Biology - Gene technology

Gene technology

The CSIRO web page at http://genetech.csiro.au/research/index.htm
provides up-to-date information about gene technology

There are many examples of applied genetic research and accomplishments
throughout the world (for example, in Australia). These include:

* - vector [1] nasal sprays to help treat CF sufferers

* against a number of diseases of humans and other animals

* Potato plants have had genes inserted to make them the causing leaf
roll

* has been made by genetically manipulated bacteria

* Some tomatoes have had a 'non-squashy gene' inserted so tomatoes as
they ripen

* The cotton budworm has devastated cotton plants in some areas; cotton
plants have been made by inserting a gene for the production of an
insecticide. This has reduced the use of expensive chemical pesticides and
the likelihood of insects becoming resistant to the pesticides

* A sunflower gene has been inserted in sub-clover plants to make them
produce a for livestock

* Viruses are being developed to carry introduced genes for producing to
target insect larvae

* Carnations can be made to last longer by inserting a gene ethylene
causes petals to curl up and die after about eight days

* Sheep can be made to by inserting extra 'wool' genes

* Researchers have taken the gene coding for a plant enzyme, [2]
chitinase, and modified it so it will

* Vaccines are being developed for which are and buffalo flies; cattle
'fever' costs the industry over $150 million dollars a year

* Researchers have produced a live genetically engineered virus which
perhaps other feral animals such as foxes and rabbits could be controlled
in this way.
