Molecular Evolution of Floral Development Genes in Two Spiral Ginger Species

A 5.1 MB supplementary document published on figshare in March 2026 by Deivid Almeida de Jesus. It presents a comparative analysis of key floral developmental genes in two closely related spiral gingers, Costus bracteatus and Costus zingiberoides, which have contrasting bee and hummingbird pollination syndromes. The analysis uses genome assemblies, phylogenetic inference, and protein modeling to investigate the molecular basis of floral adaptation.

Use Cases

• Identifying signatures of positive selection in floral developmental genes based on the described phylogenetic and selection analyses.
• Comparing protein structural differences between species based on the mentioned in silico protein modeling and domain comparisons.
• Investigating the genetic basis of divergent pollination syndromes based on the comparative study of two Costus species.
• Analyzing lineage-specific divergence in genes like AGL6 and CUC-like based on the findings highlighted in the description.

Strengths

• Dataset is licensed under CC-BY-4.0, allowing for broad reuse and redistribution.
• Analysis is focused on a specific, well-defined biological comparison between two closely related species with distinct pollination syndromes.
• The description details specific analytical methods used, including genome assemblies, phylogenetic inference, and protein modeling.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is a 5.1 MB DOCX file, which is a small and potentially unstructured text document rather than a primary data table.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
