Which one of the following is commonly used in transfer of foreign DNA into crop plants ?
Which one of the following is commonly used in transfer of foreign DNA into crop plants ?
Penicillium expansum
Trichoderma harzianum
Meloidogyne incognita
Agrobacterium tumefaciens
Solution
Agrobacterium tumefaciens is a soil bacterium that is widely used in genetic engineering for transferring foreign DNA into plant cells. It naturally causes crown gall disease in plants by transferring a part of its DNA (T-DNA) into the plant genome. This ability has been harnessed for the introduction of foreign genes into plant genomes in a controlled manner, making it one of the most common tools for plant genetic transformation.
