identifying genetic diversity of avirulence genes in leptosphaeria maculans using whole genome sequencing.next generation sequencing technology allows rapid re-sequencing of individuals, as well as the discovery of single nucleotide polymorphisms (snps), for genomic diversity and evolutionary analyses. by sequencing two isolates of the fungal plant pathogen leptosphaeria maculans, the causal agent of blackleg disease in brassica crops, we have generated a resource of over 76 million sequence reads aligned to the reference genome. we identified over 21,000 snps with an overall snp frequency of one sn ...201323793572
occurrence of a new subclade of leptosphaeria biglobosa in western australia.stem canker of crucifers is caused by an ascomycete species complex comprising of two main species, leptosphaeria maculans and l. biglobosa. these are composed of at least seven distinct subclades based on biochemical data or on sequences of internal transcribed spacer (its), the mating type mat1-2 or fragments of actin or beta-tubulin genes. in the course of a wide-scale characterization of the race structure of l. maculans from western australia, a few isolates from two locations failed to amp ...200818944083
recurring challenges from a necrotrophic fungal plant pathogen: a case study with leptosphaeria maculans (causal agent of blackleg disease in brassicas) in western australia.blackleg disease of brassica napus, caused by the necrotrophic fungus leptosphaeria maculans, causes severe yield losses in australia, europe and canada. in western australia, it nearly destroyed the oilseed rape industry in 1972 when host genotypes and conducive environmental conditions favoured severe epidemics. the introduction of cultivars with polygenic resistance and the adoption of sound cultural practices two decades later helped to manage the disease. these were abandoned by many farmer ...200515994842
temporal patterns of ascospore release in leptosphaeria maculans vary depending on geographic region and time of observation.diurnal patterns of spore release have been observed in a number of fungal pathogens that undergo wind-assisted dispersal. the mechanisms that drive these patterns, while not well understood, are thought to relate to the ability of dispersing spores to survive their journey and infect new hosts. in this paper, we characterise the diurnal pattern of ascospore release by a western australian population of leptosphaeria maculans. although l. maculans has been previously shown to exhibit diurnal pat ...201223271454
