A mushroom harboring the Gram-positive bacterium C. fischoederii also harbors the Gram-negative bacterium P. frondae. It is known that very rarely, when those two bacteria co-inhabit a mushroom, a change in P. frondae’s genetic makeup can occur, allowing the mushroom to turn into the tasty blue mushroom known as the Wooly Neptune. What are the three distinct mechanisms that can explain how permanent change in the genetic makeup of P. frondae can occur, allowing it to become blue (and tasty)?
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
