A current perspective on insect gene transformation.
The genetic transformation of non-drosophilid insects is now possible with several systems, with germ-line transformation reported in published and unpublished accounts for about 12 species using four different transposon vectors. For some of these species, transformation can now be considered routine. Other vector systems include viruses and bacterial symbionts that have demonstrated utility i...
متن کاملGENETIC ENGINEERING OF INSECT TOLERANCE IN VAUruT: IMPROVED TRANSFORMATION EFFICIENCY
The genes encoding the insecticidal crystal proteins (ICPs) of BacIllus thuringiensis are good candidates for protecting walnut plants against insect pests. Ve have estimated the dose response of three important walnut pests (codling moth, navel orangeworm and Indianmeal moth) with two highly purified insecticidal proteins of Bacillus thurJ.nglensis and show that these three insects are highly ...
متن کاملFirst Steps towards Underdominant Genetic Transformation of Insect Populations
The idea of introducing genetic modifications into wild populations of insects to stop them from spreading diseases is more than 40 years old. Synthetic disease refractory genes have been successfully generated for mosquito vectors of dengue fever and human malaria. Equally important is the development of population transformation systems to drive and maintain disease refractory genes at high f...
متن کاملtransformation of insect and herbicide resistance genes in cotton (gossypium hirsutum l.)
manipulation of different genes in crop plants to get desirable characters has become an important tool of plant biotechnology. in the current study, cotton variety mnh-786 was modified for its characteristics to show resistance against lepidopteran insects and herbicide by transformation of cry1ac+cry2a and gtgene cloned in a different cassette under 35s promoter. mature embryos of cotton mnh-...
متن کاملDevelopment of Marker-Free Insect-Resistant Indica Rice by Agrobacterium tumefaciens-Mediated Co-transformation
Agrobacterium-mediated co-transformation is an efficient strategy to generate marker-free transgenic plants. In this study, the vectors pMF-2A∗ containing a synthetic cry2A∗ gene driven by maize ubiquitin promoter and pCAMBIA1301 harboring hygromycin phosphotransferase gene (hpt) were introduced into Minghui86 (Oryza sativa L. ssp. indica), an elite indica restorer line. Two independent transfo...
