Functional Genomics for Tolerance to Abiotic Stress in Cereals uri icon

abstract

  • The world food grain production needs to be doubled bythe year 2050 to meet the ever growing demands of thepopulation (Tilman et al., 2002). This goal needs to be achieved despitedecreased arable land, dwindling water resources, and the environmentalconstraints such as drought, water logging, excess heat, frost, salinity, metaltoxicity and nutrient imbalances, which cause major losses in cereal grainproduction. Drought, salinity and cold stress alone are known to causenearly 35% of cereal crop losses throughout the world (Quarrie et al., 1999).The effectiveness of traditional breeding approaches to deal with theproblem is limited due to complex nature of stress tolerance traits and due toincompatibility barriers encountered during transfer of genes from wildspecies to cultivated ones. Therefore, newer strategies need to be used fordeveloping crop plants that
