Biology - Gene technology

Gene technology

Genetically modified potato plants (left) are able to withstand viral
diseases which can devastate conventional plants (right)

Genetically modified cotton (right) has much higher resistance to insect
attack than conventional cotton (left)

* 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, [1]
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.
