|a Sharka disease, caused by Plum pox virus (PPV), is probably the most important disease of stone fruits crops worldwide because of tremendous yield losses from infected trees (1). During November 2004, symptoms resembling sharka disease were observed in a plum and apricot orchard consisting of 5,000 trees in Pocito, San Juan Province, Argentina. Apricot leaves showed chlorotic spots while plum leaves showed chlorotic rings, spots, and irregular edges. Plum fruits were deformed and much smaller than those from symptomless trees. Samples collected from 70 symptomatic trees were tested using double-antibody sandwich enzyme-linked immunosorbent assays with a polyclonal antiserum anti-PPV from BIOREBA (Reinach BL1, Switzerland), and immunosorbent electron microscopy with a polyclonal antiserum from our laboratory made against a recombinant PPV capsid protein (CP). The samples were also tested using double-antibody sandwich indirect enzyme-linked immunosorbent assay using the REAL kit (Durviz, Valencia, Spain) with two different monoclonal antibodies including Mab 5b that recognizes all strains of PPV and Mab 4DG5 that is specific for PPV strain D. Samples were positive with both antibodies in 80% of the cases. Leaf extracts from symptomatic plum samples were also analyzed by immuno-capture reverse-transcription polymerase chain reaction. A 1,209-bp fragment was amplified with specific primers that anneal at the 5' end of the coat protein coding region and the viral 3' end poly A tail. The amplified fragment was cloned and the nucleotide sequence was determined for two of the resulting clones (Gen-Bank Accession Nos. DQ299537 and DQ299538). The sequences were 98% identical with the PPV-strain D from the United States (GenBank Accession No. AF360579) and Germany (GenBank Accession No. X81081). The restriction sites for AluI and RsaI, previously described (2) as typical for the PPV-D strain, were present in the expected positions. To our knowledge, this is the first report of PPV-D in Argentina. Reference: (1) M. Németh. Virus, Mycoplasma, and Rickettsia Disease of Fruit Trees.
