Transgenic Plants

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.

Gene Pollution: Gene pollution, also known as genetic pollution, occurs when genes from a genetically modified organism are transferred to a non-genetically modified organism (especially a related wild species). This transfer often occurs through pollen, as it can travel to nearby related species, causing a change in the genetic structure of that species. It is termed ‘pollution’ because the spread of genes is unregulated, and can cause unexpected effects. Gene Transfer: Gene transfer, while related to the movement of genes, does not specify the negative implications of the escape. It is more of a general term for genetic material transfer, and this might be in a controlled environment. DNA Contamination: DNA contamination refers to the introduction of unwanted DNA into a sample or system which is not necessarily from pollen. This can happen because of laboratory practices, or accidental contamination. Toxicity Transfer: Toxicity transfer refers to the transfer of toxic substances, and this is usually not related to transfer of genetic material.
