Abstract
AbstractSix monoclonal antibodies (MAbs) against a French isolate of barley yellow mosaic virus (BaYMV) pathotype 2 were produced and their isotypes determined. These MAbs were compared in ELISA for their reactivity with different isolates of BaYMV, wheat yellow mosaic virus (WYMV), wheat spindle streak mosaic virus (WSSMV) and oat mosaic virus (OMV).The six MAbs detected BaYMV in TAS ELISA and western blot, whereas in ACP ELISA no reaction was observed with isolates of BaYMV and WYMV. These MAbs could recognize the sequential motifs situated at the surface of viral particles. The six MAbs detected all the European isolates of BaYMV pathotype 1 and 2 and the Japanese isolate of this viral pathotype 1–1. In contrast to other MAbs, MAb IV did not react with the Japanese isolate of BaYMV pathotype II‐l. In TAS ELISA. MAbs I, II, III, and IV detected the Japanese isolate of WYMV and American isolates of WSSMV only when they were captured by anti‐WYMV polyclonal antibodies, A French isolate of OMV was detected only by the MAbs I and II in TAS ELISA with Polyclonal anti‐BaYMV.
