parthenium tomentosum/ニコチン

Tobacco streak virus incidence in the cotton field, cv CO14 at Department of Cotton, Tamil Nadu Agricultural University (TNAU), Coimbatore, India was nearly 36.50%. Cotton plants infected with TSV exhibits different types of symptoms, including necrotic spots, lesions, mosaic, purplish necrotic

Tobacco streak virus (TSV) was found to commonly occur in Parthenium hysterophorus, as symptomless infections, in central Queensland, Australia across a large area infested with this weed. Several isolates of TSV collected across the geographic range of P. hysterophorus were found to share identical

This is the first report of the genetic diversity within ilarvirus subgroup 1 from eastern Australia. It supports the separation of tobacco streak virus (TSV) strains from parthenium (Parthenium hysterophorus) and crownbeard (Verbescina encelioides) based on serology and host specificity. It has
