A new strain of low-methane rice has won Popular Science’s “Best of What’s New” award 2015 for engineering. The new kind of rice, known as SUSIBA2, has been developed by splicing a single gene from barley into rice plants to reduce the amount of methane the rice produces and, ultimately, the amount released into the environment. The single inserted gene does this by altering the transport of carbon within the rice plant. Instead of taking its usual path to the roots, where methane-producing bacteria are found, carbon in SUSIBA2 rice is redirected to the grains and leaves. This has the added benefit of increasing the starch levels and yield of the rice. SUSIBA2 rice has performed well in field trials and will now be assessed for commercial viability.  Continue reading
