| Popis: | S ince 1975 the luteoviruses have been recognized as a plant virus group by the International Committee on Taxonomy of Viruses (58). At that time only three viruses were listed unequivocally as members of the group and 13 others as possible members. The list of definite members increased until 1982 when there were 15. S ubsequently, several have been identified as synonyms and the number of members has been reduced to 12 (41) and will probably decrease further. This change in the status of members of the luteovirus group reflects the state of luteovirus taxonomy and results from the naming of many luteoviruses on the basis of host range. As more antisera, cDNA probes, and genomic sequences become available, the relationships of these viruses are being reevaluated on the basis of multiple traits that include host range, serology, nucleic acid homologies, and vector relationships (8, 10,40,65). The name of the group is derived from Latin "luteus," which means yellow, since all original members of the group caused yellowing symptoms in their hosts. Luteoviruses generally are phloem-limited in their hosts, are not trans mitted mechanically, and are transmitted in persistent manner by their aphid vectors (15). Luteoviruses do not appear to replicate in their aphid vectors (16). Most luteoviruses have a limited host range (e.g. potato leafroll virus |
