Periodicity and gradients in dispersal of Alternaria linicola in linseed crops
Conidia of Alternaria linicola produced on infected linseed crops were mainly dispersed by wind. The numbers of conidia in the air above linseed crops collected by a Burkard spore sampler were greatest between 12:00 h and ...
Pseudorecombination and complementation between potato yellow mosaic geminivirus and tomato golden mosaic geminivirus
Pseudorecombinants made by exchanging the cloned, infectious genome components (DNAs A and B) of potato yellow mosaic geminivirus (PYMV) and the common strain (cs) of tomato golden mosaic geminivirus (csTGMV) are not ...
Effects of inoculum concentration, leaf age and wetness period on the development of dark leaf and pod spot (Alternaria brassicae) on oilseed rape (Brassica napus)
Experiments were done under controlled environment and glasshouse conditions to study the effects of inoculum concentration, leaf age and wetness period on the development of dark leaf and pod spot (Alternaria brassicae) ...
Early development of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape (Brassica napus) in relation to temperature and leaf wetness.
In controlled environment experiments to study early development of light leaf spot, lesions developed with leaf wetness durations of 16 to 48 h after inoculation of oilseed rape with conidial suspensions of Pyrenopeziza ...
Mutational analysis of potato yellow mosaic geminivirus
Mutations have been inserted into the virion and complementary sense ORFs encoding proteins with M(r)s in excess of 9 kDa of both DNA A and DNA B of potato yellow mosaic geminivirus (PYMV). Wild-type and mutant monomeric ...
Conformational studies of the beta-subunit of the high affinity IgE receptor : circular dichroism and molecular modelling
The receptor with high affinity for immunoglobulin E (Fc epsilon RI) on mast cells and basophils plays an important role in mediating many of the pathophysiological phenomena associated with allergy. Fc epsilon RI is a ...
