title: Inhibition of PSII in atrazine-tolerant tobacco cells by barbatic acid, a lichen-derived depside.
abstract: In atrazine-tolerant tobacco cells with Ser to Thr mutation at the 264th amino acid of PsbA polypeptide in photosystem II (PSII), electron trannsport around the secondary quinone acceptor (Q(B)) site was inhibited to a greater extent by barbatic acid than in wild-type cells. Further characterization suggests similar mode of action of barbatic acid and phenyl-type herbicides.
