Understanding interactions between quantitative resistance and qualitative resistance for sustainable management of Phoma stem canker (Leptosphaeria maculans ) in oilseed rape (Brassica napus)
(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 ...
Evidence for presence of the founder Ia mtDNA haplotype of Phytophthora infestans in 19th century potato tubers from the Rothamsted archives
(2013-06)
Late blight remained a significant disease for potato growers in Europe long after the famine of the 1840s. Of the four mitochondrial haplotypes of Phytophthora infestans, only the Ia mitochondrial DNA (mtDNA) haplotype ...
Assessment of Risk of Establishment of Wheat Dwarf Bunt (Tilletia controversa) in China
(2013-01)
Wheat dwarf bunt, caused by Tilletia controversa Kühn (TCK), is an important quarantine wheat disease throughout the world. Based on published research results of the biology and the epidemiology of the disease, the main ...
The role of chasmothecia in the initiation of epidemics
(Association of Applied Biologists, 2013)
Evolutionary relationships between Rhynchosporium lolii sp. nov. and other Rhynchosporium species on grass.
(2013)
The fungal genus Rhynchosporium (causative agent of leaf blotch) contains several host-specialised species, including R. commune (colonising barley and brome-grass), R. agropyri (couch-grass), R. secalis (rye and triticale) ...
Analysing virulent and avirulent Leptosphaeria maculans isolates to understand R gene-mediated resistance in Brassica napus
(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 ...
The race structure of Leptosphaeria maculans (phoma stem canker) in the United Kingdom
(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 ...
Effects of R gene-mediated resistance in Brassica napus (oilseed rape) on asexual and sexual sporulation of Pyrenopeziza brassicae (light leaf spot)
(2012-05-09)
The phenotype of the R gene-mediated resistance derived from oilseed rape (Brassica napus) cv. Imola against the light leaf spot plant pathogen, Pyrenopeziza brassicae, was caracterized. Using a doubled haploid B. napus ...
Comparative biology of different plant pathogens to estimate effects of climate change on crop diseases in Europe
(2012-05)
This review describes environmental factors that influence severity of crop disease epidemics, especially in the UK and north-west Europe, in order to assess the effects of climate change on crop growth and yield and ...
Role of inoculum sources in Rhynchosporium population dynamics and epidemics on barley.
(HGCA, 2012-04)
Rhynchosporium leaf blotch of barley, caused by the fungus Rhynchosporium secalis, is of increasing importance in world agriculture. It is the most serious disease of winter and spring barley in the UK, causing substantial ...
