Another variety sweet sorghum has a sweet stem and is thus similar to sugar cane. The Food and Agriculture Organization of the United Nations has introduced sweet sorghum in China because of the country's interest in having a biofuel crop and its ability to grow in areas where corn would not. Brazil's extensive biofuel economy is based on sugar cane and is regarded as the most productive biofuel crop in the world. Sweet sorghum rivals sugar cane for this application and sorghum is superior to corn as a biofuel since the entire plant may be used, not just the grain the kernels of corn.
"We now will have a better idea of how many properties of the grasses, such as drought resistance, sugar in the stem, or grain productivity are encrypted in their genes," Messing said. "Knowing this may enable us to laterally move these genes around among these crop species, to customize them based on the needs of geographic location and climate."
