Pearl millet: A Genetic resource for abiotic tolerant Transgenics

In present times, abiotic stresses are becoming very prominent due anthropogenic caused changing global climate. Different plants are known to respond to abiotic stresses depending upon their characteristics and metabolic machinery. Responses can be observed at various levels, such as physiological, morpho-anatomical, phonological, biochemical and molecular level. As a result of ability of plants to respond against abiotic stress, the plant types are classified as tolerant and susceptible. Pearl millet (Pennisetum glaucum (L). R. Br.), a well known hardy crop among cereals is usually, grown under tropical dry areas of the world as it can survive under different abiotic stress conditions. Molecular studies of plants as Penniseteum glaucum L (Br) that are well adapted to high temperature stress can gives us some insight about the mechanisms of tolerance to abiotic stresses of a plant system. The understanding and the leads obtained would help in prospecting abiotic stress responsive genes which can be utilized for development of high temperature tolerant transgenics.
