University of Queensland researchers have for the first time introduced genetic material into plants via their roots, opening a potential pathway for rapid crop improvement. The research is published in Nature Plants.

Professor Bernard Carroll from UQ’s School of Chemistry and Molecular Biosciences said nanoparticle technology could help fine-tune plant genes to increase crop yield and improve food quality.

“Traditional plant breeding and genetic modification take many generations to produce a new crop variety, which is time-consuming and expensive,” Professor Carroll said.
