In field conditions, plants are concurrently exposed to multiple stresses, where one stressor impacts the plant's response to another stressor, and the resultant net effect of these stresses differs from individual stress response. The present study investigated the effect of drought stress on interaction of chickpea with Pseudomonas syringae pv. phaseolicola (Psp; foliar pathogen) and Ralstoni...

the response of plants to drought stress depends on several factors including the plant developmental stage and the length and severity of the stress applied. common bean (phaseolus vulgaris l.) is the most important pulse crop that is cultivated worldwide for human consumption. understanding of the mechanisms responsible for its response to drought is, therefore, essential. an increasing numbe...

Arbuscular mycorrhizal (AM) symbiosis is generally considered to be effective in ameliorating the plant tolerance to salt stress. Unfortunately, the comprehension of the mechanisms implicated in salinity stress alleviation by AM symbiosis is far from being complete. Thus, an experiment was performed by growing durum wheat (Triticum durum Desf.) plants under salt-stress conditions to evaluate th...

The present work aimed at investigating changes in growth and some metabolic activities in NaCl-stressed bean plants, and assessing the role of ascorbic acid to alleviate these changes. The field experiment was carried out to study the response of presoaked fava bean seeds (Vicia fava cv. Misr 2) in freshly prepared ascorbic acid (50 ppm ≈ 0.3 mM; as recommended dose as described by  El-Tayeb, ...

To study drought stress effects on bound water, adsorption isotherms and pressure-volume curves were constructed for two durum wheat (Triticum durum Desf.) cultivars: Capeiti 8 (drought tolerant) and Creso (drought sensitive). Plants were grown under well-watered and water-stressed conditions in a controlled environment. Differential enthalpy (DeltaH) was calculated through van't Hoff analysis ...

In stressed plants, the reactive oxygen species (ROS) levels rise. Key to ROS signaling research are detection and identification of the protein cysteine sulfenylation (-SOH), the ROS-mediated oxidative product of a thiol (-SH). Arabidopsis thaliana seedlings were stressed with hydrogen peroxide (H2O2) and the sulfenylated proteins were tagged with dimedone. Dimedone-tagged sulfenic acid protei...
