| a new potyvirus from butterfly flower (iris japonica thunb.) in zhejiang, china. | a filamentous virus isolated from iris japonica with mosaic symptoms was pathogenic to i. japonica and i. bulleyana but not to 12 virus indicator species. sequencing of the 3'-terminus of the genome showed that it was a potyvirus, most closely related to sunflower mosaic virus (63.2% identical), and phylogenetic analysis also showed a more distant grouping with tobacco etch and colombian datura viruses. the virus was detected by rt-pcr in symptomatic i. japonica plants from several regions of ch ... | 2008 | 18183351 |
| host range and characterization of sunflower mosaic virus. | abstract sunflower mosaic is caused by a putative member of the family potyviridae. sunflower mosaic virus (sumv) was characterized in terms of host range, physical and biological characteristics, and partial nucleotide and amino acid sequence. cells infected with sumv had cytoplasmic inclusion bodies typical of potyviruses. of 74 genera tested, only species in helianthus, sanvitalia, and zinnia, all asteraceae, were systemic hosts. commercial sunflower hybrids from the united states, europe, an ... | 2002 | 18943264 |
