We have developed phosphate permease gene sequence-based PCR detection system of Fusarium cerealis phytopathogenic fungus. Sequencing and analysis revealed that the gene displayed unique polymorphism and could serve to establish phylogenetic relations as well as a marker to design specific primers. The specificity assay has confirmed the absence of cross reactions with DNAs of closely related Fusarium species. The qPCR assay demonstrated the 10 pg detection limit of specific DNA per reaction.
