TI PLASMID Meaning and
Definition
-
A ti plasmid, also known as a tumor-inducing plasmid, is a type of plasmid found in certain strains of soil bacteria, such as Agrobacterium tumefaciens. This plasmid is commonly associated with causing crown gall disease in plants. Ti plasmids are named after the tumor-inducing ability they possess.
Ti plasmids are circular segments of double-stranded DNA that can replicate independently of the bacterial chromosome. They contain several distinct regions or segments which enable them to transfer specific genes into the host plant's genome.
The key feature that distinguishes a ti plasmid from other plasmids is the presence of the T-DNA (transfer DNA) region. This region is responsible for the transfer and integration of genes from the bacterium into the host plant cell. The T-DNA contains genes that produce plant hormones like auxins and cytokinins, which cause uncontrolled cell growth and result in the formation of galls on the plant.
Furthermore, ti plasmids also possess other regions, such as the vir (virulence) genes, which facilitate their transfer from the bacterium to the plant cell. The vir genes encode proteins involved in the secretion machinery, attachment to the plant cell, and DNA transfer.
Ti plasmids have been extensively studied and utilized in biotechnology as a tool for plant genetic engineering. Scientists have manipulated and modified these plasmids to introduce desired genes into plants, enabling the development of genetically modified organisms (GMOs) with improved traits such as disease resistance, increased yield, or enhanced nutritional content.

Etymology of TI PLASMID
The word "ti plasmid" is an abbreviated form of "tumor-inducing plasmid". This term originated from scientific research conducted in the late 20th century on Agrobacterium tumefaciens, a bacterium known for its ability to cause tumors in plants. The "ti plasmid" refers to the specific plasmid (a small, circular DNA molecule) found in Agrobacterium tumefaciens that is responsible for the tumor-inducing properties. The term was first coined in scientific literature to describe this distinctive plasmid and its role in plant pathology.
