  1. Agrobacterium tumefaciens(“AT” for short) By: Jack Foarde & Lauren Netz

  2. What is agrobacterium tumefaciens? • It is the causal agent of many types of tumors in plants. It also causes crown gall disease. • It’s rod-shaped and a Gram negative soil bacterium. • Symptoms are caused by the insertion of a small segment of transfer DNA from a plasmid into the plant cell, which is implanted in a random location in the genome.

  3. What is the role of this organism in making transgenic plants? • Scientists have used the ability of A. tumefaciens to make transgenic plants. • A. tumefaciens can be used and has been used to make GMO plants since the 70s • The AT makes galls in the plant which it then uses as an energy source in the new, modified plant.

  4. Current and potential applications of transgenic plants • The AT can create a new genetic structure in a plant, which scientists have been using for GMOs to use in agriculture and research purposes. • Using AT is a popular way for scientists to manipulate plants because of it’s low amount of genes.
