One of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. In order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...

drought stress due to water deficit and terminal temperatures is a serious problem in agriculture, and it is one of the most important factors contributing to crop yield loss. to evaluate drought tolerance of barley, 12 advanced barley genotypes were studied in two rainfed and irrigated conditions (in a subtropical region, gachsaran) in 2006-2007 in a rcb design with three replications. results...

SYNOPSIS. Drying to equilibrium with the air is lethal to most species of animals and plants, making drought (i.e., low external water potential) a central problem for terrestrial life and a major cause of agronomic failure and human famine. Surprisingly, a wide taxonomic variety of animals, microbes, and plants do tolerate complete desiccation, defined as water content below 0.1 g H2O g21 dry ...

In the natural environment plants are well adapted to minimize damages which only occurs under extreme conditions. In the frame of “physiological window” mild drought induces in plants regulation of water loss and uptake allowing maintenance of their leaf relative water content within the limits where the photosynthetic capacity shows no or little changes. But severe drought induces in plants u...

About one-third of the world's rice area is in rain-fed lowlands and most are prone to water shortage. The identification of genes imparting tolerance to drought in the model cereal plant, rice, is an attractive strategy to engineer improved drought tolerance not only rice but other cereals as well. It is demonstrated that RNAi-mediated disruption of a rice farnesyltransferase/squalene synthase...
