nr 1

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 electron microscopy showed that air pollution increased the number of shrunken and fragile pollen. Particle agglomeration and cellular material release were increased in polluted pollen. Total protein content and the staining intensity of protein bands by SDS-PAGE were decreased in polluted pollen.
