Biotechnology improves crops by tailoring their properties or transferring properties from one organism to another. Both these processes involve working with the organisms’ genes (that determine genetic characteristics), made possible by advances in genetic engineering.
Genetic engineering has already benefited the textile industry and promises much more. For example, cotton, which is the leading fiber used by the textile industry, is vulnerable to attacks by many insects. Cotton also has poor tolerance against herbicides used to kill weeds in irrigated cotton fields. By working with the genes of the crop, scientists are hoping to develop insect and herbicide resistant varieties of cotton.
Another objective is to develop cotton varieties that will be naturally colored, say blue or vivid red, so that bleaching and dyeing of textiles can be eliminated. Research is also going on to provide other desirable properties at a genetic level.
In Australia, sheep is being “engineered” to secrete an insect repellant from its hair follicles to resist attacks from blowfly, and also stop hair growth so that wool can be “pulled off” instead of being sheared. Shearing wool from sheep is a cumbersome and time-consuming process.
Biotechnology is helping not only such genetic engineering results but is also helping in disease diagnostics and new forms of therapy, for example.
