New molecular tools to improve the efficiency of breeding for increased drought resistance, plants and provided not only geneticists, but also physiologists, agronomists and breeders with valuable new tools to identify traits of importance in improving resistance to abiotic stresses. For the breeder, a genetic map saturated with molecular markers allows selection for certain characters to

We can all tell that a cactus is more drought tolerant than a carnation. But when we look at crop plants, the features that confer drought tolerance are far fro

The strategies of adaptation to drought have been listed in regard of the level of organization: molecules, cells, whole plant. Root development and water uptake, transpiration and mic

In this range, leaf water potential and cell turgor are frequently maintained at high values in spite of decreasing soil water status. As a consequence, ‘water stress’ cannot be defined by plant water status, except wh

The participation of the plant hormone abscisic acid (ABA) has been well established. ABA levels increase when there are changes in the environment that result in cellular dehydration. D

The studies have used a variety of experimental strategies, and they have resulted in the characterization of a large number of genes which are expressed upon dehydration. A very prominent group among these genes are the so-called Lea (=late embryogenesis abundant)
