Epidemiology / Épidémiologie Prevalence of pathogenicity groups of Leptosphaeria maculans in western Canada and North Dakota, USA
Blackleg, caused by Leptosphaeria maculans, is an economically important disease of canola (Brassica napus). Little is known about the current distribution of pathogenicity groups (PGs) of L. maculans in Canada and the United States. Four hundred and eighty-nine isolates of L. maculans or Leptosphaeria biglobosa from western Canada and North Dakota, United States, were placed in five PGs (PG-1 ...
متن کاملThe LmSNF1 Gene Is Required for Pathogenicity in the Canola Blackleg Pathogen Leptosphaeria maculans
Leptosphaeria maculans is a fungal pathogen causing blackleg in canola. Its virulence has been attributed, among other factors, to the activity of hydrolytic cell wall degrading enzymes (CWDEs). Studies on the pathogenicity function of CWDEs in plant pathogenic fungi have been difficult due to gene redundancy. In microorganisms many CWDE genes are repressed by glucose and derepressed by the fun...
متن کاملEffects of Leptosphaeria maculans race structure and fitness cost of virulence on management of phoma stem canker in oilseed rape
Fitness of virulent (avrLm1 and avrLm4) or avirulent (AvrLm1 and AvrLm4) isolates of Leptosphaeria maculans on Brassica napus without the corresponding resistance genes Rlm1 and Rlm4 was investigated in controlled environment (CE) and field experiments. Results indicate that there is a measurable fitness cost for virulent isolates compared to avirulent isolates in terms of number of lesions, si...
