Rice, the most widely consumed food crop in the world, takes a beating in hot weather. To combat the high temperatures, a global group of scientists, led by a University of Florida researcher, has found the genetic basis to breed a more heat-tolerant rice cultivar.<\/p>\n

\u201cThe productivity of rice, one of the three major cereal grains feeding the world, is often affected by temperature extremes, especially higher-than-optimal temperatures,\u201d said Bala Rathinasabapathi, a professor of horticultural sciences at the UF Institute of Food and Agricultural Sciences.<\/p>\n

\nTemperatures above 32 degrees Celsius, or just under 90 degrees Fahrenheit, can damage rice, according to multiple studies performed in rice-growing regions of the world.<\/p>\n

Nearly 90 percent of the world\u2019s rice is produced and consumed in Asia, according to the Food and Agriculture Organization of the United Nations. In the U.S., rice grows mainly in Arkansas, California, Louisiana, Missouri and Texas. Some rice also grows in Florida.<\/p>\n

Rathinasabapathi led a recent study in which researchers discovered DNA markers associated with heat tolerance that may lead to a more heat-tolerant rice variety. He explained the use of DNA markers like this: Just as police can identify people by their fingerprints, scientists identify genes they\u2019re interested in by DNA variations that are closely associated with the genes.<\/p>\n

Scientists usually find DNA markers very close to the genes of interest. They call these \u201ccandidate genes,\u201d Rathinasabapathi said. Thus, plant breeders can select plants containing the desired combination of DNA markers to efficiently identify plants with desirable genes and characteristics controlled by those genes.<\/p>\n

That\u2019s the process scientists used in the new study. They studied a population of rice plants derived by crossing a variety from India called \u2018Nagina 22\u2019 with another line called \u2018IR64,\u2019 a variety developed by the Philippines-based International Rice Research Institute, using conventional breeding methods.<\/p>\n

\u2018Nagina 22\u2019 grows better and thus produces more rice than other varieties, even under extreme heat, Rathinasabapathi said. But the quality of the rice is not as high as some varieties, including \u2018IR64,\u2019 he said.<\/p>\n

A future research goal would be to use the DNA markers generated in this study to select for \u2018Nagina 22\u2019 candidate genes for heat tolerance, combined with other traits from \u2018IR64\u2019 into one variety, he said.<\/p>\n

Newton Kilasi, a former UF\/IFAS doctoral student, Eduardo Vallejos, a UF\/IFAS associate professor and Jugpreet Singh, a former UF\/IFAS post-doctoral researcher \u2013 all in horticultural sciences \u2014 were among the scientists who helped Rathinasabapathi with the new study. The research is published in the journal Frontiers in Plant Science.<\/p>\n
