Using reverse genetics, people can figure out the function of specific sequences and areas of the genome. "Application of Reverse Genetics in Functional Genomics of Potyvirus." However, influenza viruses undergo continual antigenic variation, which requires either the annual reformulation of seasonal influenza vaccines or the rapid generation of vaccines against potential pandemic virus strains. NIH Chang GH, Luo BJ, Lu P, Lin L, Wu XY, Li J, Hu Y, Zhu QY. Reverse genetic technology provides an opportunity of developing potyviruses into vectors for improving agronomic traits in plants, as a reporter system for tracking virus infection in hosts or a production system for target proteins.

In vitro and in vivo expression of foreign genes by transmissible gastroenteritis coronavirus-derived minigenomes. Influenza virus infections represent a serious public health and economic problem, which are most effectively prevented through vaccination. Nature is the true master of manipulating genes, and scientists are just trying to keep up with what Mother Nature has intended. Viruses are indeed responding to our medicines, but unfortunately, they are just staying one step ahead of us and we need to keep fighting to survive for our own sake. 1992;66:1129–1138. 2011 Feb;26(1):19-29. doi: 10.1007/s12250-011-3145-x.

Despite the ongoing efforts, in the majority of patients the cause of the disease remains elusive, a phenomenon often referred to as “missing heritability”. Reverse genetics is an approach to genetics research which takes an unknown genetic sequence and attempts to figure out the phenotype with which it is associated. Swietlik, E.M.; Prapa, M.; Martin, J.M. Evol. those of the individual authors and contributors and not of the publisher and the editor(s). This is in contrast with classical genetics, in which researchers take a known phenotype, such as stripes on a cat, and try to determine which gene or genes cause the phenotype to appear.

The segmented nature of influenza virus allows for the reassortment between two or more viruses within a co-infected cell, and this characteristic has also been harnessed in the laboratory to generate reassortant viruses for their use as either inactivated or live-attenuated influenza vaccines. Researchers can introduce mutations, deletions, additions, or other changes to the sequence which should change the way in which it expresses. Palese P.S., Shaw M.L.

Kannan M, Zainal Z, Ismail I, Baharum SN, Bunawan H. Application of Reverse Genetics in Functional Genomics of Potyvirus. In this review, we will summarize the current knowledge of state-of-the-art, plasmid-based, influenza reverse genetics approaches and their implementation to provide rapid, convenient, safe and more effective influenza inactivated or live-attenuated vaccines. While I know some of this has to do with our obsession with "cleanliness" I think that a few of the mutated strains are probably our own doing.
