Abstract

Plants face to different changes in environmental conditions that keep on challenging its normal growth and acclimatization. Cereal crops play a key role in supplying food and energy to growing population and these crops are bare to substantial environmental changes causing inferior growth and performance. To overcome the abiotic stresses experienced by plants, several differential molecular and physiological responses were evolved that make the plants to mitigate climatic aberrations. Latest technological developments in genetic engineering as well as molecular breeding register a significant role in developing crop varieties and hybrids those are tolerant to environmental aberrations. Several Transgenes and their Quantitative Trait Locus (QTL) were invented and incorporated into crops for superior performances against abiotic factors in cereals like wheat and rice.

• Growth and productivity of cereals are hampered due to abiotic stresses and under the present context of climate change there is the need for adoption of suitable measures.

• Understanding molecular mechanisms are important for development of suitable varieties/hybrids of cereals combatting ill effects of abiotic stresses.
