Abstract
The changes in the climate due to global warming and ever dwindling arable land due to
the population pressure are increasing strain on available resources for sustainable food
production. Therefore, it is an urgent need to have proper idea about the effect of drought
stress on crop plants for getting stable production through research intervention. Water
deficit due to drought stress influences a wide range of plant processes, from whole plant
growth and development to the molecular regulation of essential transcriptional pathways,
and thus significantly impacts both physiology and metabolism. The studies about the
changes in behavior of crop plants under drought condition have progressed at a rapid pace
and extensive results of such analysis have been made public through various research
articles, which can now be easily accessed through the World Wide Web. This review
describes some aspects of drought induced effect of drought stress on different important
traits of crop plants.
