The Ti plasmid is derived from Agrobacterium tumefaciens, which is a plant pathogen. This plasmid is commonly used as a vector to transfer foreign genes into plant cells in genetic engineering applications.
transfer of gene with the help of Ti plasmid present in Agrobacterium which has T-dna region by which gene van transfer.
The Ti plasmid is naturally found in the bacterium Agrobacterium tumefaciens. This bacterium is known for its ability to transfer genetic material into plant cells, causing the formation of galls or tumors.
Ti plasmid functions to induce turmor or a desease known as "crown gall" to the most dicot (rarely monocot) plants. Transfer DNA or T-DNA will be released during the infection process into the plant cell and integrate with the DNA host. Hence, the plant host is already infected. That's the important function of the Ti plasmid, if there are no such plasmid exist, then the agrobacterium lost its pathogenic function.
Using agrobacterium is the most common way of genetically modifying plants. Inside the bacterium there is a circular piece of DNA called a plasmid, which also has a chromosome. This TI plasmid is tumor inducing but it transfers the plasmid DNA by infecting the plants DNA (it cuts the chromosome of the plant and inserts the plasmid). The bacterium live inside the tumor of the plant. Scientists tooks the T dna, removed the tumor causing genes, and left the DNA splicing genes. They then use the bacterium to transfer the DNA they want.

A plasmid containing a gene for human growth hormone can be used in genetic engineering to produce recombinant human growth hormone. This plasmid can be introduced into host cells, such as bacteria, for the production of the hormone on a large scale.

The Ti plasmid was discovered by Mary-Dell Chilton in the 1970s while she was studying Agrobacterium tumefaciens, a bacterium that causes plant tumors. This discovery led to the development of techniques for genetic engineering in plants.
The Ti plasmid is a circular DNA molecule found in Agrobacterium species. It serves as a vector for transferring genes into plant cells, leading to the formation of crown gall tumors. The transferred genes help the bacterium infect and genetically modify the plant cells to its advantage.
A plasmid is like a bonus toolbox that some bacteria carry with extra tools to help them survive. Just as a toolbox contains additional resources beyond the basic necessities, a plasmid provides extra genetic material to confer specific advantages to bacteria, such as antibiotic resistance or the ability to break down certain compounds.
Recombinant Ti plasmids are used in genetic engineering to introduce foreign DNA into plant cells. This is done by Agrobacterium-mediated transformation, where the Ti plasmid delivers the desired DNA into the plant genome, allowing for the expression of novel traits or genes in the plant.
