Questions and Answers
What defines the T-DNA region of any Ti plasmid?
The presence of the right- and left-border sequences.
What is the function of the 'overdrive' or enhancer sequence in octopine-strain Ti plasmids?
It is required for optimal T-DNA transfer.
How many T-DNA regions do octopine strains have, and what are they called?
Octopine strains have two T-DNA regions, termed ‘TL’ and ‘TR’.
