Millions of people in Asia are dependent on rice as a food source. Believed to have been domesticated as early as 6000 BCE, rice is an important source of calories globally. In a new study, researchers compared domesticated rice to its wild counterparts to understand the differences in their photosynthetic capabilities. The results can help improve future rice productivity.
On October 29th, the Realizing Increased Photosynthetic Efficiency (RIPE) project will be featured on an episode of Follow the Food on BBC World News. Hosted by world-renowned ethnobotanist James Wong, the multimedia series focuses on the biggest pressures on the world food system including RIPE’s central mission of how to feed the growing population, and climate change, which is the focus of the current season.
Bioenergy from crops is a sustainable alternative to fossil fuels. New crops such as energycane can produce several times more fuel per acre than soybeans. Yet, challenges remain in processing the crops to extract fuel efficiently.
Four new studies from the University of Illinois explore chemical-free pretreatment methods, development of high-throughput phenotyping methods, and commercial-scale techno-economic feasibility of producing fuel from energycane in various scenarios.
Scientists have proposed a range of technological options for sustainable, productive and resilient agriculture, providing multiple ways to remove CO2 from the atmosphere and helping to directly mitigate climate change.
In a freshman biology class, a simple demonstration comprises a candle and a plant in an enclosed space. Through the process of photosynthesis, carbon dioxide emitted by the candle is converted into oxygen by the plant, allowing the candle to last longer. For 18-year-old Bailey Goldstein, this experiment sparked his interest in photosynthesis.
The flag leaf is the last to emerge, indicating the transition from crop growth to grain production. Photosynthesis in this leaf provides the majority of the carbohydrates needed for grain filling--so it is the most important leaf for yield potential. A team from the University of Illinois and the International Rice Research Institute (IRRI) found that some flag leaves of different varieties of rice transform light and carbon dioxide into carbohydrates better than others. This finding could potentially open new opportunities for breeding higher yielding rice varieties.
Five years ago, the United Nations committed to achieving the Sustainable Development Goal of Zero Hunger by 2030. Since then, however, world hunger has continued to rise. Nearly 9 percent of our global population is now undernourished, according to a 2020 report from the FAO, and climate variability is a leading factor driving us off course.
