Repeatome Landscape in the Saccharum Complex Across 30 Genotypes

30 genotypes from nine Saccharum species, modern cultivars, and related genera were analyzed for repetitive DNA content. The dataset, created by Nina Reis Soares and last updated in May 2026, reports repetitive DNA percentages ranging from 42.5% to 59.7%, with LTR retrotransposons as the dominant fraction.

Use Cases

• Analyze the correlation between repeat abundance and genome size based on the described strong relationship
• Compare lineage-specific repeat diversification based on the reported interspecific variation in Ty3 and Ty1 LTR-RTs
• Identify taxon-specific satellite DNAs based on the description of their abundance
• Reconstruct phylogenetic relationships based on repeat-based phylogenies mentioned in the results

Strengths

• Data covers 30 genotypes across nine Saccharum species and related genera
• Repetitive DNA content quantified with specific percentages (42.5% to 59.7%)
• Analysis includes structural examination of LTR-RTs in three fully assembled genomes

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
