FIELD: biotechnology, genetics.
SUBSTANCE: invention relates to methods used for detecting low frequency mutations occurrence in gene encoding cytochrome b. Method involves isolation of DNA from known fungi for constructing oligonucleotide probe or primer. Then polymerase chain reaction (PCR) is carried out for assay of binding the nucleotide probe with amplicon generated by this reaction, or the presence of amplicon is detected that is generated as result of PCR using indicated primers. Invention provides rapid and precise detection of mutations conferring resistance of fungus against fungicide.
EFFECT: improved diagnostic methods for detecting mutations.
