anemone altaica/nicotine

A previous report (1) drew attention to the occurrence in the U.S. of tobacco rattle tobravirus (TRV) in several perennial ornamentals that move freely in international trade. Here we report the occurrence of TRV in an additional host plant of this type. The virus was identified in anemone (Anemone

Unequivocal evidence of the viral nature of virus-like particles observed at the specific site of retention of tobacco rattle virus (TRV) in Paratrichodorus and Trichodorus nematodes has not previously been available. A new staining technique using safranin-O, which does not affect viral

Ranunculus white mottle virus (RWMV) (1), genus Ophiovirus, has been reported in crops of several cultivars of commercial ranunculus (Ranunculus asiaticus hybrids) during the 1990s in Liguria in Northwest Italy. Symptoms associated with RWMV in ranunculus are not clear-cut owing to the presence of

In the spring of 2008, more than a dozen, aphid-infested, anemone plants (Anemone sp.) grown at the campus of the University of Arkansas in Fayetteville showed stunting and mosaic, whereas only two were asymptomatic. Leaf homogenates from four symptomatic plants were inoculated onto Nicotiana

Feeding by P. anemones, an efficient vector of tobacco rattle virus (TRV), was investigated by video-enhanced interference light microscopy. Four stages were observed after transfer of individual nematodes, extracted from soil, to Nicotiana tabacum seedling roots in agar: i) acclimatisation; ii)
