Research ArticleOpen accessIn the keywordsOligoglucans as Elicitors of an Enzymatic Antioxidant System in Zucchini Squash (Cucurbita pepo L.) Seedlings at Low TemperatureAbel Ceron-Garcia, Gustavo Adolfo Gonzalez-Aguilar, Irasema Vargas-Arispuro et al.Abstract: Problem statement: Non-controlled low temperatures affect physiological and biochemical processes leading to Reactive Oxygen Species (ROS) accumulation in plants, which normally are stabilized by the antioxidant system. Superoxide Dismutase (SOD), Ascorbate Peroxidase (APX) and Catalase (CAT) are the most important ROS-detoxification enzymes in stressed plants. Approach: The activity of these enzymes were examined in response to fungal Oligoglucans (OG) … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,306 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsInfluence of Ionizing Radiation on Antioxidant Enzymes in Three Species of TrigonellaMuna M. Al-Rumaih, May M. Al-RumaihThe response of three species of Trigonella, namely, Trigonella stellata, Trigonella hamosa and Trigonella anguina to gamma irradiation stress was investigated with respect to antioxidant enzyme induction. When dry seeds were subjected to gamma rays (0, 40, 60, 80, 100 Krad) from a cobalt source 60Co at a dose rate of 233.5 rad/ min, a dose dependent increase in the … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 8,404 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Cement Dust on the Physiological Activities of Arabidopsis thalianaSaeid Abu-Romman, Jarrah AlzubiAir pollution exerts detrimental effects on plant ecosystems and restricts agricultural productivity. Cement dust is considered to be one of the most harmful air pollutants of industrial origin and is a limiting factor for plant growth and productivity. This study aims to uncover the impacts of cement dust on photosynthetic pigments, protein content, hydrogen peroxide (H2O2) accumulation, lipid per oxidation … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 17 Nov 2015 · 8,113 accessesView PDF Cite

Research ArticleOpen accessIn the abstractINDUCES OF ANTIOXIDANT COMPOUNDS AND SALT TOLERANCE IN WHEAT PLANT, IRRIGATED WITH SEAWATER AS RESPONSE TO APPLICATION OF MICROALGAE SPRAYHanaa H. Abd El Baky, M. M. Hussein, Gamal S. El-BarotyWheat plants (Triticum aestivum L., cv. Giza 168) irrigated with either 10 or 20% of Seawater (SW) were treated with aqueous extracts of green microalgae Scenedesmus obliquus and blue green algae Spirulina platensis (AESO and AESP 20 g (dry weight)/L) in order to increase wheat salt tolerance. Treated plants showed higher ability to tolerate salt stress (10 or 20% SW) … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 7 Jan 2014 · 7,591 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProteomics Approach for Investigating the Disease Resistance Using Cucumber as Model PlantSaligrama A. Deepak, Junko Shibato, Hideo Ishii et al.The profile of proteins induced in cucumber leaves pretreated with Acibenzolar-S-Methyl (ASM) and challenge inoculated with Colletotrichum orbiculare are presented. ASM was applied to the first leaf and the third leaf collected at different time intervals of 0-48 h and the total protein extracted using trichloroacetic acid acetone was analyzed by two-dimensional gel electrophoresis. Increased expressions of pyridoxine biosynthesis protein, … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 7,240 accessesView PDF Cite
