Alteration in PS II heterogeneity under the influence of polycyclic aromatic hydrocarbon (fluoranthene) in wheat leaves (Triticum aestivum)

Abstract

Polycyclic aromatic hydrocarbon, fluoranthene causes significant inhibitory effects on photosynthetic processes, particularly photosystem II. PS II exhibits heterogeneity with regards to antenna size, connectivity and ability to transfer electron beyond QA. This is the first report describing effects of FLT on PS II heterogeneity. FLT affects antenna heterogeneity by converting active α center into inactive β and γ centers. At the same time in the presence of FLT number of QB-non reducing center also increase. Such study can prove to be a biomarker for early detection to stress tolerance and toxicity of environment pollutants.
