Engineered plants produce sex perfume to trick pests and replace pesticides EarlhamInst
Critically, they've shown how the production of these molecules can be efficiently managed so as not to hamper normal plant growth.
Synthetic biology applies engineering principles to the building blocks of life, DNA. By creating genetic modules with the instructions to build new molecules, Dr. Patron and her group can turn a plant such as tobacco into a factory that only needs sunlight and water. The Group built new sequences of DNA in the lab to mimic the moth genes and introduced a few molecular switches to precisely regulate their expression, which effectively turns the manufacturing process on and off.
"The plants are producing a lot of pheromone but they're not able to grow very large, which essentially reduces the capacity of our production line. Our new research provides a way to regulateIn the lab, the team set about testing and refining the control of genes responsible for producing the mix of specific molecules that mimic the sex pheromones of moth species, including navel orangeworm and cotton bollworm moths.
