Abstract: (7038 Views)
A survey was carried out in five provinces of Iran (Kerman, Sistan and Baluchestan, Hormozgan, Khorasan and Yazd) for the presence of Alfalfa mosaic virus (AMV) sero-types in alfalfa during 2002 to 2003. The number of samples collected was 250, represent-ing the diversity and geographical distribution of AMV in these areas. Diagnosis was car-ried out using polyclonal (PAbs) and monoclonal (MAbs) antibodies. A total of 110 symp-tomatic leaf samples gave a positive reaction in ELISA with polyclonal antibodies. Twelve out of 20 MAbs reacted with all samples tested and were considered as non-differentiating MAbs. Only the MAbs-12, 13, 15, 21, 22 and 24 gave a clear differential reaction and were used for identifying AMV serotypes. Two MAbs (1 and 2) did not react with AMV posi-tive samples. Serological relatedness among AMV samples was studied by indicating the existence of six serotypes of AMV strains in the surveyed areas.
