Five-week-old tomato plants (Lycopersicon esculentum) cv. Perkoz grown in pots containing garden soil in a growth chamber were submitted to 50 or 150 mM NaCl for 1 h, 2 and 5 days. Tomato leaf anatomy generally did not change after short time salinity, except 5-day-treatment with 150 mM NaCl, where changed cell shape (shrunk and deformed) simultaneously with increased volume of intercellular sp...
متن کاملLipoxygenase pathway and antioxidant system in salt stressed tomato seedlings (Lycopersicon esculentum Mill.)
Soil or growing media salinity is an increasing problem in agriculture throughout the world. Therefore, there is a real interest in a better understanding of the mechanisms set by the plants to respond to this stress. The present study concerns tomato, which is one of the most important cultivated vegetables. Tomato seeds (Lycopersicon esculentum var. 'Moneymaker') were disinfected and a salt s...
متن کاملIn vitro flowering and fruiting in tomato (Lycopersicon esculentum Mill.)
In vitro flowering and fruiting were induced in plants regenerated from calli of leaf explants of Lycopersicon esculentum var. Pant 11. MS medium supplemented with 2 mg/l BAP displayed the best response followed by MS with 2 mg/l BAP, 1 mg/ l ABA and 0.5 mg/l IAA. Flower buds were developed both directly from callus and regenerated plantlets from leaf explants under 16 h (39.3 μmol m-2s-1) phot...
متن کاملMolecular 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 کاملPurification and Characterization of Tomato Leaf (Lycopersicon esculentum Mill.) Hydroperoxide Lyase
Hydroperoxide lyase (HPOOH lyase) was extracted from tomato leaves (Lycopersicon esculentum Mill.) and purified to apparent homogeneity by fractionated precipitation with polyethylene glycol 6000, ion exchange chromatography, and ultrafiltration. The enzyme is a trimer of 73 000 Da units with a molecular mass of 216 000 (determined by native-PAGE and gel filtration); its pI is around 4.9. Enzym...
