Queensland University of Technology:
Taking genetic modification to a new level
The research will focus on cisgenics and RNAi technologies leading to the development of marker-free genetic transformations systems in vegetatively propagated crops, which essentially means modifying the plant using genes from its own species. This method differs from traditional genetic modification which involves adding outside genetic material - often derived from bacteria - as markers into the plant DNA.
Initially, the target crops will be bananas and potatoes as they are among the top 10 crops in the world; however the platform technologies will have potential to be shared in other crops across the horticulture industry.
The researchers are quietly confident that the method will help shift negative public perceptions of genetically modified foods due to the fact that no outside genetic material is being introduced into the plant using the methods proposed.
Research will also be conducted into discovering techniques to provide stability of introduced genes across generations. This will ensure that the genetic improvements made to the original variety are carried on to the next generation.
"This has previously been a challenge due to what's known as 'gene silencing' which is where other genes in the original DNA prevent the new and desired trait from being expressed in later generations," Professor Dale explained.
Alok Kumar, Breeding and Biotechnology Portfolio Manager at HAL added, “This project aims to build capacity for the horticulture industry to be ready for future challenges. The outcomes of this project can only be realised in a long term, up to 2025, as a number of complex issues are targeted. However the potential to shift the industry as we know it makes it a truly transformational project.”
