Graphene, one of carbon nanomaterials, has unique properties such as high electrical conductivity, surface area, and carrier mobility, which is currently regarded as emerging engineering platforms in various fields including agriculture and biological applications. Here, we present graphene oxide (GO) that can provide a positive influence on plant growth. To this end, we approached two methods with indirect and direct stimulation to provide unique structural, mechanical, chemical cues of graphene to plants including Arabidopsis thaliana and watermelon. The GO injected Arabidopsis thaliana showed the enhanced growth such as increased root length, leaf number, leaf area, and flower number. In addition, it was confirmed that the GO injected watermelon showed the enhanced sugar concentration. Our findings suggest that graphene with suitable concentration may provide positive effects on the plant growth as a new tool for rational design of plant growth-assisted agents for future agriculture.
