It did not infect any of 46 other herbaceous genera in families Cucurbitaceae, Fabaceae. Asteraceae, Solanaceae, or Brassicaceae. In gel diffusion tests this virus reacted with antiserum to tobacco streak virus (TSV). Virus in leaves directly from the source shrubs, tested by ELISA, also reacted with TSV antiserum. Examination by electron microscopy revealed isometric particles 27 mm in diameter. The source shrub displayed a general unthrifty condition, chlorosis of leaves on some shoot tips and mild verinal chlorosis. The now 12 foot shrubs were grown from seed imported from China in 1914 (PI 40689). This species is now widely commercially available in the U.S. and grown for its fragrant late winter flowers. Viruses from Lonicera have been reported from Europe, Russia, Japan and Canada. TSV is reported to be seed borne in several other genera. Among other viruses reported from honeysuckle are Lonicera latent carlavirus, tobacco leaf curl germinivirus, alfalfa mosaic virus, tomato bushy stunt virus, a rhabdovirus, and an aphid transmitted virus. |
