Subject: Furovirus-infection of rye discovered for the first time in North America
Publicada: July 10, 2001
Source: American Phytopathological Society, PLANT DISEASE
During winter and spring 2000, a dwarf recurrent population (99RP17) of rye, Secale cereale, was found to be infected with a Furovirus at the North Florida Research and Education Center in Quincy, Gadsden County, FL. This represents the first report of a Furovirus infecting field-grown rye in North America. Based on disease symptoms, as well as enzyme-linked immusorbent assays performed by Agdia Inc. (Elkhart, IN), and an association with cystosori of Polymyxa graminis, this virus seems to be soilborne wheat mosaic virus (SBWMV). However, the possibility that it may be soilborne rye mosaic virus (SBRMV) has yet to be explored using nucleotide sequence analysis. Based on genome analyses, SBRMV is likely to be a new species of the genus Furovirus. It was reported from Germany in 1998 and from New Zealand in 1999.
