Abstract
With the advancement of biotechnological tools and techniques such as next generation sequencing, RNAomics, epigenomics, gene silencing, plant, microbe transformation, proteomics and metabolomics, the understanding of metabolic pathways and their manipulation for the desired characters became feasible. Metabolic engineering has been successful in the production of golden rice, bioprocess for artemisinin production, flavonoids in plant and microbes as well as generated biotic and abiotic stress tolerance in several crop plants. In view of the significance of metabolic engineering, this article includes recent techniques developed and their use in manipulation of glyoxalase metabolism for multiple abiotic stress tolerance in plants. The importance of engineering of flavonoids pathway for high value antioxidants production as well as improving the biotic and abiotic stress tolerance has been documented. Importance and success of metabolic engineering has been realized by its promising hope for sustainable technologies of bioactives production for mankind’s health as well as in the generation of improved crop varieties.
