--- res: bibo_abstract: - The prominent and evolutionarily ancient role of the plant hormone auxin is the regulation of cell expansion. Cell expansion requires ordered arrangement of the cytoskeleton but molecular mechanisms underlying its regulation by signalling molecules including auxin are unknown. Here we show in the model plant Arabidopsis thaliana that in elongating cells exogenous application of auxin or redistribution of endogenous auxin induces very rapid microtubule re-orientation from transverse to longitudinal, coherent with the inhibition of cell expansion. This fast auxin effect requires auxin binding protein 1 (ABP1) and involves a contribution of downstream signalling components such as ROP6 GTPase, ROP-interactive protein RIC1 and the microtubule-severing protein katanin. These components are required for rapid auxin-and ABP1-mediated re-orientation of microtubules to regulate cell elongation in roots and dark-grown hypocotyls as well as asymmetric growth during gravitropic responses.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Xu foaf_name: Chen, Xu foaf_surname: Chen foaf_workInfoHomepage: http://www.librecat.org/personId=4E5ADCAA-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Laurie foaf_name: Grandont, Laurie foaf_surname: Grandont - foaf_Person: foaf_givenName: Hongjiang foaf_name: Li, Hongjiang foaf_surname: Li foaf_workInfoHomepage: http://www.librecat.org/personId=33CA54A6-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-5039-9660 - foaf_Person: foaf_givenName: Robert foaf_name: Hauschild, Robert foaf_surname: Hauschild foaf_workInfoHomepage: http://www.librecat.org/personId=4E01D6B4-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-9843-3522 - foaf_Person: foaf_givenName: Sébastien foaf_name: Paque, Sébastien foaf_surname: Paque - foaf_Person: foaf_givenName: Anas foaf_name: Abuzeineh, Anas foaf_surname: Abuzeineh - foaf_Person: foaf_givenName: Hana foaf_name: Rakusova, Hana foaf_surname: Rakusova foaf_workInfoHomepage: http://www.librecat.org/personId=4CAAA450-78D2-11EA-8E57-B40A396E08BA - foaf_Person: foaf_givenName: Eva foaf_name: Benková, Eva foaf_surname: Benková foaf_workInfoHomepage: http://www.librecat.org/personId=38F4F166-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-8510-9739 - foaf_Person: foaf_givenName: Catherine foaf_name: Perrot Rechenmann, Catherine foaf_surname: Perrot Rechenmann - foaf_Person: foaf_givenName: Jirí foaf_name: Friml, Jirí foaf_surname: Friml foaf_workInfoHomepage: http://www.librecat.org/personId=4159519E-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-8302-7596 bibo_doi: 10.1038/nature13889 bibo_issue: '729' bibo_volume: 516 dct_date: 2014^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/0028-0836 - http://id.crossref.org/issn/1476-4687 dct_language: eng dct_publisher: Nature Publishing Group@ dct_title: Inhibition of cell expansion by rapid ABP1-mediated auxin effect on microtubules@ fabio_hasPubmedId: '25409144' ...
