Polarity of Auxin Movement by Basipetal Transport'
Sikmninarv. The polar, basipetal transport of indoleacetic acid helps to mlainitain l)olarity of auxin movement in coleoptiles of Azcna sativa L. by opposing acropetal diffusion. This conclusion is supported by 3 different kinds of experiments. In all 3 experiments, sections took up 14C carboxyl-labeled indole-3-acetic acid anaerobically, anid the distribution of auxin within all sections was s...
متن کاملPolar Auxin Transport: Cell Polarity to Patterning
Auxin is a signaling molecule with profound influence on plant morphogenesis. Because of its activity gradient-related effects on plant development and response programs, it is considered as a plant morphogen. Auxin displays a spectacular ability to mobilize in a cell-to-cell and polar fashion. Auxin efflux carrier PIN proteins direct this intercellular flow of auxin and thus bear a ratelimitin...
متن کاملPolar Transport of Auxin and Electrical Polarity in Coleoptile of Avena.
In the introduction to a recent paper by the writer (5), -the phenomenon of the polar transport of auxin in plants was briefly discussed. It was indicated there that the electrical theory of the polar transport of auxin was one of the most widely accepted ones. This theory states that the inherent electrical polarity of plants is the cause of the longitudinal polar transport of the negative ion...
متن کاملCell polarity signaling: focus on polar auxin transport.
Polar auxin transport, which is required for the formation of auxin gradients and directional auxin flows that are critical for plant pattern formation, morphogenesis, and directional growth response to vectorial cues, is mediated by polarized sub-cellular distribution of PIN-FORMED Proteins (PINs, auxin efflux carriers), AUX1/AUX1-like proteins (auxin influx facilitators), and multidrug resist...
متن کاملArabidopsis 14-3-3 epsilon members contribute to polarity of PIN auxin carrier and auxin transport-related development
Eukaryotic 14-3-3 proteins have been implicated in the regulation of diverse biological processes by phosphorylation-dependent protein-protein interactions. The Arabidopsis genome encodes two groups of 14-3-3s, one of which - epsilon - is thought to fulfill conserved cellular functions. Here, we assessed the in vivo role of the ancestral 14-3-3 epsilon group members. Their simultaneous and cond...
