Comparison of ITS sequences from UK and North American sugar-beet powdery mildews and the designation of Erysiphe betae.
Powdery mildew of sugar beet, a disease of major economic significance, was first described at the beginning of the 20th century, and since then there has been some confusion over the correct taxonomic identity of the causal agent. In Europe, the fungus was initially classified as the novel species Microsphaera betae, later re-named Erysiphe betae, whilst in America it was identified as E. poly...

متن کاملFish-isolated Naegleria strains and their phylogeny inferred from ITS and SSU rDNA sequences.
Effort was made to identify Naegleria strains isolated from organs of fish, using phylogenetic analyses of SSU rDNA and ITS sequences. Eighteen fish-isolated strains studied enlarged substantially the so far available set of Naegleria strains characterized by both molecular markers. The phylogenetic analyses of separate and concatenated SSU rDNA and ITS sequences revealed phylogenetic relations...
متن کاملCorrection: Characterization of Glomerella Strains Recovered from Anthracnose Lesions on Common Bean Plants in Brazil
Anthracnose caused by Colletotrichum lindemuthianum is an important disease of common bean, resulting in major economic losses worldwide. Genetic diversity of the C. lindemuthianum population contributes to its ability to adapt rapidly to new sources of host resistance. The origin of this diversity is unknown, but sexual recombination, via the Glomerella teleomorph, is one possibility. This stu...
