Using computational programs developed at the Beijing Genomics Institute, Jun Yu led a team that improved the genome assemblies of both indica and japonica rice cultivars and compared the genomes to understand its evolutionary history.
Duplicated segments account for 65.7% of the genome. That was more than expected, says Pat Heslop-Harrison at the University of Leicester: "We thought the duplication of genes as well as repeats could not be easily coped with and would lead to genomic imbalances."
Yu's team is now using microarrays to look at hybrid rice strains and compare them to parental cultivars. A better understanding of hybrid rice is important, according to Yu,...
