19.7 Genetic technology and agriculture
Herbicide resistance
Glyphosate
Inhibits synthesis of certain amino acids
Gene came from
agrobacterium
Cons
Can become agricultural weed if spreads to other fields
Pollen transfers resistance to wild relatives, producing hybrid weeds
Herbicide-resistant weeds evolve over time as same herbicide is used
Insect resistance
Bt toxin
Produced by bacteria
Gene transferred to crop plants to give them insect resistance
Different toxins from different bacteria can be used against different insect species
Cons
Insects evolve resistance
May harm other species
Pollen transfers resistance to wild relatives
GM food
Atlantic salmon given gene for growth hormone from Pacific Chinook salmon, causing it to produce growth hormone throughout the year
Salmon grow all year round and reach full size in 18 months rather than 3 years
