Summary

Abiotic stresses are the principal causes of crop failure, reducing average yields of most major crops by more than 50%. Rice and wheat are the two most important food crops in the world, together occupying about 28% of all crop area. A considerable amount of crop biomass for which genetic potential exists in the present-day cultivars in wheat and rice is not harvested under field conditions, primarily because of the sensitivity of these crops to various stresses. To meet human needs by 2050, grain production must increase at an annual rate of 2% on an area of land over what is being produced at present. Modern biotechnology has a lot to offer in the field of crop improvement in the present scenario both in understanding the mechanisms of stress and stress tolerance in plants and in developing crop plants better equipped for harsher environmental conditions. A great deal of research has been carried out in the recent past in the field of plant abiotic stress tolerance encompassing genomics, transcriptomics, proteomics, and metabolomics. These “omic” technologies investigate different facets of a given scientific issue such as abiotic stress tolerance, but complement each other. Integration of phenotypic, genetic, transcriptomic, proteomic, and metabolomic data will enable accurate and detailed gene network reconstruction. This chapter discusses the recent “omic” studies in wheat and rice in the field of abiotic stress tolerance.
