A 531 bp fragment of a putative mitochondrial intermediate peptidase (mip) gene from Lentinula edodes was amplified by PCR using a pair of degenerate primers designed according to conserved sequences of mip genes reported in other Basidiomycetes. Alignment analysis revealed that this putative partial mip gene from L. edodes exhibited high homology with corresponding segments of mip genes from the other Basidiomycetes. Since the gene encoding MIP appears to be very closely linked with the A type mating gene of Basidiomycetes, identification of mip may prove a useful tool for locating and cloning the A type mating gene in L. edodes and other edible fungi.
