Which one of the following bacterium is used for production of transgenic plants
Escherichia coli
Bacillus thuringiensis
Staphylococcus aureus
Agrobacterium tumefaciens
D.
Agrobacterium tumefaciens
Transgenic plants are the plants that have been genetically engineered, a breeding approach that uses recombinant DNA techniques to create plants with new characteritics.
Plant cells do not have endogeneous plasmids. The plasmid vectors used for plant cell transformation are mostly based on Agrobacterium tumefaciens Ti plasmid. These are plant pathogenic Gram ve soil bacteria which cause crown gall disease of dicot plants.
In which stage of its life cycle, the silk moth begins to produce silk fibre?
3rd instar larva
4th instar larva
5th instar larva
Pupa
