[EN] Cell expansion is an increase in cell size and thus plays an essential role in plant growth and development. Phytohormones and the primary plant cell wall play major roles in the complex process of cell expansion. In shoot tissues, cell expansion requires the auxin receptor AUXIN BINDING PROTEIN1 (ABP1), but the mechanism by which ABP1 affects expansion remains unknown. We analyzed the effect of functional inactivation of ABP1 on transcriptomic changes in dark-grown hypocotyls and investigated the consequences of gene expression on cell wall composition and cell expansion. Molecular and genetic evidence indicates that ABP1 affects the expression of a broad range of cell wall-related genes, especially cell wall remodeling genes, mainly via an SCFTIR/AFB-dependent pathway. ABP1 also functions in the modulation of hemicellulose xyloglucan structure. Furthermore, fucosidase-mediated defucosylation of xyloglucan, but not biosynthesis of nonfucosylated xyloglucan, rescued dark-grown hypocotyl lengthening of ABP1 knockdown seedlings. In muro remodeling of xyloglucan side chains via an ABP1-dependent pathway appears to be of critical importance for temporal and spatial control of cell expansion.

We thank Markus Pauly (University of California, Berkeley) for kindly providing the seeds of AXY8 overexpressor, Mark Estelle (University of California, San Diego, Howard Hughes Medical Institute) for seeds of the triple tir afb2 afb3 mutant, Xing Wang Deng (Yale University) for seeds of cop10-4, Doan Luu (CNRS, Montpellier) for seeds of the 35S: PIP2; 1-GFP line, and Jiri Friml (Institute of Science and Technology, Vienna) for seeds of the abp1-5 mutant. We thank Sylvie Citerne from the Plant Observatory at Institut Jean-Pierre Bourgin (INRA) for cell wall composition analysis. This work has benefitted from the facilities and expertise of the Imagif Cell Biology Unit of the Gif campus, which is supported by the Conseil General de l'Essonne, France. We also thank Jessica Marion for technical assistance in electron microscopy. This work was supported by the ANR blanc AuxiWall Project ANR-11-BSV5-0007. C.P.-R.'s team is also funded by the CNRS and G.M. by INRA. Work in the laboratories of D.A. and M.A.B. was supported by grants from the Spanish Ministry of Science and Innovation (BIO2010-15071 and CSD2007-00057) and the Generalitat Valenciana (ACOMP/2011/288 and PROMETEO/2010/020). We thank Philip Harris (University of Auckland) and Spencer Brown (Institut des Sciences du Vegetal, CNRS) for critical reading of the article and useful comments.
