Electrophysiological responses of maize roots to low water potentials: relationship to growth and ABA accumulation.
The maintenance of root elongation is an important adaptive response to low water potentials (psi(w)), but little is known about its regulation. An important component may be changes in root cell electrophysiology, which both signal and maintain growth maintenance processes. As a first test of this hypothesis, membrane potentials (E(m)) were measured within the cell elongation zone of maize (Ze...
متن کاملMechanism of the Net Uptake of Water in Moulting Blue Crabs (callinectes Sapidus) Acclimated to High and Low Salinities
Blue crabs (Callinectes sapidus Rathbun) acclimated to a salinity of 2 approximately doubled in wet mass (excluding carapace) during the period from 10 h before moult to 2 h after moult. Both in blue crabs acclimated to 2 salinity and in crabs acclimated to 28 salinity, the drinking rate increased from approximately 0.4 ml 100 g-1 h-1 at 1 day prior to moult to approximately 8 ml 100 g-1 h-1 du...
متن کاملIn vitro Lymphoproliferative Responses of Trichostrongylus colubriformis High and Low Responder Guinea Pigs to Worm Antigens (SPL3, SPA) and Ovalbumin
In vitro lymphocyte responses of high responder (HR) and low responder (LR) guinea pigs from pe-ripheral blood lymphocytes (PBL) to parasite antigens soluble protein third stage larvae (SPL3) and soluble protein adult stage ( SPA), non-parasite antigen ovalbumin (OVA) were examined. There was substantial differences between HR and LR guinea pigs in the rate of acquisition of responsiveness to t...

15 صفحه اولChloride regulation at low salinities by Nereis diversicolor (Annelida, Polychaeta). II. Water fluxes and apparent permeability to water.
Evaluation of the chloride exchanges of Nereis diversicolor in the steady state has shown that this worm 'cuts its losses', i.e. reduces the fluxes, of chloride at very low salinities (Smith, 1970a), and that this reduction of chloride loss takes place mainly in the urinary component of the efflux, as has also been suggested by previous authors. Jorgensen & Dales (1957) measured the rates of os...
