Engineering cereal crops for enhanced abiotic stress tolerance

In the scenario of global climate change, abiotic stresses such as rising temperature, water deficit and stress combinations are posing serious threats to sustainable agricultural production, these factors account for more yield losses than any other factor. Developing crop plants with enhanced tolerance has become a priority now-a-days. Agricultural biotechnology including genomics-assisted breeding genetic engineering help in studying understanding complex nature responses provide measures enhancing productivity under adverse environmental conditions. Plants respond adapt by activating molecular network cascades that implicated perception, signal transduction, genes expression accumulation certain metabolites. Various functional genomics approaches have helped identify numerous involved stress-associated regulatory networks both model non-model species. Thus activate transcription responsive or play important roles protection maintenance cellular components macromolecules might expedite improvement programs. Several candidate been transformed agriculturally crops improve their tolerance. Nonetheless, not only encompasses attempts engineer “single action genes” “gene pyramiding” but also introgressions machinery involving factors. Further, development transgenic depends upon success rate transformation proper integration evaluation This review thus, summarizes recent progress application and/or technology order realize food security developing varieties superior
