Molecular and biochemical protective roles of sodium nitroprusside in tomato (Lycopersicon esculentum Mill.) under salt stress
Salinity stresses act as inhibitor factors of plant growth. They can change the physiological characteristics and limit the production of crops. Sodium nitroprusside (SNP) is a stable free radical which use as a signalling molecule in plants and participates in various plant’s physiological, biochemical and molecular processes and also in plant’s responses to environmental stresses. We investig...
متن کاملProteomic analysis of salt-stressed tomato (Solanum lycopersicum) seedlings: effect of genotype and exogenous application of glycinebetaine
An investigation aimed at a better understanding of the molecular adaptation mechanisms of salt stress was carried out in 7-d-old tomato Solanum lycopersicum (L.) Mill cultivars Patio and 'F144', using a proteomic approach. Total proteins were extracted from radicles and hypocotyls collected from both non-saline control and salt-stressed seedlings, and separated by two-dimensional gel electroph...

Salinity is known as one of the most important abiotic factors that limit growth and yield of crop plants. This research was conducted to evaluate the effect of mycorrhiza symbiosis on physiological responses of Solanum lycopersicum against salinity stress. Three Solanum lycopersicum genotypes with and without mycorrhiza fungi and three levels of salinity stress (non-saline (control), mild (4 d...
متن کاملThe Solanum lycopersicum Zinc Finger2 cysteine-2/histidine-2 repressor-like transcription factor regulates development and tolerance to salinity in tomato and Arabidopsis.
The zinc finger superfamily includes transcription factors that regulate multiple aspects of plant development and were recently shown to regulate abiotic stress tolerance. Cultivated tomato (Solanum lycopersicum Zinc Finger2 [SIZF2]) is a cysteine-2/histidine-2-type zinc finger transcription factor bearing an ERF-associated amphiphilic repression domain and binding to the ACGTCAGTG sequence co...
متن کاملPhysiological 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...
