Auxin immunolocalization implicates vesicular neurotransmitter-like mode of polar auxin transport in root apices.
Immunolocalization of auxin using a new specific antibody revealed, besides the expected diffuse cytoplasmic signal, enrichments of auxin at end-poles (cross-walls), within endosomes and within nuclei of those root apex cells which accumulate abundant F-actin at their end-poles. In Brefeldin A (BFA) treated roots, a strong auxin signal was scored within BFA-induced compartments of cells having ...

متن کاملAuxin-induced H Secretion in Helianthus and Its Implications.
We have examined the ability of Helianthus hypocotyl segments as well as segments from a variety of other species to elongate in response to H(+) and to secrete H(+) in response to auxin and fusicoccin. In all cases a positive response was obtained when the cuticular barrier was abraded with carborundum. Removal of the cuticular barrier by "peeling" prevented detection of both auxin-induced elo...
متن کاملAuxin auxin everywhere
But the discrete clocks can work as one because they are synchronized by electrical impulses. Our internal clock, which controls circadian behaviors and physiology, is a circuitry of many thousands of neurons in the brain called the suprachiasmatic nucleus (SCN). The Kobe group looked at communication within this circuitry in cultured brain slices of transgenic mice using a fluorescent reporter...
متن کاملAstrocytes as secretory cells of the central nervous system: idiosyncrasies of vesicular secretion.
Astrocytes are housekeepers of the central nervous system (CNS) and are important for CNS development, homeostasis and defence. They communicate with neurones and other glial cells through the release of signalling molecules. Astrocytes secrete a wide array of classic neurotransmitters, neuromodulators and hormones, as well as metabolic, trophic and plastic factors, all of which contribute to t...
