Research Findings
- The researchers used a whole-genome shotgun sequencing approach to generate 31 Gb of the raw sequence of O. brachyantha using the Illumina GA II platform (Supplementary Table S1). The genome was initially assembled using SOAPdenovo19, and the length of the sequence scaffold was further increased by integrating BAC-end sequences generated by Sanger technology20 (Supplementary Methods). The final assembled sequence was 261 Mb with a scaffold N50 size of 1.6 Mb (Supplementary Table S2). The ordering of the scaffolds along each chromosome was accomplished by integration with the BAC-based physical map20. The scaffolds were eventually merged into 36 large sequence blocks covering 96% of the sequenced genome (Fig. 1). These sequence blocks were anchored onto each chromosome by a cytogenetic approach (Supplementary Fig. S3), resulting in 12 pseudomolecules representing the 12 chromosomes of O. brachyantha.
