Are there universal genetic traits to increase yields under water-deficit conditions?
Plant response to water-deficit conditions actually depends both on the interaction among a very large number of plant traits at all levels of organization from the molecular level through to the whole plant, and on a number of factors in the physical environment. The dynamic interaction of plant and environment variables makes the rate of water use an emergent property of those particular circumstances. The rate of water use to a large extent defines the nature of the water deficit and the response of plants to the stress. Consequently, there is usually not a single factor that controls crop response to developing drought but rather, a number of variables are collectively involved in influencing the ultimate impact of water deficit on crop performance. The consequences of various plant traits and environmental conditions have to be evaluated in the specific environments in which the crop is to be grown, that is field evaluations (Condon et al., 2004).
