Mycosphaerella is polyphyletic
Mycosphaerella, one of the largest genera of ascomycetes, encompasses several thousand species and has anamorphs residing in more than 30 form genera. Although previous phylogenetic studies based on the ITS rDNA locus supported the monophyly of the genus, DNA sequence data derived from the LSU gene distinguish several clades and families in what has hitherto been considered to represent the Myc...
متن کاملMycosphaerella leaf spot diseases
By the end of the 1980s, black leaf streak disease caused by Mycosphaerella fijiensis was present in all continents where bananas or plantains were grown, although distribution in some regions was limited to a few countries. In this presentation, the spread of the disease during the 1990s in several countries and regions, and the important socio-economic consequences are discussed. From 1990 to...
متن کاملAdditions to the Mycosphaerella complex
Species in the present study were compared based on their morphology, growth characteristics in culture, and DNA sequences of the nuclear ribosomal RNA gene operon (including ITS1, ITS2, 5.8S nrDNA and the first 900 bp of the 28S nrDNA) for all species and partial actin and translation elongation factor 1-alpha gene sequences for Cladosporium species. New species of Mycosphaerella (Mycosphaerel...
متن کاملEpidemiology / Épidémiologie Temporal and spatial dynamics of mycosphaerella blight [Mycosphaerella pinodes] in field pea
The temporal and spatial patterns of epidemics of mycosphaerella blight, [Mycosphaerella pinodes] in field pea in western Canada were characterized during 2000 and 2001, using mathematical models and geostatistical analysis. The logistic model well described the disease progress over distances and in various directions from the inoculum source. The temporal disease progress rates measured by th...
متن کاملDaily and seasonal spore dispersal by Mycosphaerella pinodes and development of mycosphaerella blight of field pea
Daily and seasonal spore dispersal of Mycosphaerella pinodes (Berk & Bloxam) Vestergren and the relationship of spore dispersal to distance and disease severity were investigated in a pea field in western Canada during two consecutive years. Most ascospores were released in response to rain events, during the first 23–27 d after the inoculum source area was infested with naturally diseased pea ...
