Furovirus-infection of rye discovered for the first time in North America

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.
