Now, a large dataset on genetic functions in rice
Washington, March 14 (ANI): Biologists at the University of Delaware have developed a large gene dataset for rice plant, which may lead to a better understanding of how genes work in the grains that are used as food by a large part of the world's population. Blake Meyers, a plant biologist at the University of Delaware, and colleagues used gene sequencing technologies and high-powered computer-based approaches to examine both normal gene expression (mRNA) as well as small ribonucleic acids (RNA) in rice. The analysis of rice was based on gene sequences representing nearly 47 million mRNA molecules and three million small RNAs, a larger dataset than has been reported for any other plant species. Meyers says that since small RNAs are very small as compared to mRNAs, they went unnoticed for many years, or were considered biologically unimportant. He further said that small RNAs play an important role in gene regulation, and that deficiencies in their production could have a profound effect on development. "Small RNAs also have been associated with other important biological processes, such as responses to stress," he said. "Many of small RNAs in rice have related sequences in the many important cereal crop plants, including maize and wheat," he added. Machi Dilworth, Director of the National Science Foundation (NSF)'s Division of Biological Infrastructure, said that research on small RNAs was a leading edge in plant biotechnology. "This work will contribute to an understanding of the role of small RNAs in gene expression not only in rice, but in all plants," he said. The researchers reported their results in the on-line issue of the journal Nature Biotechnology. (ANI)
