Research ArticleOpen accessIn the abstractSalicylic Acid Protects Nitrate Reductase Activity, Growth and Proline in Amaranth and Tomato Plants during Water DeficitC. E. Umebese, T. O. Olatimilehin, T. A. OgunsusiProblem statement: Seedlings of Amaranthus hybridus cv. NHAC-3 (large green, amaranth) and Lycopersicum esculentum cv. Roma (tomato) were subjected to 7 days water stress at Early Vegetative (EV), Late Vegetative (LV), Early Flowering (EF) and Late Flowering (LF) stages of growth to study the impact on leaf water potential (ψw), Nitrate Reductase Activity (NRA), growth (plant height, shoot and root … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,569 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMapping QTLs Linked to Physio-Morphological and Plant Production Traits under Drought Stress in Rice (Oryza sativa L.) in the Target EnvironmentS. Michael Gomez, S. Satheesh Kumar, P. Jeyaprakash et al.Drought stress is a major constraint for rice (Oryza sativa L.) production and yield stability in rainfed ecosystems. Identifying genomic regions (QTLs) contributing in drought resistance will help to develop rice cultivars suitable for water-limiting environments through marker-assisted breeding. QTLs linked to physio-morphological and plant production traits under drought stress in the field were mapped by evaluating 177 F6 recombinant … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 14,482 accessesView PDF Cite

Research ArticleOpen accessIn the abstractElapse Time Factor on Induced Vegetative Moisture Uptake in an Unsaturated SoilMuazu Mohammed Abdullahi, Nazri Bn Ali, Kamarudin Bn Haj AhmedProblem statement: Soil consolidation is generally time dependent, therefore soil displacement as a result root water uptake is space and time dependent. The time-dependent nature of abstraction of ground water by vegetation need to be evaluated in order understand the effect of time elapse on matric suction a generation and subsequent ground displacement. Approach: The current approach used the theory … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 7,719 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Autistic Phenotype Exhibits a Remarkably Localized Modification of Brain Protein by Products of Free Radical-Induced Lipid OxidationTeresa A. Evans, Sandra L. Siedlak, Liang Lu et al.Oxidative damage has been documented in the peripheral tissues of autism patients. In this study, we sought evidence of oxidative injury in autistic brain. Carboxyethyl pyrrole (CEP) and iso[4]levuglandin (iso[4]LG)E2-protein adducts, that are uniquely generated through peroxidation of docosahexaenoate and arachidonate-containing lipids respectively, and heme oxygenase-1 were detected immunocytochemically in cortical brain tissues and by ELISA in blood plasma. Significant … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 8,727 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordValidation of the Ceres-Wheat for Prediction of Wheat Varieties in Irrigation and Terminal Drought StressFarzad Paknejad, Fatemeh Majidi Fakhr, Seied Mehdi MirtaheriProblem statement: Crop growth models have many potential uses for crop managements. Approach: In order to evaluation of CERES-Wheat model on five varieties of winter wheat in Karaj weather condition in Full Irrigation (FI) and Stop Irrigation (SI) after flowering until final growth stage an experiment conducted in shape of split plot in based on randomize complete block design with … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 16 Mar 2012 · 7,726 accessesView PDF Cite
