title: The Involvement of Plastoquinone in the Pyocyanine-mediated Cyclic Electron Transport around Photosystem I.
abstract: 2,5 dibromo-3-methyl-5-isopropyl-p-benzoquinone (DBMIB), an inhibitor of plastoquinone, inhibited photosystem I cyclic electron transport mediated by pyocyanine of low concentration, but had no effect on that mediated by phenazine methosulphate (PMS). In the presence of pyocyanine, the thylakoids displayed a transient post-illumination increase in chlorophyll fluorescence which resembled that displayed in leaves. The above results indicate the involvement of plastoquinone in the pyocyanine-mediated cyclic electron transport around photosystem I.
