Research ArticleOpen accessIn the abstractA Cyanobacterium Synechocystis sp. PCC 6803 Glutaredoxin Gene (slr1562) Protects Escherichia coli against Abiotic StressesAhmed Gaber, Salah El-Din El-AssalProblem statement: Glutaredoxins (GRXs) are ubiquitous small heat stable glutathione-dependent oxidoreductase enzymes that play a crucial role in plant development and response to oxidative stress. Approach: Cyanobacterium Synechocystis strain PCC 6803 contains two genes (slr1562 and ssr2061) encoding glutaredoxins. In the present investigation the slr1562 gene (grxC) was isolated and characterized. Results: The results revealed that the amino acid sequence … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Mar 2012 · 7,582 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Potassium Levels on Antioxidant Enzymes and Malondialdehyde Content under Drought Stress in Sunflower (Helianthus annuus L.)H. Soleimanzadeh, D. Habibi, M.R. Ardakani et al.Problem Statement: Drought stress as a major adverse factor can lower leaf water potential, leading to reduced turgor and some other responses and ultimately lower crop productivity in arid and semi arid zones. Sunflower is one of the main oil seed crops in Iran, where drought stress is the most limiting factor. Drought stress tolerance requires the activation of complex … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,779 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Super Absorbent Application on Antioxidant Enzyme Activities in Canola (Brassica napus L.) Cultivars under Water Stress ConditionsH. R. Tohidi-Moghadam, A. H. Shirani-Rad, G. Nour-Mohammadi et al.Problem statement: Drought stress significantly limits Canola (Brassica napus L.) growth and crop productivity. Hence, efficient management of soil moisture and study metabolic changes which occur in response to drought is important for agricultural production of this Crop. Approach: For a better understanding of drought tolerance mechanisms and improving soil water content management strategies, an experiment was laid out in … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 8,603 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 · 14,471 accessesView PDF Cite
