Epidemiology of Leptosphaeria maculans in relation to forecasting stem canker severity on winter oilseed rape in the UK
In the UK, ascospores of Leptosphaeria maculans first infect leaves of oilseed rape in the autumn to cause phoma leaf spots, from which the fungus can grow to cause stem cankers in the spring. Yield losses due to early ...
Infection of linseed by Alternaria linicola : Effects of inoculum density, temperature, leaf wetness and light regime
Controlled environment studies were conducted to determine the effects of inoculum density, temperature, leaf wetness and light regime on the infection of linseed by Alternaria linicola. The % cotyledons and leaves with ...
Development of PCR based diagnostic techniques for the two mating types of Pyrenopeziza brassicae (light leaf spot) on winter oilseed rape (Brassica napus ssp. oleifera)
Two sets of PCR primers were designed from DNA sequence which flanked the 3' end of the Pyrenopeziza brassicae mating type idiomorphs (MAT-1 and MAT-2). The first set of primers facilitated the amplification of a 750 bp ...
Ascospores as primary inoculum for epidemics of white leaf spot (Mycosphaerella capsellae) in winter oilseed rape in the UK
In the UK, conidia of Pseudocercosporella capsellae, the anamorph of Mycosphaerella capsellae, were observed on white leaf spot lesions on leaves throughout the growing season. Ascomata were not observed on lesions on ...
Meloidogyne incognita surface antigen epitopes in infected Arabidopsis roots
Surface-coat epitopes of Meloidogyne incognita were detected in root tissues of Arabidopsis thaliana during migration and feeding site formation. A whole-mount root technique was used for immunolocalization of surface coat ...
Implications of land use change for the production of plant biomass in densely populated Sahelo-Sudanian shrub-grasslands in north-east Nigeria.
The production of plant biomass on small farms and in woodland in densely populated locations in the Nigerian Sahelo-Sudan is estimated in order to test the hypothesis that conversion of land from natural vegetation to ...
Suicide among drug addicts in the UK
The extent of suicide among addicts in the UK has not been sufficiently examined.
Methods for assessment of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape (Brassica napus) in the UK
Light leaf spot (Pyrenopeziza brassicae) was assessed as % plants with light leaf spot, % leaves with light leaf spot or % leaf area with light leaf spot in winter oilseed rape field experiments done at different sites ...
Differential release of dopamine by nitric oxide in subregions of rat caudate putamen slices
Fast cyclic voltammetry was used to measure NO and dopamine (DA) simultaneously in rat caudate putamen (CPu) slices. Analysis of electrochemical signals obtained from mixtures of DA and NO showed that subtraction of either ...
Diagnosis of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape (Brassica napus) in the UK
Light leaf spot lesions were generally first observed as light green areas on leaves of UK winter oilseed rape crops in January or February and later became brittle and bleached. Elongated lesions, which were brown with ...
