Analysis of the mating-type loci of co-occurring and phylogenetically related species of Ascochyta and Phoma.
Ascochyta and Phoma are fungal genera containing several important plant pathogenic species. These genera are morphologically similar, and recent molecular studies performed to unravel their phylogeny have resulted in the establishment of several new genera within the newly erected Didymellaceae family. An analysis of the structure of fungal mating-type genes can contribute to a better understa...
متن کاملAssessment of Selected Pea Genotypes Reaction to Ascochyta Blight under Field Conditions and the Impact of Disease Severity on Yield Components
The response of pea (Pisum sativum) genotypes to ascochyta blight disease and the effect of disease severity on yield components were evaluated in a 4-year trial under field conditions. Peas were inoculated with Ascochyta pinodes, the anamorph of Mycosphaerella pinodes, or with Phoma pinodella separately and with a mixture of both species. Mean infection ratings of all inoculation treatments we...
متن کاملA single, plastic population of Mycosphaerella pinodes causes ascochyta blight on winter and spring peas (Pisum sativum) in France.
Plant diseases are caused by pathogen populations continuously subjected to evolutionary forces (genetic flow, selection, and recombination). Ascochyta blight, caused by Mycosphaerella pinodes, is one of the most damaging necrotrophic pathogens of field peas worldwide. In France, both winter and spring peas are cultivated. Although these crops overlap by about 4 months (March to June), primary ...
متن کاملStudies on the Control of Ascochyta Blight in Field Peas (Pisum sativum L.) Caused by Ascochyta pinodes in Zhejiang Province, China
Ascochyta blight, an infection caused by a complex of Ascochyta pinodes, Ascochyta pinodella, Ascochyta pisi, and/or Phoma koolunga, is a destructive disease in many field peas (Pisum sativum L.)-growing regions, and it causes significant losses in grain yield. To understand the composition of fungi associated with this disease in Zhejiang Province, China, a total of 65 single-pycnidiospore fun...
متن کاملVirulence and Genetic Variability Among Isolates of Mycosphaerella pinodes
Mycosphaerella blight, caused by Mycosphaerella pinodes (Berk. & Bloxam) Vestergr., is the most important foliar disease of field pea (Pisum sativum L.) worldwide (2,7,16,17,23,30,31). In Canada, average dry seed yield losses caused by this disease have been estimated at 10%, and losses of over 50% have been reported in field trials (28,34). Management for Mycosphaerella blight is limited to fu...
