejos, Ricardo ; Skůpa, Petr ; Pollmann, Stephan ; Mravec, Jozef ; Petrášek, Jan ; Zažímalová, Eva ; Honys, David ; Rolčík, Jakub ; Murphy, Angus ; Orellana, Ariel ; Geisler, Markus ; Friml, Jiří

In: Nature Communications, 2012, p. -

Auxin is a key coordinative signal required for many aspects of plant development and its levels are controlled by auxin metabolism and intercellular auxin transport. Here we find that a member of PIN auxin transporter family, PIN8 is expressed in male gametophyte of Arabidopsis thaliana and has a crucial role in pollen development and functionality. Ectopic expression in sporophytic tissues...

Regulation of ABCB1/PGP1-catalysed auxin transport by linker phosphorylation

Henrichs, Sina ; Wang, Bangjun ; Fukao, Yoichiro ; Zhu, Jinsheng ; Charrier, Laurence ; Bailly, Aurélien ; Oehring, Sophie C ; Linnert, Miriam ; Weiwad, Matthias ; Endler, Anne ; Nanni, Paolo ; Pollmann, Stephan ; Mancuso, Stefano ; Schulz, Alexander ; Geisler, Markus

In: The EMBO Journal, 2012, p. -

Polar transport of the plant hormone auxin is controlled by PIN- and ABCB/PGP-efflux catalysts. PIN polarity is regulated by the AGC protein kinase, PINOID (PID), while ABCB activity was shown to be dependent on interaction with the FKBP42, TWISTED DWARF1 (TWD1). Using co-immunoprecipitation (co-IP) and shotgun LC–MS/MS analysis, we identified PID as a valid partner in the interaction with...

A novel putative auxin carrier family regulates intracellular auxin homeostasis in plants

Barbez, Elke ; Kubeš, Martin ; Rolčík, Jakub ; Béziat, Chloé ; Pěnčík, Aleš ; Wang, Bangjun ; Rosquete, Michel Ruiz ; Zhu, Jinsheng ; Dobrev, Petre I. ; Lee, Yuree ; Zažímalovà, Eva ; Petrášek, Jan ; Geisler, Markus ; Friml, Jiří ; Kleine-Vehn, Jürgen

In: Nature, 2012, p. -

The phytohormone auxin acts as a prominent signal, providing, by its local accumulation or depletion in selected cells, a spatial and temporal reference for changes in the developmental program. The distribution of auxin depends on both auxin metabolism (biosynthesis, conjugation and degradation) and cellular auxin transport. We identified in silico a novel putative auxin transport facilitator...
