Rhizospheric actinobacteria of Opuntia sp. “prickly pear” with deaminase activity as growth promoting in Solanum lycopersicum L. under salinity stress

Physiological and Proteomic Analysis in Chloroplasts of Solanum lycopersicum L. under Silicon Efficiency and Salinity Stress

Tomato plants often grow in saline environments in Mediterranean countries where salt accumulation in the soil is a major abiotic stress that limits its productivity. However, silicon (Si) supplementation has been reported to improve tolerance against several forms of abiotic stress. The primary aim of our study was to investigate, using comparative physiological and proteomic approaches, salin...

Comparative proteomic analysis of tomato (Solanum lycopersicum) leaves under salinity stress

Salinity is a major constraint to crop productivity. The mechanisms responsible for the effects of salt stress on tomato plants were examined by means of proteomic analysis. Two contrasting tomato genotypes (cv. Roma and cv. SuperMarmande) seedlings were cultivated using a hydroponic system in the controlled environment growth chamber. The salt stress (NaCl) was applied (0, 100 and 200 mM) and ...

Physicochemical Characteristics of Moroccan Prickly Pear Juice (Opuntia ficus indica L.)

The cactus prickly pears rich in micronutrients, has recently generated a great deal of consumer interest, therefore, this paper was designed to study its physical and chemical compositions such as: moisture, sugar content, total fibres, protein, ash, pH, acidity, minerals contents and total phenolics contents of nine prickly pear juices. Polyphenols are antioxidants who contribute to the nutri...

Effect of seed priming with selenium nanoparticles and plant growth promoting rhizobacteria on improving Quinoa seedling growth under salinity stress

Soil and water salinity are the most important problems that limit crop production, especially in the arid and semi-arid regions. This study was conducted to investigate the effect of growth-promoting bacteria and selenium nanoparticle pretreatment on increasing the tolerance of the Chenopodium quinoa plant to salinity. A factorial experiment was conducted in a completely randomized design with...
