--- res: bibo_abstract: - Size control is a fundamental question in biology, showing incremental complexity in plants, whose cells possess a rigid cell wall. The phytohormone auxin is a vital growth regulator with central importance for differential growth control. Our results indicate that auxin-reliant growth programs affect the molecular complexity of xyloglucans, the major type of cell wall hemicellulose in eudicots. Auxin-dependent induction and repression of growth coincide with reduced and enhanced molecular complexity of xyloglucans, respectively. In agreement with a proposed function in growth control, genetic interference with xyloglucan side decorations distinctly modulates auxin-dependent differential growth rates. Our work proposes that auxin-dependent growth programs have a spatially defined effect on xyloglucan’s molecular structure, which in turn affects cell wall mechanics and specifies differential, gravitropic hypocotyl growth.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Silvia Melina foaf_name: Velasquez, Silvia Melina foaf_surname: Velasquez - foaf_Person: foaf_givenName: Xiaoyuan foaf_name: Guo, Xiaoyuan foaf_surname: Guo - foaf_Person: foaf_givenName: Marçal foaf_name: Gallemi, Marçal foaf_surname: Gallemi foaf_workInfoHomepage: http://www.librecat.org/personId=460C6802-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0003-4675-6893 - foaf_Person: foaf_givenName: Bibek foaf_name: Aryal, Bibek foaf_surname: Aryal - foaf_Person: foaf_givenName: Peter foaf_name: Venhuizen, Peter foaf_surname: Venhuizen - foaf_Person: foaf_givenName: Elke foaf_name: Barbez, Elke foaf_surname: Barbez - foaf_Person: foaf_givenName: Kai Alexander foaf_name: Dünser, Kai Alexander foaf_surname: Dünser - foaf_Person: foaf_givenName: Martin foaf_name: Darino, Martin foaf_surname: Darino - foaf_Person: foaf_givenName: Aleš foaf_name: Pӗnčík, Aleš foaf_surname: Pӗnčík - foaf_Person: foaf_givenName: Ondřej foaf_name: Novák, Ondřej foaf_surname: Novák - foaf_Person: foaf_givenName: Maria foaf_name: Kalyna, Maria foaf_surname: Kalyna - foaf_Person: foaf_givenName: Gregory foaf_name: Mouille, Gregory foaf_surname: Mouille - 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: Rishikesh P. foaf_name: Bhalerao, Rishikesh P. foaf_surname: Bhalerao - foaf_Person: foaf_givenName: Jozef foaf_name: Mravec, Jozef foaf_surname: Mravec - foaf_Person: foaf_givenName: Jürgen foaf_name: Kleine-Vehn, Jürgen foaf_surname: Kleine-Vehn bibo_doi: 10.3390/ijms22179222 bibo_issue: '17' bibo_volume: 22 dct_date: 2021^xs_gYear dct_identifier: - UT:000694347100001 dct_isPartOf: - http://id.crossref.org/issn/1661-6596 - http://id.crossref.org/issn/1422-0067 dct_language: eng dct_publisher: MDPI@ dct_subject: - auxin - growth - cell wall - xyloglucans - hypocotyls - gravitropism dct_title: Xyloglucan remodeling defines auxin-dependent differential tissue expansion in plants@ fabio_hasPubmedId: '34502129' ...
