(h)GR, beans and drought stress [PDF]

Plant Signaling & Behavior, 2008
Reactive oxygen species (ROS) are commonly found in plants as natural by-products of the metabolism but their production is greatly enhanced under abiotic stresses. Particular metabolites and enzymes belonging to the ascorbate-glutathione cycle are able to scavenge these deleterious molecules and modulate the cellular redox-status.

Optimizing crop management strategies for improved yield, water productivity, and sustainability of quinoa in shallow basaltic semi-arid regions

Frontiers in Plant Science
IntroductionRecently, quinoa (Chenopodium quinoa Willd.) has gained global recognition as a nutritious, adaptable crop suitable to adverse soil and climatic conditions. However, knowledge about optimal management practices for its cultivation in marginal

Rubisco Activity: Effects of Drought Stress [PDF]

Annals of Botany, 2002
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) activity is modulated in vivo either by reaction with CO2 and Mg2+ to carbamylate a lysine residue in the catalytic site, or by the binding of inhibitors within the catalytic site. Binding of inhibitors blocks either activity or the carbamylation of the lysine residue that is essential for ...

Effects of drought stress on flowering soybean physiology under different soil conditions

Plant, Soil and Environment, 2022
Soybean is highly sensitive to drought stress during its flowering period. Heinong84 (HN84) and Hefeng46 (HF46) were planted in clay loam, silty loam, and sandy clay.

Characterization of gene expression associated with drought avoidance and tolerance traits in a perennial grass species. [PDF]

PLoS ONE, 2014
To understand molecular mechanisms of perennial grass adaptation to drought stress, genes associated with drought avoidance or tolerance traits were identified and their expression patterns were characterized in C4 hybrid bermudagrass [Cynodon dactylon ...

Optimum Nitrogen and Phosphorus Combination Improved Yield and Nutrient Use Efficiency of Sorghum in Saline Soil

Plants
Two-year experiments were conducted to assess the responses of yield and nutrient use efficiency of sorghum to nitrogen and phosphorus under saline soils. Three nitrogen rates (0, 180, and 360 N kg ha−1) and three phosphorus rates (0, 60, and 120 P2O5 kg

Mineral Nutrient Uptake, Accumulation, and Distribution in Cunninghamia lanceolata in Response to Drought Stress

Plants, 2023
Mineral accumulation in plants under drought stress is essential for drought tolerance. The distribution, survival, and growth of Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.), an evergreen conifer, can be affected by climate change, particularly ...

Influence of Diazotrophic Bacteria on Antioxidant Enzymes and Some Biochemical Characteristics of Soybean Subjected to Water Stress

Journal of Integrative Agriculture, 2012
Drought stress is an abiotic stress that imposes serious constraints on plants. The present investigation was carried out to determine the inter-relationship between some physiological attributes of soybeans affected by drought stress and pure isolates ...

Melatonin imparts tolerance to combined drought and high-temperature stresses in tomato through osmotic adjustment and ABA accumulation

Frontiers in Plant Science
In recent years, environmental stresses viz., drought and high-temperature negatively impacts the tomato growth, yield and quality. The effects of combined drought and high-temperature (HT) stresses during the flowering stage were investigated.

The combination of drought and heat stress has a greater effect on potato plants than single stresses

Plant, Soil and Environment, 2020
Several research groups have examined the effects of drought stress and heat stress on potato, but few investigations of the effects of combined drought-heat stress have been reported.
