Analysing virulent and avirulent Leptosphaeria maculans isolates to understand R gene-mediated resistance in Brassica napus
Mitrousia, Georgia; Huang, Yongju; Hall, Avice; Fitt, Bruce D.L. (2012-10)Phoma stem canker (Leptosphaeria maculans) is a major disease on oilseed rape (Brassica napus) in Europe (e.g. it causes losses to UK farmers of > £100M p.a.). Single major gene resistance (R) in B. napus against L. maculans ... -
Combining R gene and quantitative resistance increases effectiveness of cultivar resistance against Leptosphaeria maculans in Brassica napus in different environments : Combining R gene and quantitative resistance against Leptosphaeria maculans
Huang, Yongju; Mitrousia, Georgia; Mohamed Sidique, Siti; Qi, Aiming; Fitt, Bruce (2018-05-23)Using cultivar resistance against pathogens is one of the most economical and environmentally friendly methods for control of crop diseases. However, cultivar resistance can be easily rendered ineffective due to changes ... -
Comparative epidemiology of Leptosphaeria maculans and L. biglobosa on oilseed rape in the UK
Huang, Yongju; Mitrousia, Georgia; Sidique, Siti Nordahliawate; Fitt, Bruce D.L. (2013-08)Phoma stem canker is a major disease problem on winter oilseed rape (Brassica napus) in the UK. The disease is caused by two closely related species, Leptosphaeria maculans and L. biglobosa. Previous epidemiology work has ... -
Effectiveness of Rlm7 resistance against Leptosphaeria maculans (phoma stem canker) in UK winter oilseed rape cultivars
Mitrousia, Georgia; Huang, Yongju; Qi, Aiming; Mohamed Sidique, Siti; Fitt, Bruce (2018-08)The Rlm7 gene in Brassica napus is an important source of resistance for control of phoma stem canker on oilseed rape caused by the fungus Leptosphaeria maculans. This study shows the first report of L. maculans isolates ... -
Effector-triggered defence against apoplastic fungal pathogens
Stotz, Henrik; Mitrousia, Georgia; de Wit, Pierre; Fitt, Bruce D.L. (2014-08-01)R gene-mediated host resistance against apoplastic fungal pathogens is not adequately explained by the terms pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) or effector-triggered immunity (ETI). ... -
Geographic variation in Leptosphaeria maculans (phoma stem canker of oilseed rape) populations in the UK
Huang, Yongju; Mitrousia, Georgia; Fitt, Bruce D.L. (2013-08)Major resistance (R) gene-mediated resistance against Leptosphaeria maculans is associated with a gene-forgene interaction in which the product of a pathogen effector (Avr) gene is recognised by the product of a host R ... -
Pathogenicity of Leptosphaeria biglobosa to oilseed rape (Brassica napus) cultivars differing in resistance against Leptosphaeria maculans
Mitrousia, Georgia; Huang, Yongju; Hall, Avice; Fitt, Bruce D.L. (2013-08)Field and controlled environment experiments were done to examine the pathogenicity of L. biglobosa on cultivars with good resistance (carrying the Rlm7 gene) or moderate resistance (carrying the Rlm4 gene) against L. ... -
Pathogenicity of leptosphaeria maculans isolates obtained from brassica napus (oilseed rape) cultivars with the rlm7 resistance gene
Mitrousia, Georgia; Huang, Yongju; Hall, Avice; Fitt, Bruce D.L. (2013-08)Isolates obtained from winter oilseed rape cultivars with the resistance gene Rlm7 were examined for their pathogenicity by inoculation onto cotyledons and true leaves of the susceptible cultivar Drakkar (no R gene) and ... -
The race structure of Leptosphaeria maculans (phoma stem canker) in the United Kingdom
Huang, Yongju; Mitrousia, Georgia; Fitt, Bruce D.L. (INRAE, 2012-10)Phoma stem canker (Leptosphaeria maculans) is the main disease problem on winter oilseed rape (Brassica napus) in the UK, causing losses of > £100M p.a., despite use of fungicides. Two types of resistance to L. maculans ... -
Severity of phoma leaf spotting and stem canker on Brassica napus cultivars with Rlm7 resistance against Leptosphaeria maculans in the UK
Mitrousia, Georgia; Huang, Yongju; Hall, Avice; Fitt, Bruce D.L. (2012) -
Temperature affects the effectiveness of R gene mediated resistance against Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape)
Huang, Yongju; de Lope, Lucia; Mitrousia, Georgia; Stotz, Henrik; Larkan, Nicholas J.; Rimmer, Roger S.; Fitt, Bruce D.L. (2014)Phoma stem canker (Leptosphaeria maculans) is an economically important disease on oilseed rape (Brassica napus) in Europe, Australia and North America. Effective control of this disease relies on the use of two types of ... -
Understanding interactions between quantitative resistance and qualitative resistance for sustainable management of Phoma stem canker (Leptosphaeria maculans ) in oilseed rape (Brassica napus)
Huang, Yongju; Mitrousia, Georgia; Fitt, Bruce D.L. (2013-08)Effective control of phoma stem canker (Leptosphaeria maculans) relies on use of host resistance. Two types of resistance to L. maculans have been identified; major resistance (R) gene-mediated qualitative resistance and ...
