RESEARCHERS at the Centre for Crop and Disease Management (CCDM) have developed new genetic resources with the aim of better understanding the damaging yellow spot fungal pathogen in Australian wheat crops.

Using yellow spot samples from Australia and overseas, they have sequenced the genomes – or complete DNA sets – of new fungal isolates, which is set to help researchers make new discoveries into the cause and impact of yellow spot disease (caused by the fungus Pyrenophora tritici-repentis), also known as tan spot.

Researchers at the Perth-based CCDM – a national research centre co-supported by Curtin University and the Grains Research and Development Corporation (GRDC) – sequenced DNA from yellow spot samples from Australia, the US and Canada, with the aim of improving the scientific resources available for studying this globally significant wheat pathogen.
