Loss of GSNOR1 Function Leads to Compromised Auxin Signaling and Polar Auxin Transport.
Cross talk between phytohormones, nitric oxide (NO), and auxin has been implicated in the control of plant growth and development. Two recent reports indicate that NO promoted auxin signaling but inhibited auxin transport probably through S-nitrosylation. However, genetic evidence for the effect of S-nitrosylation on auxin physiology has been lacking. In this study, we used a genetic approach t...
متن کاملKinetics of polar auxin transport.
The movement of auxin in the basipetal and acropetal directions is compared for 4 types of tissue. It is observed that the transport may proceed in either a linear or a non-linear manner with time. The polarity of transport through any given type of tissue increases exponentially with increasing lengths of tissue traversed, suggesting that the polarity of transport is developed as a consequence...
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 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 کاملPolar auxin transport: models and mechanisms.
Spatial patterns of the hormone auxin are important drivers of plant development. The observed feedback between the active, directed transport that generates auxin patterns and the auxin distribution that influences transport orientation has rendered this a popular subject for modelling studies. Here we propose a new mathematical framework for the analysis of polar auxin transport and present a...
