tan spot resistance

Catalogue: Ground Cover
Genome sequencing of the pathogen that causes the wheat disease tan or yellow spot is expected to accelerate the release of more resistant varieties and improve resistance ratings for existing cultivars... The director of the Perth-based Australian Centre for Necrotrophic Fungal Pathogens (ACNFP), Professor Richard Oliver, says estimates that the disease causes annual losses of more than $200 million in Australian cropping might be conservative... Leader of tan spot research at ACNFP Dr Caroline Moffat says the new genome sequence means her team can focus on finding sequences for Australian isolates of the disease and genetic analysis of Australian wheat varieties...

Genome sequencing of the wheat disease tan (yellow) spot pathogen is expected to help researchers boost the productivity of the Australian wheat industry by tens of millions of dollars in coming years... Professor Oliver said the sequencing of the tan spot genome also followed the 2010 cloning and sequencing of the gene for tan spot necrosis 1 (Tsn1) - the protein produced by susceptible wheat cultivars, which helped tan spot and septoria (Stagonospora nodorum) infect the leaves... "Based on data in the 2009 GRDC report T he current and potential costs of diseases of wheat in Australia , I estimate that the sequencing of ToxA and Tsn1 will ultimately cut Australian crop losses caused by tan spot by about $100 million, while the PTR genome sequence should at least halve losses again," he said...
