Answer:
<em>Agrobacterium</em> <em>tumefaciens</em> is a gram negative bacteria that is responsible for tumor formation in the different parts of plant body.
Explanation:
It causes crown-gall disease in plant body by transferring it's DNA into the plant body which include Ti plasmid.
There are 3 types of bacteria that form tumor in different plant ares.
<em>Agrobacterium rhizogenes</em>,<em> Agrobacterium tumefaciens</em> strains contain either Ti or Ri plasmid but <em>Agrobacterium vitis</em> contain only Ti plasmid which are virulent.
The transfer of T-DNA takes place into the body of host cells and then the DNA is expressed into the body of the host and thus forming gall or tumor.
