The effects of NiSO4, calcium, and L-histidine (His) on the components of ascorbate-glutathione cycle, antioxidant enzymes and lipid peroxidation in a tomato cultivar Early Urbana Y was investigated. The activities of enzymes including catalase (CAT), guaiacol peroxidase (GPX), ascorbate peroxidase (APX), superoxide dismutase (SOD), glutathione reductase (GR), lipoxygenase (LOX), and phenylalanine...
Polyploidy has played a significant role in the evolutionary history of plants and is a valuable tool for obtaining useful characteristics. Because of the novelty of polyploids, comparison of their in vitro culture responses with diploids would be notable. In this study, leaf explants from diploid, autotetraploid and mixoploid plants of Cichorium intybus L. were cultured in vitro on the similar media...
Pollen of Lagerstroemia indica was collected from polluted (SO2, NOx, CO, HC, airborne particulate matter) and less polluted areas of Tehran city, Iran. Some pollen from less polluted areas was exposed to polluted air for 10 and 20 days. To determine the effect of air pollution on proteins, pollen extracts were analyzed by the Bradford method and SDS-PAGE. Study of pollen structure by light and scanning...
