International Group of Scientists Complete Wild Rice Genome
March 20, 2013 |
Researchers from the Chinese Academy of Sciences, BGI-Shenzen, and University of Arizona have completed the genome sequencing of wild rice Oryza brachyantha. In this collaborative study, researchers generated a high-quality reference genome sequence and found that the compact genome of O. brachyantha was caused by the silencing of LTR (Long terminal Repeats) retrotransposons and massive internal deletions of ancient elements. The team also found that many gene families were expanded in rice.
This new breakthrough provides new insights for better understanding of the functions and evolution of the Oryza genome, the most extended wild relative of O. sativa (rice). O. brachyantha has resistance against many rice pathogens and various stress environments, and proved to have the most compact Oryza.
