New resistance mechanism in Helicoverpa armigera threatens transgenic crops expressing Bacillus thuringiensis Cry1Ac toxin.
In Australia, the cotton bollworm, Helicoverpa armigera, has a long history of resistance to conventional insecticides. Transgenic cotton (expressing the Bacillus thuringiensis toxin Cry1Ac) has been grown for H. armigera control since 1996. It is demonstrated here that a population of Australian H. armigera has developed resistance to Cry1Ac toxin (275-fold). Some 70% of resistant H. armigera ...
متن کاملEngineered gray mold resistance, antioxidant capacity, and pigmentation in betalain-producing crops and ornamentals.
Betalains are tyrosine-derived red-violet and yellow plant pigments known for their antioxidant activity, health-promoting properties, and wide use as food colorants and dietary supplements. By coexpressing three genes of the recently elucidated betalain biosynthetic pathway, we demonstrate the heterologous production of these pigments in a variety of plants, including three major food crops: t...

15 صفحه اولA new Phytoreovirus infecting the glassy-winged sharpshooter (Homalodisca vitripennis).
A new virus species of the genus Phytoreovirus was isolated from glassy-winged sharpshooter (GWSS), Homalodisca vitripennis Germar (Hemiptera: Cicadellidae), in California and designated here as Homalodisca vitripennis reovirus (HoVRV). Extraction of nucleic acid from GWSS adults collected from three Californian populations revealed an array of double-stranded (ds) RNA species that was soluble ...
متن کاملOrnamentals Northwest Archives
Many cultivars of ornamental conifers are difficult to propagate. Cuttings may root poorly and graft success may be highly variable even in the hands of skilled, experienced propagators. Because of these problems, we conducted a detailed study of the physiology of graft formation in Picea pungens 'Hoopsi' scions grafted on Picea abies rootstocks with the purpose of identifying factors limiting ...
