The stress-responsive genes expressed against the exogenous addition of dibenzo-p-dioxin from the lignin-degrading basidiomycete, Phanerochaete chrysosporium, were determined utilizing a differential display reverse transcription-PCR technique. Six cDNA fragments, exhibiting a high homology with various proteins from other microorganisms, were identified via a BLAST search; that is, NADH-ubiquinone oxidoreductase (NUO), ATP/ADP carrier, uric acid-xanthine permease, manganese superoxide dismutase, 3-hydroxybutyryl-coenzyme A dehydrogenase, and cytoskeletal protein. The expression of NUO was also up-regulated by catechol and trihydroxybenzene but not by dibenzofuran, suggesting that NUO expression was initiated by the formation of quinone products through the reaction of extracellular one-electron oxidizing enzymes with dibenzo-p-dioxin.
