A virus identified as AMV on the basis of serology was isolated from a symptomless Jasminum mesnyi introduction. Its experimental host range and physical properties were similar to those reported for AMV. The best of several comparable purification procedures, in terms of virus yield, involved blending tissue in phosphate buffer and chloroform, and concentrating the virus by ultracentrifugation. A rabbit injected with purified virus produced antisera with a titre of 1:1024. C. 60% of the RNA was recovered when extracted using both sodium dodecylsulphate and phenol. Base ratio of the RNA was A=24.9%; C=25.6%; G=21.6% and U=27.9%. [has a huge host range -- http://www.agrobiologicals.com/products/P334.htm]

Anytime you smell the heavy, sweet, nocturnal fragrance of the white, tubular flowers of jasmine (Jasminum, Oleaceae), honeysuckle (Lonicera, Caprifoliaceae), Gardenia (Rubiaceae), Pittosporum (Pittosporaceae), or Stephanotis (Asclepiadceae), excellent candidates for hawkmoth visitation are in the neighborhood. Add to that some of the white-flowered woody Apocynaceae, such as Plumeria, oleander (Nerium oleander), star-jasmine (Trachelospermum jasminoides), or Natal plum (Carissa macrocarpa), and the standard syndrome of floral features begins to take shape. Other sterling, and stunning, examples are such garden herbs as flowering tobacco (Nicotiana sylvestris, Solanaceae) and four o'clocks (Mirabilis jalapa, Nyctaginaceae"
