AI Article Synopsis
- The phylogeny and taxonomy of certain species were studied by examining collections from Asia, Europe, and North America and analyzing their partial rDNA nucleotide sequences.
- The analysis confirmed that the species in question are distinct despite their similar morphology, establishing them as two separate entities.
- Additionally, a notable genetic difference was found in the 28S rRNA gene, reinforcing the conclusion that hop powdery mildew and its counterpart should be classified as separate species.
Article Abstract
The phylogeny and taxonomy of (including , syn. nov.) have been examined. Asian, European and North American collections were examined and the nucleotides sequences of their partial rDNA region were determined. In particular, the relationship between and was analysed. The results confirmed and as two separate, morphologically similar species. The phylogenetic analysis revealed a similar phylogeny to that of the host genera. Although ITS sequences retrieved from Asian, European and North American specimens of on various spp. are identical to sequences from on hop, there is consistently one base substitution at the 5'-end of 28S rRNA gene between the species. This result provides evidence that the hop powdery mildew and are biologically and morphologically clearly distinguished, and should be maintained as two separate species.
