Narcissus late season yellows virus and Vallota speciosa virus found infecting domestic and wild populations of Narcissus species in Australia.

摘要

Isolates of Narcissus late season yellows virus (NLSYV) were identified from domestic and wild Narcissus populations at incidences of 66 and 49%, respectively. NLSYV was also detected in one plant of Clivea miniata. Comparisons of nucleotide and amino acid sequences of the coat protein genes of NLSYV isolates showed that they formed three distinct phylogenetic groups, including one not seen before. Vallota speciosa virus was detected in one domestic population of Narcissus sp. where it infected 70% of the plants. This is the first report of these viruses in Australia, and of NLSYV infecting C. miniata.
