dc.description.abstractIn 1996, plants of the terrestrial orchid Phaius tankervilliae from a nursery in the Central Valley of Costa Rica were observed with mild to severe foliar symptoms of chlorotic streak. No differences were observed in growth, bulb production, flowers, or flowering time between symptomatic and asymptomatic plants, except the symptomatic plants had earlier senescence. Occasionally, the flowers displayed symptoms of chlorosis and white rings in the sepals. Extracts from symptomatic leaves were concentrated by differential centrifugation and analyzed after sucrose gradients. Negative staining of fractions from gradients from symptomatic plants showed the presence of filamentous viral particles 500 by 17 nm. Purified particles contained a single major protein of about 28 kDa as estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDSPAGE) and a single RNA of about 7 kb, which is greater than the 6.2 kb reported (GenBank). These data suggest the presence of a potexvirus in symptomatic plants (1,2). In enzyme-linked immunosorbent assays, symptomatic plants reacted strongly with antiserum specific for Cymbidium mosaic potexvirus (CymMV). This is the first report of CymMV in P. tankervilliae in Costa Rica.es_ES
