Water, the most important component of life, is rapidly becoming a critically short commodity
for humans and crop production. Limited water supply is one of the major abiotic factors that …

Drought is a climatic phenomenon that can occur periodically in all climatic zones, but
occurs with greater frequency in tropical and subtropical regions, causing physiological …

In natural and agroecosystems, plants are continuously exposed to several environmental
stress factors. Besides having evolved several indigenous tolerance mechanisms, proper …

Decreasing water availability under drought generally results in reduced total nutrient
uptake and frequently in reduced concentrations of mineral nutrients in crop plants. The …

Plants are continuously exposed to various environmental stresses, which cause alteration
in every physiological and biochemical pathway. Plants have evolved several mechanisms …

Drought, the occurrence of a substantial water deficit in the soil or in the atmosphere, is an
alarming constraint to crop productivity and yield stability worldwide. It is the leading …

By the year 2050, the world's population is predicted to have grown to around 9–10 billion
people. The food demand in many countries continues to increase with population growth …

Scarcity of water is a severe environmental constraint to plant productivity. Drought-induced
loss in crop yield probably exceeds losses from all other causes, since both the severity and …

The increasing frequency of dry periods in many regions of the world and the problems
associated with salinity in irrigated areas frequently result in the consecutive occurrence of …

Control of drought stress in plant is not only very complex, but is also highly influenced by
other environmental factors and by the developmental stage of the plant. Here we review …
