Gene Shears technology is at the forefront of the fast changing biotechnology industry. The Gene Shears ribozymes breakthrough came from basic research into the molecular structure of a parasite plant virus conducted in Australia by Drs Jim Haseloff and Wayne Gerlach of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) . Although not originally envisaged to lead to such a significant discovery, their work yielded unexpected dividends - the discovery that they could design and create 'hammerhead' ribozymes to target and cut specific Ribonucleic Acid (RNA) molecules.
This discovery means that ribozymes can provide a way to selectively interrupt the operation of, or cut out, genes - hence the name 'Gene Shears'. Gene Shears ribozymes are potentially a very powerful tool that can be directed against genes with harmful or undesirable characteristics.
The Gene Shears technology aims to benefit plant and animal science and the pharmaceutical and food industries.
In agriculture, new technologies associated with Gene Shears aim to secure farmers' incomes, fight plant and animal diseases and benefit the environment. Some examples include:
In human medicine Gene Shears is contributing towards the development of safe and affordable gene therapies for presently incurable diseases. This includes:
