| 英文摘要 | The complexity of polyploid Saccharum genomes hindered progress of genome research and crop improvement in sugarcane. To understand their genome structure, transcriptomes of 59 F-1 individuals derived from S. officinarumLA Purple and S. robustum Molokai 5829 (2n = 80, x = 10 for both) were sequenced, yielding 11 157 and 8998 SNPs and 83 and 105 linkage groups, respectively. Most markers in each linkage group aligned to single sorghum chromosome. However, 71 interchromosomal rearrangements were detected between sorghum and S. officinarum or S. robustum, and 24 (33.8%) of them were shared between S. officinarum and S. robustum, indicating their occurrence before the speciation event that separated these two species. More than 2000 gene pairs from S. spontaneum, S. officinarum and S. robustum were analysed to estimate their divergence time. Saccharum officinarum and S. robustum diverged about 385 thousand years ago, and the whole-genome duplication events occurred after the speciation event because of shared interchromosomal rearrangements. The ancestor of these two species diverged from S. spontaneum about 769 thousand years ago, and the reduction in basic chromosome number from 10 to 8 in S. spontaneum occurred after the speciation event but before the two rounds of whole-genome duplication. Our results proved that S. officinarum is a legitimate species in its own right and not a selection from S. robustum during the domestication process in the past 10 000 years. Our findings rejected a long-standing hypothesis and clarified the timing of speciation and whole-genome duplication events in Saccharum. |
