The project has focused on monitoring blackleg populations for virulence by exploiting markers for avirulence (Avr) genes in the fungus, which are complementary to resistance (Rlm) genes in the plant... Selection pressure acting on one avirulence gene can also influence other avirulence genes that are closely linked... Only two genes (LmCys2 and AvrLm6) have mutations in attacking isolates and are considered candidate genes...

Sclerotinia stem rot and blackleg are the two major disease constraints to canola production in Australia... After identifying the genes, they will be functionally analysed by mutation (or silencing) and their role in disease will be determined...

" Novel Approaches to control fungal diseases of oilseed Brassicas in Australia.. The major disease constraints to Australian canola production are blackleg caused by Leptosphaeria maculans, and stem rot caused by Sclerotinia sclerotiorum... The fungus comprised all isolates cultured from stubble of canola-quality juncea...

The mechanisms that the fungi use to infect plants are poorly understood... Genes in repetitive-rich regions can be lost and gained readily, which may account for the short period of time in which populations of the fungus overcome resistance conferred by single genes e.g. two years for sylvestris-derived resistance... Other genes identified by this approach include those encoding histones, thiolase, 'hypothetical' proteins, as well as proteins involved in cell wall structure and integrity...

The major grain legume grown in Australia is narrow-leafed lupins (NLL), but being a recently domesticated crop it has many agronomic limitations that have led to the dramatic fall of its use over the last few years... Our major focus is to decipher as much of the gene space sequence as possible and to use this valuable sequence information to greatly accelerate marker discovery and identification of candidate genes of interest for lupin crop improvement... Our approach has a heavy emphasis on molecular marker discovery and the development of a dense genetic map to help make the sequence information useful and lead to pre-breeding/breeding outcomes for the grains industry...

Ground Cover writer Dr Gio Braidotti explains the emerging science of genomics and the role it is starting to play in developing improved crop varieties By Dr Gio Braidotti The quest to understand the role the genome plays in determining the organism is moving from humans - where it was developed to understand disease - to species important for agriculture, including many crops... Genomics is still a fledgling science, but already possesses a range of techniques to scan and compare genomes in a population (plant or animal) to identify DNA-based difference that can account for variation in a trait of interest... Dr Gregor Durstewitz, who works for TraitGenerator, explained that genomic technology was established using species that contain just one type of genome (so-called 'diploid' organisms)...

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...
