INTRODUCTION
Agrobacterium Tumefaciens is an aerobic gram negative bacteria that is commonly known as a causal agent of Crown Gall disease in a wide array of plants. Agrobacterium Tumefaciens uses horizontal gene transfer “which is any process in which an organism transfers genetic material to another cell that is not its offspring.” (Black, Microbiology, pg13) to cause tumors in plants. It causes tumors by transferring a small segment of its DNA and inserting itself in a semi random location in the plants genome.
We investigated the effect Agrobacterium Tumefaciens had on the Kalanchoe plant and how it supported Koch’s Postulates. Koch’s Postulates was designed to determine the causal agents of plant disease and to associate a particular organism with a specific disease. Koch’s Postulates are as follow: (Black, Microbiology, pg13)
1. The specific causative agent must be found in every case of the disease.
2. The disease organism must be isolated in pure......
