| 5 | Seasonal dynamics of foliar antioxidative enzymes and total anthocyanins in natural populations of Iris pumila L.显示文摘Aims Plants in their natural habitats frequently cope with a multitude of abiotic stresses,such as high light intensity,extreme temperatures and water deficit,which often co-occur during periods of drought,especially in semi-arid and arid regions.Exposure of plants to stressful environmental conditions usually induce overproduction of reactive oxygen species(ROS)that,as highly toxic derivatives of O_(2),can assault all cell macromolecules,leading to the disruption of cellular homeostasis and,consequently,the uncoupling of major metabolic processes,the photosynthesis and photorespiration.In order to minimize ROS-mediated cellular damage,plants have evolved highly efficient antioxidative defense systems that include both enzymatic and non-enzymatic components.Since abiotic stress can also operate as a strong evolutionary force that shapes adaptations in natural plant populations,the aim of this study was to examine the seasonal variation patterns of two distinct antioxidative systems,ROS-scavenging enzymes and anthocyanin pigments,in the leaf tissue of a steppe plant,Iris pumila,as expressed under contrasting light conditions that the species regularly experiences in the wild.Methods We selected two natural populations of I.pumila inhabiting the alternative radiation environments in the Deliblato Sands,a sunexposed dune site and a woodland understory.The specific activity of three antioxidative enzymes,superoxide dismutase(SOD),catalase(CAT)and peroxidase(POD)and the content of total anthocyanins were examined in leaves of I.pumila plants collected from each of the 31 Iris clones(17 in the exposed population and 14 in the shaded population)once during each of the three seasons,spring,summer and autumn in 2004.Specifically,a fully expanded leaf was cut from each clonal plant between 15:00 and 16:00 h,immediately frozen in liquid nitrogen and stored at-70℃until preparation.Important Findings Generally,all three antioxidative enzymes were up-regulated in summer-harvested leaves compared to their spring or autumn counterparts,as was observed for the concentration of foliar anthocyanins,indicating that strengthening of antioxidant systems was the key mechanism for long-term acclimatization of I.pumila plants to stressful environmental conditions within their natural ecological niches.When plants from contrasting radiation environments were compared,SOD and CAT activities appeared to be greater in shade-exposed than in sun-exposed leaves.Conversely,POD activity and the content of foliar anthocyanins were notably higher in foliage experiencing full sunlight relative to those developed under vegetation canopy,suggesting the synergistic function of these two molecules in protecting leaf cells against photoinhibitory and photooxidative effects of strong light. | Ana Vuleta Sanja Manitasevic Jovanovic Darka Seslija Branka Tucic | 2010 | Journal of Plant Ecology2010，3，1： | 1 |

| 11 | Exact Computation of the Topology and Geometric Invariants of the Voronoi Diagram of Spheres in 3D显示文摘In this paper, we are addressing the exact computation of the Delaunay graph (or quasi-triangulation) and the Voronoi diagram of spheres using Wu's algorithm. Our main contributions are first a methodology for automated derivation of invariants of the Delaunay empty circumsphere predicate for spheres and the Voronoi vertex of four spheres, then the application of this methodology to get all geometrical invariants that intervene in this problem and the exact computation of the Delaunay graph and the Voronoi diagram of spheres. To the best of our knowledge, there does not exist a comprehensive treatment of the exact computation with geometrical invariants of the Delaunay graph and the Voronoi diagram of spheres. Starting from the system of equations defining the zero-dimensional algebraic set of the problem, we are applying Wu's algorithm to transform the initial system into an equivalent Wu characteristic (triangular) set. In the corresponding system of algebraic equations, in each polynomial (except the first one), the variable with higher order from the preceding polynomial has been eliminated (by pseudo-remainder computations) and the last polynomial we obtain is a polynomial of a single variable. By regrouping all the formal coefficients for each monomial in each polynomial, we get polynomials that are invariants for the given problem. We rewrite the original system by replacing the invariant polynomials by new formal coefficients. We repeat the process until all the algebraic relationships (syzygies) between the invariants have been found by applying Wu's algorithm on the invariants. Finally, we present an incremental algorithm for the construction of Voronoi diagrams and Delaunay graphs of spheres in 3D and its application to Geodesy. | Franois Anton Darka Mioc Marcelo Santos | 2013 | Journal of Computer Science & Technology2013，28，2： | 0 |
