The occurrence of denitrification and nitrate respiration among eukaryotes has been established during the last few decades. However, denitrification-related eukaryotic genes have been isolated from only a few fungi, and eukaryotic denitrification (or nitrate respiration) is still inadequately understood. In this study, we identified genes that were up-regulated under denitrifying conditions in the fungus Cylindrocarpon tonkinense using the suppression subtraction hybridization technique, and the expression patterns of these genes were characterized by Northern analysis. We identified copper-containing nitrite reductase, cytochrome P450 nitric oxide reductase, flavohemoglobin (Fhb), and formate/nitrite transporter homolog genes as possibly involved in fungal denitrification. Our results concerning the involvement of Fhb and formate/nitrite transporter perhaps provide new insight into the fungal denitrification system.
