| genome diversity and intra- and interspecies recombination events in grapevine fanleaf virus. | abstract grapevine fanleaf virus (gflv) was documented in self-rooted vines of four grapevine (vitis vinifera) cultivars in eastern washington. gflv was found as mixed infection in cvs. pinot noir, chardonnay, and cabernet franc and as single infections in cv. merlot. fanleaf disease symptoms were only observed in the first two cultivars. the spatial distribution of gflv-infected grapevines was random, suggesting primary spread through planting virus-infected cuttings rather than infield transmi ... | 2009 | 19900006 |
| genetic diversity of grapevine virus a in washington and california vineyards. | grapevine virus a (gva; genus vitivirus, family betaflexiviridae) has been implicated with the kober stem grooving disorder of the rugose wood disease complex. in this study, 26 isolates of gva recovered from wine grape (vitis vinifera) cultivars from california and washington were analyzed for their genetic diversity. an analysis of a portion of the rna-dependent rna polymerase (rdrp) and complete coat protein (cp) sequences revealed intra- and inter-isolate sequence diversity. our results indi ... | 2014 | 24168043 |
| complete genome sequence analysis of an american isolate of grapevine virus e. | the complete genome sequence of grapevine virus e (gve) collected from a red-berried wine grape cultivar (cabernet sauvignon) in washington state was determined. the 7,568 nucleotide long genome of gve is more similar in sequence identity with a gve isolate from a wine grape cv. shiraz from south africa when compared with an isolate from "aki queen" grape from japan. like gve isolates from south africa and japan, the washington isolate encodes five open reading frames (orfs) and the overall geno ... | 2013 | 23296875 |
| beneficial insects attracted to native flowering buckwheats (eriogonum michx) in central washington. | native plant and beneficial insect associations are relatively unstudied yet are important in native habitat restoration programs aimed at improving conservation biological control in perennial crops such as wine grapes. beneficial insects (predators, parasitoids, pollinators) attracted to 10 species of flowering native wild buckwheat (eriogonum spp.) in central washington were identified and counted on transparent sticky traps. combining all categories of beneficial insects, the mean number per ... | 2014 | 24960157 |
