Salinity commonly affects photosynthesis and crop production worldwide. However, some studies have shown that hydrogen peroxide seed priming can increase the tolerance of plants to salt stress. In this context, study aimed test hypothesis H2O2 improve photosynthetic efficiency in sunflower under The experiment was conducted a completely randomized design, with four replicates. Six treatments we...

Hydrogen peroxide priming has emerged as a powerful strategy to trigger multiple responses involved in plant acclimation that reinforce tolerance abiotic stresses, including salt stress. Thus, this study aimed investigate the impact of foliar H2O2 on physiological, biochemical, and ultrastructural traits related photosynthesis salt-stressed plants. Besides, we provided comparative leaf metabolo...

We have used a cytofluorometric method to study the effect of tumor necrosis factor alpha (TNF) priming on the oxidative burst, FMLP-receptor expression and actin polymerization of whole blood polymorphonuclear neutrophils (PMN). This technique permits the study of single cells and, thus, allowed us to examine the responsiveness of PMN to TNF in whole blood. We found that TNF in whole blood str...

The eosinophil is recognized as an important effector cell in asthma. To investigate the role of eosinophils in the aetiology of asthma, we have examined whether peripheral blood eosinophils are primed following whole-lung allergen challenge. Nineteen mild asthmatics, who each demonstrated a late asthmatic response (LAR), were studied. The priming of eosinophils following allergen challenge was...

The influence of seed priming with varying levels (50 and 100 mg L?1) alpha-tocopherol (Toc) was investigated in carrot plants under water-deficit conditions. For this purpose, two cultivars carrot, DC4 DC90, were selected subjected to well-watered (100% field capacity (FC)) stress (50% FC). After 21 days conditions, a significant suppression observed shoot root fresh dry weights, their lengths...

Drought is the major abiotic stress that decreases plant water status, inhibits photosynthesis, induces oxidative stress, restricts growth and finally lead to the reduction of wheat yield. It has been proven that drought priming during vegetative growth stage could enhance tolerance to drought stress at grain filling in wheat. However, whether drought priming imposed at grain filling in parenta...

Fusarium wilt is one of the major causes global losses in banana industry. The application extracellular DNA (eDNA) explored as a natural fungicide. eDNA categorized on basis receiving cell’s perception, namely self and non-self. self-eDNA agriculture presents potential for limiting growth pathogens, while non-self-eDNA, vaccine plants. This study evaluated whether from oxysporum f. sp. cubense...

The use of salt stress attenuators is considered an important tool to minimize the deleterious effects salts. However, its application chives (Allium schoenoprasum L.) has not been studied. This study aimed evaluate induction tolerance in plants relation growth and enzymatic reactions, when subjected different salinity levels nutrient solution, after acclimation seeds with hydrogen peroxide (H2...

Welsh onion (Allium fistulosum L.) is one of the important vegetable crops in China. However, the seeds of this crop are short-lived and their vitality tends to be easily lost in the course of storage. The present study was conducted to elucidate the effects of welsh onion seed priming with potassium nitrate (KNO3) on seed vigor and on other such related mechanisms during twelve months of stora...

We examined the effect of cardioprotective agents on three distinct phases of the H2O2-induced response that leads to loss of mitochondrial membrane potential (DeltaPsi(m)) and cell death in cultured cardiac myocytes: (1) priming, consisting of calcium-dependent morphological changes in mitochondria (swelling and loss of cristae), with preserved DeltaPsi(m), (2) depolarization, the rapid DeltaP...
