| three genetic grapevine leafroll-associated virus 3 variants identified from south african vineyards show high variability in their 5'utr. | three genetic variants of grapevine leafroll-associated virus 3 (glrav-3) were identified in vineyards of the western cape, south africa. the glrav-3 variants were identified by single-strand conformation polymorphism (sscp) profiles generated from a region amplified in orf5. orf5 sequence data confirmed the three genetic variant groups, and a specific sscp profile was assigned to each variant group. the results of sscp analysis of this region in orf5 showed that this method gives a fast and rel ... | 2010 | 20830600 |
