Ti plasmids of Agrobacterium. Ti Plasmid. is a large 200 kb plasmid; It has 4 major regions; T-DNA region or transfer DNA region which has genes for auxin, cytokinin and opine; T-DNA region is integrated into the plant genome; A left border and right border repeats; An origin of replication (ori) Virulence region that has genes that mediate T DNA transfer; Opine catabolism region that.
A Ti plasmid mutant was constructed in which all the on-cogenic functions of the T-DNA have been deleted and replaced by pBR322. This Ti plasmid, pGV3850, still mediates efficient transfer and stabilization of its truncated T-DNA into infected plant cells. Moreover, integration and expression of this minimal T-DNA in plant cells does not interfere with normal plant cell differentiation. A DNA.
LAB 12 PLASMID MAPPING STUDENT GUIDE GOAL The objective of this lab is to perform restriction digestion of plasmid DNA and construct a plasmid map using the results. OBJECTIVES After completion, the student should be able to: 1. Perform plasmid DNA mapping. 2. Draw a plasmid map from gel electrophoresis data of the digested recombinant plasmid. 3. Explain each step in construction of a.
Section 7.1 DNA Cloning with Plasmid Vectors. The essence of cell chemistry is to isolate a particular cellular component and then analyze its chemical structure and activity. In the case of DNA, this is feasible for relatively short molecules such as the genomes of small viruses. But genomes of even the simplest cells are much too large to directly analyze in detail at the molecular level.

This review chronicles the development of the plant binary vectors of Ti plasmid in Agrobacterium tumefaciens during the last 30 years. A binary vector strategy was designed in 1983 to separate the T-DNA region in a small plasmid from the virulence genes in avirulent T-DNA-less Ti plasmid. The small plant vectors with the T-DNA region have been simply now called binary Ti vectors.
