Bisphenol A (BPA) is an emerging environmental pollutant with potentially toxic effects on living organisms. The present study was undertaken to analyze the effects of BPA on the leaves of Arabidopsis thialina by determining the levels of photosynthetic pigments, reactive oxygen species (ROS), membrane lipid peroxidation, and ultrastructural malformation. The obtained results revealed that while a...
Light environments can have a considerable influence on how plants respond to defoliation through influencing the biomass allocation patterns and internal C/N ratio. Seedlings of Lolium perenne, a common perennial grass species, were grown for eight weeks under three different light environments (natural light, red light and shading) and two different defoliation treatments (no defoliation versus...
To explore regulated mechanisms of Brassinosteroids-induced chilling tolerance, we studied the involvement of foliar sprayed 24-epibrassinolide (EBR) in the growth, lipid peroxidation, distribution of absorbed energy and excitation energy, chlorophyll fluorescence characteristics and antioxidant defense system of pepper seedlings under chilling stress. We found that low temperature retarded the growth...
