In a groundbreaking development, researchers at the University of Queensland have introduced a revolutionary approach to improve crop efficiency by delivering genetic material into plants via their roots. This innovative research, featured in the prestigious journal Nature Plants, could significantly impact agriculture and food production by facilitating quick genetic modifications.
The core of this advancement is the employment of nanoparticles, which are specially crafted to penetrate the rigid cell walls of plants—known for being more challenging to breach than those of animals or humans. These nanoparticles are coated with specific proteins to facilitate their entry and efficiently transport synthetic messenger RNA (mRNA) into the plant cells. mRNA is crucial in regulating biological functions and improving plant attributes.
Professor Bernard Carroll, who spearheads this project at UQ’s School of Chemistry and Molecular Biosciences, emphasizes the potential this technology holds in enhancing crop yields and quality. Traditional genetic modification and breeding are often time-consuming and resource-intensive, but the nanoparticle method offers a streamlined alternative. By traveling with water absorbed by the roots, the nanoparticles distribute the genetic material throughout the plant swiftly.
In the study, the team successfully introduced mRNA encoding a fluorescent protein into multiple plant species, including Arabidopsis, achieving visible results that confirmed the viability of their method. The mRNA is expressed transiently before degrading, mirroring the working mechanism of mRNA vaccines and ensuring the plant modifications are temporary and controlled.
UniQuest, UQ’s commercialization arm, has already patented the nanoparticle delivery technology and is seeking partners to further develop and enhance this process. The collaboration involves eminent scientists like Professor Gordon Xu and Dr. Jiaxi Yong, highlighting the strong cooperative effort driving this innovative research.
