| soybean cyst nematode culture collections and field populations from north carolina and missouri reveal high incidences of infection by viruses. | five viruses were previously discovered infecting soybean cyst nematodes (scn; heterodera glycines) from greenhouse cultures maintained in illinois. in this study, the five viruses [scnv, scpv, scrv, sctv, and sbcnv-5] were detected within scn greenhouse and field populations from north carolina (nc) and missouri (mo). the prevalence and titers of viruses in scn from 43 greenhouse cultures and 25 field populations were analyzed using qrt-pcr. viral titers within scn greenhouse cultures were simi ... | 2017 | 28141854 |
