Background: Salinity is a major environmental limiting factor, which affect agricultural production. The two Manilkara seedlings (M. roxburghiana and M. zapota) with high economic importance, could not adapt well to higher soil salinity and little is known about their proteomic mechanisms. Objectives: The mechanisms responsible ...

In order to understand the response of tobacco (Nicotiana tabacum L.) to salt stress, the comparative analysis of leaf proteome of Basma S. 31 genotype were performed. Plants were treated with or without 200 mM NaCl for 12 days. The proteins were extracted from leaves, and then separated by two-dimensional electrophoresis. The fresh weight and length of shoot of studied genotype showed greater ...

Mixtures of chemicals can have additive, synergistic or antagonistic interactions. We investigated the effects of the exposure to nickel, the organophosphate insecticide chlorpyrifos at effect concentrations (EC) of 25% and 50% and their binary mixture (Ec25 + EC25) on Dictyostelium discoideum amoebae based on lysosomal membrane stability (LMS). We treated D. discoideum with these compounds und...

drought and salinity stress are adverse environmental factors that affect crop growth and yield. abiotic stress cause some reaction in plants such as change in gene expression, cell metabolism, growth and yield. moreover, stress condition resulted in increase of reactive oxygen species and disturbe macromolecules such as proteins, fatty acids, nucleic acid and pigments. in order to evaluate sal...
