Research ArticleOpen accessIn the abstractEnhancement of Nutritional Quality of Wheat (Triticum aestivum) by Metabolic Engineering of Isoflavone PathwayAhmed Mohamed El-Shehawi, Abdelmegid Ibrahim Fahmi, Mona Mohamed Elseehy, Hesham Ahmed NagatyIsoflavones are large group of secondary metabolites produced in legumes such as soybeans. They have essential biological functions as nutraceutical and health functions for human. They are involved in plant resistance to biotic and abiotic stresses, symbiotic relationship with nitrogen-fixing organisms and plant competition (allelopathy). In this report, isoflavonoids were expressed in wheat (Triticum aestivum) via introducing the key enzymes … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,135 accessesView PDF Cite
