Population Genomics of Invasive Solanum Rostratum Across 30 Chinese Populations

A collection of genome-wide single nucleotide polymorphisms (SNPs) from 261 individuals of the invasive herb Solanum rostratum. It was created by Lifen Hao to analyze genetic structure and dispersal sources across 30 populations in northern China, with data last updated in March 2026.

Use Cases

• Analyze genetic structure and assign individuals to the seven ancestral gene pools (P1–P7) inferred from SNP data.
• Trace gene flow patterns and dispersal networks to identify source populations like those in Zhangjiakou (ZJ) and Chifeng (CF).
• Compare genetic diversity metrics (Ne, Ho, He, Fis, π) between early-invaded and newly invaded populations to study founder effects.
• Reconstruct phylogenetic relationships among the seven major monophyletic groups (A–G) resolved from the SNP data.
• Categorize populations as early-invaded, mid-invaded, or newly invaded based on county-level invasion records to study invasion history.

Strengths

• Includes genomic data from 261 individual samples, providing a solid basis for population-level analysis.
• Covers 30 distinct populations across northern China, enabling spatial genetic and dispersal studies.
• Data is structured around testing specific hypotheses regarding anthropogenic dispersal hubs and asymmetric gene flow.
• Released under a permissive CC BY 4.0 license, facilitating reuse and redistribution.

Limitations

• The dataset is relatively small at 8.3 MB, which may limit the complexity of genomic analyses possible.
• Specific file formats, column structures, and row counts within the ZIP archive are unknown, requiring initial exploration.
• The data is focused on a single invasive species in a specific region, limiting generalizability to other taxa or geographies.
