A List of all Supplementary files 16 files with a total size: 1MB 1. sup-Figure1.gif GIF image file (.gif), 104KB Figure 1 The sequence map of rice chromosome 4: cytogenetic map (Genetic and EST markers), scale (bp), clone-contigs, G+C content, NotI sites, Genes (Gene Models+/-), densities of retrotransposon and transposon, ESTs are indicated. G+C% was carried out every 40 kb. 2. sup-Figure2.gif GIF image file (.gif), 56KB Figure 2 Fibre-FISHs of the pachytene chromosome 4. The BACs used as probes wee derived from the end of the related contigs. 3. sup-Figure3.gif GIF image file (.gif), 8KB Figure 3 Distribution of repeated gene arrays on the rice chromosome4. Arrays were identified using the BLASTP program with a threshold of the E<10-20, score>200, match length > 66.7%, and similarity>90%. The histogram gives the number of clusters on the chromosome 4 containing 2 to n similar gene units. 4. sup-Figure 4.gif GIF image file (.gif), 28KB Figure 4 The BAC-contig map of Contig 5 including the centromere. (A) Markers associated with the map. (B) 10 tiled and completely sequenced Nipponbare BACs. (C) Display of the original fingerprinted CUGI contig 95. 5. sup-Figure5.gif GIF image file (.gif), 16KB Figure 5 The sequence map of the rice chromosome 4 centromeric region: cytogenetic map (Genetic and EST markers), scale (bp), clone-contigs, G+C content, NotI sites, Genes (GeneModels+/-), densites of retrotransposon and transposon, ESTs are indicated. G+C% was carried out every 40 kb. 6. sup-Figure6.gif GIF image file (.gif), 144KB Figure 6 BGI contigs match rice chromosome 4. 7. sup-Figure7.gif GIF image file (.gif), 204KB Figure 7 Comparative maps between five Arabidopsis chromosomes and rice chromosome 4. Individual chromosomes are depicted as horizontal scale lines (At1g represent the Arabidopsis chromosome1, and OSJN4 represent the Oryza sativa japonica chromosome 4). Similar genes between rice chromosome 4 and Arabidoposis are connected with coloured lines. 8. sup-Figure 8.gif GIF image file (.gif), 48KB Figure 8 Comparison of maize markers and rice chromosome 4. (a) The maize markers which have significant homology to rice chromosome 4 are indicated by coloured rectangles. (b) Maize markers are indicated by coloured lines from the inner circle (rice chromosome 4) to the outer circles of maize chromosomes 1 to 10. 9. sup-Table1.xls MS Excel spreadsheet document (.xls), 27KB Table 1 A list of RFLP markers corresponding to the position on the chromosome 4 10. sup-Table 2.xls MS Excel spreadsheet document (.xls), 69KB Table 2 A list of STS/EST markers matched to rice chromosome 4 11. sup-Table 3.xls MS Excel spreadsheet document (.xls), 18KB Table 3 The status of rice chromosome 4 gaps between contigs 12. sup-Table 4.xls MS Excel spreadsheet document (.xls), 25KB Table 4 The status of Repetitive sequence on rice chromosome 4 13. sup-Table 5.xls MS Excel spreadsheet document (.xls), 32KB Table 5 The status of tRNA gene on the chromosome 4 14. sup-Table 6.doc MS Word document (.doc), 24KB Table 6 Structural comparisons of two subspecies over 2.3 Mb 15. sup-Table 7.xls MS Excel spreadsheet document (.xls), 98KB Table 7 A list of all sequenced clones of rice chromosome 4 16. sup-Table 8.xls MS Excel spreadsheet document (.xls), 23KB Table 8 A list of the indica Guangluai 4 (GLA4) clones in the 2.3-Mb of three contiguous segments of the chromosome 4
