Intraspecific Plastome Diversity Across Seed Plants and Soybean Domestication

6,484 plastid genomes from 17 seed plant species reveal extensive intraspecific variation, challenging assumptions of plastome conservation. The dataset includes a pangenome analysis of 2,306 soybean accessions, showing erosion of plastomic diversity due to maternal bottlenecks during domestication. Columns suggest data on hypervariable regions and lineage-specific mutational pressures.

Use Cases

• Analyzing intraspecific plastome variation patterns across different seed plant lineages
• Investigating the impact of domestication bottlenecks on plastid genetic diversity using soybean accessions
• Identifying hypervariable regions within plastomes for use as multi-locus markers
• Assessing cytonuclear incompatibility by matching plastid and nuclear genomic data
• Exploring wild crop relatives as a genetic resource for organellar selection in crop improvement

Strengths

• Contains 6,484 plastid genomes, a large-scale sample for population-level analysis
• Includes 2,306 soybean accessions, forming the largest plastid pangenome to date
• Explicitly examines 17 representative seed plant species for comparative study

Limitations

• Column names and specific data structure are not provided in the source metadata
• The dataset size is given (302987054 bytes), but the exact row count is unknown
• Relies on inferred data types from descriptions rather than explicit column definitions
