Abstract:
The mitochondrial intermediate peptidase (MIP) gene is conserved in fungi. It is linked closely with the mating-type A (mtA) gene. In this study, a fragment of the MIP gene in Volvariella volvacea (Bull. ex Fr.) Singer was first cloned by homologue-based cloning technology. Subsequently, the entire MIP DNA sequence (PYd21-MIP) was obtained after the fragment was compared with the genomic data through BLAST analysis. The PYd21-MIP sequence appeared to be homologous with the MIP gene in other fungi. Phylogenetic analysis of PYd21-MIP and other MIP sequences from diverse fungi agreed with the current organism phylogeny. Analysis of protein domains by InterProScan software and motif searching demonstrated that PYd21-MIP encodes a homologous MIP protein. These data support the hypothesis that the PYd21-MIP protein is a Hog-MIP protein homologue from V. volvacea.
