--- res: bibo_abstract: - The directional transport of the plant hormone auxin is a unique process mediating a wide variety of developmental processes. Auxin movement between cells depends on AUX1/LAX, PGP and PIN protein families that mediate auxin transport across the plasma membrane. The directionality of auxin flow within tissues is largely determined by polar, subcellular localization of PIN auxin efflux carriers. PIN proteins undergo rapid subcellular dynamics that is important for the process of auxin transport and its directionality. Furthermore, various environmental and endogenous signals can modulate trafficking and polarity of PIN proteins and by this mechanism change auxin distribution. Thus, the subcellular dynamics of auxin transport proteins represents an important interface between cellular processes and development of the whole plant. This review summarizes our recent contributions to the field of PIN trafficking and auxin transport regulation. © 2009 Elsevier GmbH.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Jirí foaf_name: Jirí Friml foaf_surname: Friml foaf_workInfoHomepage: http://www.librecat.org/personId=4159519E-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-8302-7596 bibo_doi: 10.1016/j.ejcb.2009.11.003 bibo_issue: 2-3 bibo_volume: 89 dct_date: 2010^xs_gYear dct_publisher: Elsevier@ dct_title: Subcellular trafficking of PIN auxin efflux carriers in auxin transport@ ...
