MOLECULAR MECHANISMS INVOLVED IN THE PATHOGENESIS OF BEET SOIL-BORNE VIRUSES

A. Delbianco

Abstract


The genus Benyvirus includes the most important and widespread sugar beet viruses transmitted through the soil by the plasmodiophorid Polymyxa betae. Beet necrotic yellow vein virus (BNYVV) causes abnormal rootlet pro- liferation known as Rhizomania and has a worldwide dis- tribution, whereas Beet soil-borne mosaic virus (BSBMV) is present only in the USA. Sequence analysis has shown that these viruses have a similar genomic organization but are sufficiently different at the molecular level to be classified as separate species.
