Water deficit is currently one of the most significant limiting factors for global agricultural productivity, a factor further exacerbated by global climate change according to a 2019 water report from the Food and Agriculture Organization (FAO) of the United Nations. As a result, researchers worldwide have been working to improve water-use efficiency in crops to better cope with water-scarce conditions. 

It is projected that by the year 2050, the global food supply will need to increase by 50-80% to keep up with the growing population. Researchers all over the world have been working to find ways to sustainably grow food crops to meet this need, and improving photosynthesis in plants holds great possibilities to solving these issues. 

For thousands of years, plants have produced food for humans, but with genetic tweaks, they can also manufacture proteins like Ebola vaccines, antibodies to combat a range of conditions, and now, cellulase that is used in food processing and to break down crop waste to create biofuel.
