Crops can be made more resistant to insect pests and fungi through the introduction of natural insecticides or fungicides from species with a natural resistance. This reduces the need for chemicals. Plants may also be made more resistant to artificial herbicides which can be sprayed over the entire crop and destroy only the weeds rowing without the resistant gene. Crop's resistance to the cold and drought nay be increased and plants may be able to grow in areas previously unsuitable.
To manipulate genes in plants the specific gene must firstly be detected and then all the cells which have been changed must be preserved and the unchanged cells discarded. The desired gene is given a marker - commonly a tolerance to an antibiotic whi ...
