Alkyl substituted 2-halogen-4-nitro-phenols (like bromonitrothymol) are potent inhibitors of photosynthetic electron flow in chloroplasts. There inhibition site is identical to that of DCMU, though the phenols do not contain their essential chemical element responsible for inhibition nor do they follow their correlation of chemical structure and biochemical function. Binding of labelled metribu...

Photosystem II particles that retain the ability to evolve 0 2 have been used to examine acceptor and inhibitor sites in the photosynthetic electron transfer chain between Q and plastoquinone. Employing the water to dichlorobenzoquinone reaction to assay photosystem II activity, we have demonstrated that electron transport in thylakoids and particles is equally sensitive to inhibition by DCM U,...

Contemporary farming practices and rapid industrialization over the last few decades, have raised significant soil water pollution with extreme toxic effects to humans ecosystems. The widespread inefficient use of pesticides, which surpass soil’s self purification capability, has accelerated pollution. In this study, wheat straw biochar was obtained using traditional pyrolysis technique its cha...
