Loren Rieseberg, a University of British Columbia collaborator, will compare their genetic profiles to those of American
wild sunflowers. This could reveal whether the Australian sunflowers have undergone significant genetic changes since arriving in the Land Down Under more than 100 years ago from America.
Snow and her colleagues are continuing their research and trying to understand if
wild sunflowers with beneficial transgenes could become troublesome weeds.
The Nevada desert is not at all like that - it's alive with colour, mile upon mile of
wild sunflowers grow along the roadside and yucca, aloe vera and Joshua trees grow in the sandy soil above acres of bright yellow flowers that give the whole landscape a golden glow.
SUNFLOWER CHLOROTIC MOTTLE VIRUS (SuCMoV), a member of the Potyvirus genus within the Potyviridac family (Dujovny et al., 1998, 2000), is one of the most widely distributed potyviruses on cultivated and
wild sunflowers in Argentina (Lenardon et al., 2001).
* Ohio State University, Columbus, Ohio -- $230,000 to study transgenic insect resistance effects on
wild sunflowers.
When researchers crossed these souped-up plants with
wild sunflowers, the Bt gene passed to some of the offspring, report Allison Snow of Ohio State University in Columbus and her colleagues.
These plants include melons, cucumbers, carrots, chicory,
wild sunflowers, herbaceous ornamentals, and shrubs, as well as species of Brassica and Cuphea.
Genes for resistance to the new race have been identified in cultivated and
wild sunflowers and seem to confer resistance to earlier races (A through E), as has been the historical pattern (Vranceanu et al., 1980, 1986; Melero-Vara et al., 1989; Dominguez, 1996a; Ruso et al., 1996; Gagne et al., 1998; Sukno et al., 1998, 1999; Fernandez-Martinez et al., 2000).
