Beet Necrotic Yellow Vein Virus (BNYVV) was detected by enzyme-linked immunosorbent assay (ELISA) and RNA/DNA dot hybridization using either radiolabelled or non-radioactive probes. Dot hybridization specifically distinguished isolates that could not be distinguished by ELISA. The detection thresholds for ELISA, hybridization with non-radioactive probes and hybridization with radiolabelled probes were 2 ng, 0.2 ng, 0.02 ng of purified virus, respectively. Dot hybridization with non-radioactive probes could be performed on crude infected beet root extracts, thus providing a useful tool for monitoring BNYVV infection and for routine testing in plant breeding programs.
通过酶联免疫吸附测定(ELISA)以及使用放射性标记或非放射性探针的RNA/DNA斑点杂交来检测甜菜坏死黄脉病毒(BNYVV)。斑点杂交能够特异性地区分ELISA无法区分的分离株。ELISA、与非放射性探针杂交以及与放射性标记探针杂交的检测阈值分别为2纳克、0.2纳克、0.02纳克纯化病毒。与非放射性探针的斑点杂交可在感染的甜菜根粗提物上进行,从而为监测BNYVV感染以及植物育种计划中的常规检测提供了一种有用的工具。
