Auxin transport: providing a sense of direction during plant development.
Auxins are key regulators of plant development. Plants employ a specialized delivery system termed polar auxin transport to convey indole-3-acetic acid from source to target tissues. Auxin transport is mediated by the combined activities of specialized influx and efflux carriers. Mutational approaches in the model plant, Arabidopsis thaliana, have led to the molecular genetic characterization o...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
A cell's sense of direction.
In eukaryotic cells directional sensing is mediated by heterotrimeric guanine nucleotide-binding protein (G protein)-linked signaling pathways. In Dictyostelium discoideum amoebae and mammalian leukocytes, the receptors and G-protein subunits are uniformly distributed around the cell perimeter. Chemoattractants induce the transient appearance of binding sites for several pleckstrin homology dom...
متن کاملDirectional Auxin Transport Mechanisms in Early Diverging Land Plants
The emergence and radiation of multicellular land plants was driven by crucial innovations to their body plans. The directional transport of the phytohormone auxin represents a key, plant-specific mechanism for polarization and patterning in complex seed plants. Here, we show that already in the early diverging land plant lineage, as exemplified by the moss Physcomitrella patens, auxin transpor...
متن کاملAuxin transport: Why plants like to think BIG
The regulation of auxin transport via auxin efflux carriers likely plays a central role in a variety of physiological responses in higher plants. With the isolation of BIG, an Arabidopsis protein of enormous size, another potential regulator of auxin transport has been characterized.
