Description
Climate change has the potential to reduce the amount of land that is suitable for crop growth. Such changes may cause food shortages, which would most likely disproportionately affect the poorest regions of the world. While GMO crops showed potential to increase crop yield and agricultural efficiency, significant public pushback has led to a search for alternative methods to generate similar results. Compounds produced by bacteria, such as 2,3-butanediol, offer a potential way to change the phenotypes of plants without the deliberate genomic changes involved in the development of GMOs which are often the subject of great controversy. These compounds influence how plants grow and function. Through precise application, the compounds could be used to improve crop yield and stress tolerance. While these effects are not completely understood, they may be due to changes in transcription and translation of certain proteins, the microbiome surrounding the plants and its interactions with the compounds, or other unknown factors. The compound 2,3-butanediol appears to increase biomass, lead to larger root systems and more root hairs, and increase germination rates in a variety of plants. All these traits are favorable for producing higher yields and enduring stress conditions. The phenotypes induced by this compound are similar to plants engineered to over express a type I proton pyrophosphatase. Plants treated with 2,3-butanediol offer a potential option to achieve the benefits of GMO crops without the attached social stigma.
