What is transgenic plant ? Give two examples.
Answers
Explanation:
Examples of transgenic plants: (i) Bt cotton (ii) Flavr savr tomato and (iii) Golden rice. (i) Bt Cotton : Bt cotton is a transgenic plant. Bt toxin gene has been cloned and introduced in many plants to provide resistance to insects without the need of insecticides.
What is transgetic plant ?
Ans.Genetically modified plant
Genetically modified plant
Genetically modified plant What is transgenic
Genetically modified plant What is transgenic Genetically modified plants have been engineered for scientific research, to create new colours in plants, deliver vaccines, and to create enhanced crops. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors.
Answer:
(1) The genetically engineered crop plants carrying desirable traits are called transgenic plants. <br> (2) Transgenic plants are disease resistant, insect resistant and herbicide resistant. <br> (3 ) Plants with greater photosynthetic activity, nitrogen fixing ability, improved storage proteins and higher vitamin contents are transgenic plants. <br> (4) Examples of transgenic plants: (i) Bt cotton (ii) Flavr savr tomato and (iii) Golden rice. <br> (i) Bt Cotton : Bt cotton is a transgenic plant. Bt toxin gene has been cloned and introduced in many plants to provide resistance to insects without the need of insecticides. <br> (ii) Flavr savr tomato : It is developed by introducing an additional copy of polygalactouronase. This type of tomato has a longer shelf life. <br> (iii) Golden rice : It is a genetically engineered rice with higher beta carotene (provitamin A) content.
