| grapevine leafroll-associated virus 1 occurs as genetically diverse populations. | the genetic diversity of thirty-four isolates of grapevine leafroll-associated virus 1 (glrav-1) from different wine, table and ornamental grape cultivars in california, new york and washington states in the u.s.a. was investigated. segments of the heat-shock protein 70 homolog (hsp70h) gene, coat protein (cp) gene, coat protein duplicate 2 (cpd2) gene and orf9 (p24) were amplified by rt-pcr, cloned and sequenced. a pairwise comparison of nucleotide sequences revealed intra- and inter-isolate se ... | 2011 | 21830956 |
