Inhibition of Cell Expansion by Rapid ABP1-Mediated Auxin Effect on Microtubules? A Critical Comment.
How do cortical microtubules shape plant cells? This has been an important question ever since the microtubular cytoskeleton was found to orientate the deposition of cellulose microfibrils in the primary cell wall and control long-term anisotropic cell expansion under isotropic turgor pressure (Green, 1962). In axial plant organs, longitudinal microtubule/microfibril arrays hamper expansion in ...
متن کاملAuxin-dependent cell expansion mediated by overexpressed auxin-binding protein 1.
To test the hypothesis that auxin-binding protein 1 (ABP1) is a receptor controlling auxin-mediated plant cell expansion, ABP1 complementary DNAs were expressed in a controllable fashion in tobacco plants and constitutively in maize cell lines. Induction of Arabidopsis ABP1 expression in tobacco leaf strips resulted in an increased capacity for auxin-mediated cell expansion, whereas induction o...
متن کاملRapid auxin-induced cell expansion and gene expression: a four-decade-old question revisited.
The classical effect of the plant hormone auxin is very rapid stimulation of cell expansion followed by sustained growth over a longer time period. However, auxins are also important in other responses, such as cell division and differentiation. Recently, the TRANSPORT INHIBITOR RESPONSE1/AUXIN-BINDING F-BOX PROTEIN (TIR1/AFB) family of auxin receptors regulating the expression of auxin-induced...
متن کاملThe Role of Auxin in Cell Wall Expansion.
Plant cells are surrounded by cell walls, which are dynamic structures displaying a strictly regulated balance between rigidity and flexibility. Walls are fairly rigid to provide support and protection, but also extensible, to allow cell growth, which is triggered by a high intracellular turgor pressure. Wall properties regulate the differential growth of the cell, resulting in a diversity of c...
متن کامل-Mediated Auxin Response
The SCF TIR1 complex is a central regulator of the auxin response pathway in Arabidopsis. This complex functions as a ubiquitin protein ligase that targets members of the auxin/indoleacetic acid (Aux/IAA) family of transcriptional regulators for ubiquitin-mediated degradation in response to auxin. In an attempt to identify additional factors required for SCF TIR1 activity, we conducted a geneti...
