a universal pcr primer to detect members of the potyviridae and its use to examine the taxonomic status of several members of the family.a universal primer (sprimer: 5'-ggx aay aay agy ggx caz cc-3', x = a, g, c or t; y = t or c; z = a or g), designed from the consensus sequences that code for the conserved sequence gnnsgqp in the nib region of members of the family potyviridae, was used to amplify by rt-pcr the 3'-terminal genome regions from infected plant samples representing 21 different viruses in the family. sequencing of some of the fragments (c. 1.7 kb) showed that the type strain (attc pv-107) of oat necrotic mottle viru ...200111402861
characterisation of potyviruses from sugarcane and maize in china.sugarcane or maize leaves with mosaic virus symptoms were collected from 13 sites in china. sequence data showed that all 8 samples from maize contained sugarcane mosaic virus (scmv); complete sequences were determined from 2 samples and partial sequences (the ci coding region and the 3'-part of the genome) from the others. the 5 sugarcane samples all contained a virus tentatively described as sorghum mosaic virus (srmv) and in three of them scmv was also detected; 2 srmv sequences and the 3 scm ...200212111432
