Agrobacterium tumefaciens is a pathogen of several dicot plants. It delivers a piece of DNA known as ‘T-DNA’ in the Ti plasmid which transforms normal plant cells into tumour cells to produce chemicals against pathogens.
The restriction enzyme Eco RI, is isolated from Escherichia coli RY13.
The first restriction enzymes Hind II was isolated from bacterium Haemophilus influenzae. The restriction enzyme Bam HI is isolated from Bacillus amyloli.
