We have constructed pDESTR, a destination vector of gateway system especially for gene targeting and disruption in filamentous fungi. The vector was constructed by removing the multicloning site of pGEM-T easy vector, and inserting hygromycin phosphotransferase gene construct from pCB1004, and a gateway vector conversion cassette. In order to construct a DNA for gene disruption, only an inverse-polymerase chain reaction (PCR) amplification of the restricted, target sequence is needed. After the amplification with a 5′CACC-tagged primer and an ordinary primer, the DNA fragment will be inserted into pENTR/D-TOPO vector and then transferred into pDESTR through LR-recombination reaction. The resulting vector has the disruption construct, after being digested with the restriction enzyme used for the inverse-PCR. The effectiveness of this vector was assessed in Neurospora crassa. The use of pDESTR will therefore simplify the construction of a targeting vector, where multiple ligation steps are usually needed
