Regulation of gene expression during water deficit stress

Plant Growth Regulation, 1999
Water deficit is one of the most important environmental stress factors limiting the growth and productivity of agronomically important plants. Plant responses to water deficit are complex, involving the co-ordination and integration of multiple biochemical pathways leading to the expression of a number of genes encoding proteins which contribute to ...

Response of sugarcane genotypes to water deficit stress

Sugar Tech, 2004
Drought is one of the major constraints for sugarcane cultivation, which necessitates the development of drought resistant varieties. The drought situation prevailed at Coimbatore (India) during 2003 was utilized to study the performance of 97 high sugared genotypes under water deficit situation.

SUPPRESSION OF IRRIGATION WATER DEFICIT STRESS AFFECTING SOYBEAN PRODUCTION

Journal of Global Agriculture and Ecology, 2022
Drought phenomena have been frequenting in Egyptian history. So, the drought in the agricultural sector is a particularly important area to be examined. Therefore, a field experiment was  carried out to  evaluate three irrigation intervals as main factor [irrigation every 7, 9 and 11 days], soil addition of some conditioners [ control ( without ...

Water Deficit Stress Effects and Responses in Maize

2019
Scarcity of water is a severe environmental restriction to plant productivity. Crop growth and yields are negatively affected by sub-optimal water supply due to physical damages, physiological disruptions, and biochemical changes. Here, we have reviewed the effects of water deficit stress on the germination and growth, water and nutrient relations ...

Effects of water deficit and salinity stress on late mandarin trees

Science of The Total Environment, 2022
To maintain the viability of citrus farms in a scenario of scarce water supplies for irrigation purposes, such as in south-eastern Spain, it is necessary to detect the maximum threshold of crop water status and vegetative growth, both of which are vulnerable to the combined effect of water and salinity stress.

Sunflower seedlings subjected to increasing water deficit stress: oxidative stress and defence mechanisms

Physiologia Plantarum, 1995
Sunflower seedlings (Helianthus annuus cv. Licia Stella) reached a mild, moderate and severe level of water deficit stress after 5, 8 and 11 days of soil water depletion, respectively. At a moderate level of water deficit stress, an elastic adjustment occurred.

Functional Characterization of Water-Deficit Stress Responsive Genes Using RNAi

2010
In response to water-deficit stress, plants alter expression of thousands of genes and as a result, cellular, physiological, and biochemical processes are modified. Understanding the functional role of water-deficit stress-responsive genes is important in order to develop stress-tolerant plants.

Identification of Water Deficit Stress Upregulated Genes in Sugarcane

Plant Molecular Biology Reporter, 2010
Sugarcane represents an important renewable source among biofuel crops with high capability to assimilate carbon among the C4 plants. Limited availability of freshwater renders this crop uneconomical, warranting the necessity for the development of varieties with higher water use efficiency and tolerant to water deficiency stress. Sugarcane variety cv.

Leaf epidermal plasticity in response to water deficit stress

2022
A thesis concerning the effects of water deficit on stomatal traits in plants. The relationships between different traits and their influence on overall stomatal anatomy is discussed. Genetic work to investigate molecular regulation of stomatal development is also presented and discussed.

Stomatal sensitivity to abscisic acid following water deficit stress

Journal of Experimental Botany, 1994
Short- and medium-term stresses (1 and 24 h, respectively) were applied to detached leaves of Commelina communis L., resulting in both cases in a final leaf cell water potential (ψ w ) of about -1.0 MPa and relative water content (RWC) of about 74%. A long-term stress (14 d), applied to intact plants, resulted in a final leaf cell Ψ w of -0.57 MPa and
