The researchers theorize that rice has more genes than humans do because in plants, protein diversity depends on gene duplication. He oversaw the assembly and annotation of the rice genome sequence, and wrote the manuscript that will appear in Science. He is a research scientist at the UW Genome Center, a professor of genome biology at the Chinese center, and a visiting professor at the Chinese Academy of Sciences. Gane Ka-Shu Wong, a Canadian scientist who is another of the four lead authors. But if we pride ourselves on the number of genes in our genome, then we lose to a lowly rice plant,” says Dr. “We all like to believe we as humans are better than anything else, and that we have more of everything. The way you push the field forward is by providing information,” Yu says.Īmong the more surprising lessons: rice has 46,000 to 55,600 genes, while the human genome has only 30,000 to 40,000 genes. “We want to encourage the scientific field to conduct more research on rice. However, the Chinese center is the first to release the full sequence to the public databases. There have been other efforts to sequence rice involving japonica varieties. The researchers say that they have learned quite a lot about rice, but it is still too early to translate their findings into better crops. Rice has the smallest genome among the major cereal crops, and is expected to be a model for other commonly cultivated cereal crops, including corn and wheat, whose genomes are six and 40 times larger than rice. ![]() The sequencing center is also working on the maternal cultivar of LYP9, to better understand why hybrid varieties of rice grow so much more vigorously. It is the paternal cultivar of a super-hybrid rice, LYP9, which has 20 to 30 percent more yield than other rice varieties. indica, that is the most commonly grown in China and many Asian-Pacific areas. The sequence is of the form of rice, Oryza sativa L. There is a reason that researchers began with the variety of rice that they did. Yu says that rice accounts for 40 percent of the grains grown in China. ![]() According to a national survey, cereal grains account for 67 percent of the energy intake in the Chinese diet. Rice is a staple for more than half of the world’s population. ![]() No doubt they will play a very important role in science in the future.” “Their latest achievement, the sequencing of the rice genome, shows that they are still making rapid progress. Merete Fredholm, professor in the Division of Animal Genetics and Breeding of the Royal Veterinary and Agricultural University in Denmark. This demonstrates that they have rapidly gotten up to speed with comparable sequencing laboratories around the world,” says Dr. Their institute joined the Human Genome Project at quite a late stage, but managed to make a substantial contribution. “I am very impressed with the contributions the Chinese genome center has made to large-scale sequencing. He is a research scientist at the UW Genome Center, an associate director of the Chinese center, and a professor with the Chinese Academy of Sciences.Ī collaborator says that the world can expect other significant genomic news from the Chinese center in the future. Jun Yu, an American scientist who is one of the four lead authors on the paper, and the principal investigator for the rice project. There is nothing in the Chinese diet that compares with rice,” says Dr. “If you think about why the Chinese want to sequence rice, it’s the No. Created just a few years ago, the Chinese center is now engaged in the sequencing of two other varieties of rice, as well as the genomes of corn, the pig and the chicken. Among the findings: rice may have more genes than humans. An analysis of the sequence will appear in the April 5 issue of Science, published by the American Association for the Advancement of Science. The Chinese center is making the complete genome sequence of rice available to the public. Gane Ka-Shu Wong, a Canadian – and a major new genome sequencing center in China have sequenced the genetic code for rice, one of the most important food staples in the world.
