Agrobacterium, a tumor-producing bacterium that infects plants, has been of recent interest because of its possible use as a vector for genetically engineering plants. A. True
B. False

A. True

Explanation:

A tumor producing bacteria named Agrobacterium tumefaciens is very much in use in the field of biotechnology recently. The bacteria consists of a tumor producing gene that is incorporated in the plasmid called as 'Ti plasmid' or the tumor causing plasmid. The gene of the interest is incorporated in the plasmid and the plants is infected by it. In this way the plant receives the gene interest.

This agrobacterium can be used as  a vector in the genetically engineered plants.

Hence the answer is true.

yes, because even though a theory has a  lot of evidence to support it, it is not always true
