Reversible Deformation of Transfusion Tracheids in Taxus baccata Is Associated with a Reversible Decrease in Leaf Hydraulic Conductance.
Declines in leaf hydraulic conductance (Kleaf) with increasing water stress have been attributed to cavitation of the leaf xylem. However, in the leaves of conifers, the reversible collapse of transfusion tracheids may provide an alternative explanation. Using Taxus baccata, a conifer species without resin, we developed a modified rehydration technique that allows the separation of declines in ...
متن کاملLow leaf hydraulic conductance associated with drought tolerance in soybean.
Lack of water is the most serious environmental constraint on agricultural production. More efficient use of water resources is a key solution for increased plant productivity in water-deficit environments. We examined the hydraulic characteristics of a 'slow wilting' phenotype in soybean (Glycine max Merr.), PI 416937, which has been shown to have relatively constant transpiration rates above ...
متن کاملReversible swelling of SBMV is associated with reversible disordering
The structures of the compact and swollen southern bean mosaic virus (SBMV) particles have been compared by X-ray diffraction and proton magnetic resonance (PMR). Small-angle X-ray scattering showed that removal of divalent cations at alkaline pH causes the particle diameter to increase from 289Å in the native SBMV by 12% in solution and by 9% in microcrystals. The swelling is fully reversible ...
متن کاملReversible Pulmonary Hypertension in an Infant Treated with Diazoxide
Background: Diazoxide is the main therapeutic agent for congenital hyperinsulinism. The drug is generally well tolerated; however, in this report severe adverse effects including heart failure (HF) and pulmonary hypertension (PH) in an infant are reported.Case report: A sixteen-day male infant with persistent hypoglycemia and with diagnosis of congenital hyperinsulinism underwent near total pan...
متن کاملDesigning of Testable Reversible QCA Circuits Using a New Reversible MUX 2×1
Recently testing of Quantum-dot Cellular Automata (QCA) Circuits has attracted a lot of attention. In this paper, QCA is investigated for testable implementations of reversible logic. To amplify testability in Reversible QCA circuits, a test method regarding to Built In Self Test technique is developed for detecting all simulated defects. A new Reversible QCA MUX 2×1 desig...
