Abstract

The invention discloses methods which are particularly sensitive for detecting low frequencies of mutations in mitochondrially encoded genes, such as the cytochrome b gene, making these an especially useful and commercially important way of screening plant pathogenic fungi for the onset of fungicidal resistance wherein the resistance is due to a mutation in a mitochondrially encoded gene. The methods disclosed include single nucleotide polymorphism detection techniques especially PCR detection methods. Also disclosed are DNA sequences encoding part of the wild type and mutant cytochrome b sequences of a range of plant pathogenic fungi and the use of the sequence information to detect mutations giving rise to fungicidal resistance. Allele specific oligonucleotides and oligonucleotide probes, diagnostic primers and diagnostic kits are also disclosed.
