Bacillus amyloliquefaciens: Source of barnase and barstar genes for plant biotechnology, enabling male-sterile plant creation. Barnase, a ribonuclease, is toxic to plant cells, inducing male sterility. Barstar inhibits barnase, controlling this effect.
Bacillus subtilis: Primarily recognized for its probiotic properties.
Bartonella henselae: Associated with disease causation.
Barnesiella coli: Predominantly found in the human gastrointestinal tract.
