| further characterization of two sequiviruses infecting lettuce and development of specific rt-pcr primers. | lettuce mottle virus (lemov) and dandelion yellow mosaic virus (daymv) infect lettuce in south america and europe, respectively. lemov and daymv possess isometric particles, occur at low concentrations in plants and have narrow host ranges. partial genome sequences of both viruses were obtained using purified viral preparations and universal primers for members of the family sequiviridae. daymv and lemov sequences were analyzed and showed identity with other members of the family. universal prim ... | 2007 | 17238013 |
