A breakthrough achieved by Western Australian scientists will speed up the delivery of new wheat varieties with resistance to yellow spot - arguably the country's most costly wheat disease... Dr Moffat and her team removed the ToxA gene via a process in which it was replaced with another gene - a world-first achievement for yellow spot... "Our achievement paves the way for removing other yellow spot genes of interest and allows us to study different toxins produced by the fungus...

Continued vigilance urged on yellow spot disease.. "Yellow spot was found in varieties such as Mace , Magenta and Wyalkatchem , which indicates that even putatively-resistant varieties can be susceptible to the disease," she said... Dr See said it was still recommended that growers chose varieties 'insensitive' to ToxA such as Mace , Magenta and Wyalkatchem as ToxA was the most potent of the identified effectors...

Department of Agriculture and Food WA (DAFWA) scientists have identified the material in collaboration with researchers from The University of Adelaide and Victoria's Department of Primary Industries under a Grains Research and Development Corporation (GRDC) funded project... "Since starting work on this GRDC funded 'pre-breeding' project in 2010, our research team has found five 'chromosomal regions' - or genes other than tsn1 - which confer resistance to yellow spot," Dr Shankar said... Dr Shankar said the research had also identified novel yellow spot resistant germplasm among lines imported from the International Centre for Agricultural Research in Dry Areas (ICARDA) and the International Maize and Wheat Improvement Centre (CIMMYT), through the CIMMYT-Australia-ICARDA Germplasm Evaluation (CAIGE) project...
