Does a polyphasic approach assign the pathogenic Erwinia strains from diseased pear trees in Japan to Erwinia pyrifoliae?
Erwinia pyrifoliae strains from Korea and the pear pathogenic Erwinia strains from Japan belong taxonomically into the same species, but show slight divergences in nucleotide sequences used for classification. The allocation is not only supported by microbiological properties, but also by a host range restricted to pear observed before by others.
The cDNA previously identified by Robinson et al as zebrafish ultraviolet opsin is not a cone opsin but is likely to be a rod opsin.
