MOLECULAR CHARACTERIZATION AND MATING STUDY OF Fusarium proliferatum FROM VARIOUS HOSTS IN MALAYSIA

Fusarium proliferatum is a well-known plant pathogenic fungus-infected many crops. The present study was carried out to molecularly identified and characterized morphologically F. from various hosts substrates. species identity of the isolates verified as based on TEF-1α sequences phylogenetic analysis indicated high intraspecific variations. RFLP-IGS also variations which were clustered into three RFLP Groups (I, II, III) comprising 67 IGS haplotypes. Seventy crossed-fertile proven be members mating population D (MP-D) Gibberella fujikuroi while four infertile. A level vital for adaptation survival in host environment. Correct identification important fungus pathogen mycotoxin producer. essential strategize suitable disease control methods well predict their range production.
