The first crop plant genetically engineered to release an insect pheromone for defence
Insect pheromones offer potential for managing pests of crop plants. Volatility and instability are problems for deployment in agriculture but could be solved by expressing genes for the biosynthesis of pheromones in the crop plants. This has now been achieved by genetically engineering a hexaploid variety of wheat to release (E)-β-farnesene (Eβf), the alarm pheromone for many pest aphids, usin...
متن کاملGenetically Engineered, Embryo-specific Lethality for Insect Pest Management
Many insects compete with us humans for agricultural resources, feed on us, or act as disease vectors. Current control efforts rely mostly on the use of insecticides. The use of chemicals to either repel or kill insect pests is the oldest and most commonly used method of pest control. However, with the massive use of insecticides four major problems have arisen. First, many pests have developed...
متن کاملThe Multiple Strategies of an Insect Herbivore to Overcome Plant Cyanogenic Glucoside Defence
Cyanogenic glucosides (CNglcs) are widespread plant defence compounds that release toxic hydrogen cyanide by plant β-glucosidase activity after tissue damage. Specialised insect herbivores have evolved counter strategies and some sequester CNglcs, but the underlying mechanisms to keep CNglcs intact during feeding and digestion are unknown. We show that CNglc-sequestering Zygaena filipendulae la...
متن کاملGenetically engineered rice resistant to rice stripe virus, an insect-transmitted virus.
The coat protein (CP) gene of rice stripe virus was introduced into two japonica varieties of rice by electroporation of protoplasts. The resultant transgenic plants expressed the CP at high levels (up to 0.5% of total soluble protein) and exhibited a significant level of resistance to virus infection. Plants derived from selfed progeny of the primary transformants also expressed the CP and sho...
متن کاملPSEUDOMONAS FLUORESCENs GENETICALLY ENGINEERED TO PRODUCE AN INSECT TOXIN: A CULM:lNATION OF FIVE
The bacterium Bacillus thuringiensis has been used as a microbial insecticide for half a century. However, limitations on its use against a pest such as Eldana saccharina Walker are that: a) B. thuringiensis is a soil-inhabiting organism and is therefore not persistent on plants, and b) the proteinaceous insecticide is degraded by sunlight when the bacterial cells lyse at the end of their life ...
