Potato latent virus: a proposed new species in the genus Carlavirus
Plant Pathology 51 (4), 495-505
Abstract: A previously undescribed carlavirus, potato latent virus (PotLV), was found infecting the potato cultivar Red La Soda imported from the USA. The particles were filamentous and slightly curved, with modal lengths of 530 and 670 nm. The 11 kDa protein encoded downstream from the coat protein contained a 'zinc-finger' motif characteristic of carlaviruses, and RT-PCR using a carlavirus-specific primer gave a PCR product of 857 bp. Antibodies produced to PotLV did not detect other carlaviruses when used in ELISA and the coat-protein nucleic acid sequence of PotLV showed < 67% similarity with the other carlaviruses tested. The closest similarity was with the Andean strain of potato virus S. Unusually for a carlavirus, PotLV systemically infected Nicotiana bigelovii, N. glutinosa, N. rustica, N. tabacum and Physalis floridana.
