Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Bacillus amyloliquefaciens: This bacterium is the natural source of the barnase and barstar genes which are used in plant biotechnology to create male-sterile plants. The barnase gene encodes for a ribonuclease enzyme that is toxic to plant cells, causing male sterility. The barstar gene produces a protein that inhibits the barnase enzyme, thus preventing its harmful effects and allowing for the controlled induction of male sterility.
Bacillus subtilis: Though it is a bacteria, it is mainly known for its probiotic nature.
Bartonella henselae: This bacterium is more related to causing diseases.
Barnesiella coli: This bacterium is mainly found in the human gut.
