During the last century, we have assisted to an extraordinary increase of crop yields, especially for the most widespread and consumed crop species, such as rice, wheat, corn and soybean. The Broadbalk experiment, one of the oldest continuous agronomic experiments in the … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 4 Jun 2016 · 8,399 accessesView PDFCite
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 PDFCite
