Soil-borne cereal mosaic virus (SBCMV) was reported to affect wheat crops in Italy in 1960. Subsequently in many other European countries too. SBCMV causes a serious disease of wheat and growing resistant varieties represents the only economical means of control. Several wheat samples showing typical Furovirus symptoms were collected in Italy during the 2003 and 2004 seasons. Molecular characterization of the viral coat protein gene was carried out to study the degree of genetic diversity of these viruses over a relatively wide geographic area. Sequence data analysis revealed a high degree of genetic identity among Italian isolates, and between Italian and others SBCMV accessions. Alignment of deduced CP amino acids sequences showed an homology close to 100% between European isolates. Our results confirm a low degree of genetic diversity between European Furoviruses infecting wheat.

Abstract
Soil-borne cereal mosaic virus (SBCMV) was reported to affect wheat crops in Italy in 1960. Subsequently in many other European countries too. SBCMV causes a serious disease of wheat and growing resistant varieties represents the only economical means of control. Several wheat samples showing typical Furovirus symptoms were collected in Italy during the 2003 and 2004 seasons. Molecular characterization of the viral coat protein gene was carried out to study the degree of genetic diversity of these viruses over a relatively wide geographic area. Sequence data analysis revealed a high degree of genetic identity among Italian isolates, and between Italian and others SBCMV accessions. Alignment of deduced CP amino acids sequences showed an homology close to 100% between European isolates. Our results confirm a low degree of genetic diversity between European Furoviruses infecting wheat.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
