Abstract :
Crop plants are known to be affected by various types of stresses both natural and manmade. Abiotic stresses like drought and salinity have already been pronounced worldwide causing significant crop losses. Plants adapt to environmental stresses by accumulation of low molecular weight osmolytes such as proline and polyamines (PAs). In past two decades, polyamines have received considerable attention due to its wide range of functions in cellular metabolism, especially in response to wide variety of environmental stresses. Several mutant studies have shown positive changes in activities of PA biosynthetic enzymes for mitigation of stress condition. Studies with exogenous application of PAs have shown the successful alleviation of stress–induced damaging effects on plants. Genes encoding PA biosynthetic enzymes has been well characterised and being used in transgenic approach to get more insights into the role PAs under stress condition. This review focusses on recent developments in transgenic approaches that are being followed with PAs for enhanced stress tolerance in crop plants. Lastly, the novel transgenic approaches for improved stress tolerance have been depicted.
