Research Abstract

I performed reidentification of the pathogenic fungi that is causing the tree cankers and diebacks on Guignardia dieback of Conifers, Guignardia canker of Poplar, Guignardia canker of Alder, Brown blight of Walnuts, Rough bark of Maples and Shoot blight of Japanese larch. As a result of sequence analysis and the observation on morphological characteristics, all isolates and all specimen which did test for this experiment were included in Botryosphaeria sp. However, Guignardia dieback of Conifers, Guignardia canker of Alder, Brown blight of Walnuts, and Rough bark of Maples were not identified, because result of the observation on morphological characteristics did not accord with sequence analysis.
