Question

Explain ti-plasmid mediated gene transfer with illustrations.

Answer 1

ti plasmid mediated gene
Transfer DNA - Wikipedia The transfer DNA (abbreviated T-DNA) is the transferred DNA of the tumor-inducing (Ti) plasmid of some species of bacteria such as Agrobacterium tumefaciens and [[Agrobacterium rhizogenes](actually an Ri plasmid)]. The T-DNA is transferred from bacterium into the host plant's nuclear DNA genome.

Answer 2

Answer:

“Activated” Agrobacterium transfers a particular gene segment called transfer DNA (T-DNA) from the Ti plasmid. After T-DNA is stably integrated into the chromosomal DNA in the nucleus of the host plant, genes for opine synthesis and tumor-inducing factors on the T-DNA are transcribed in the infected cells.
