Transgenic plants

Definition

Transgenic plants are genetically modified organisms (GMOs) that have genes inserted into their genome from other species, often to introduce desirable traits. They are commonly used in agriculture to enhance resistance to pests, diseases, and environmental conditions.

5 Must Know Facts For Your Next Test

1. Agrobacterium tumefaciens is a common tool used for introducing foreign genes into plant cells.
2. Transgenic plants can be engineered to produce pharmaceuticals, a process known as 'pharming.'
3. One of the first commercially successful transgenic plants was the Flavr Savr tomato, designed for prolonged shelf life.
4. The insertion of foreign genes in transgenic plants is often achieved using plasmid vectors.
5. Concerns around transgenic plants include potential ecological impacts and gene flow to non-target species.
