Comparative Mitochondrial Genomes of Curcuma longa and Curcuma kwangsiensis

Yunyi Zhou published this dataset on 2026-04-15. It contains comparative genomic analysis results for the complete mitochondrial genomes of two medicinal Curcuma species, C. longa and C. kwangsiensis. The data includes metrics on genome size, GC content, gene counts, repeat landscapes, and evolutionary selection pressures.

Use Cases

• Analyzing mitochondrial genome structural plasticity based on reported synteny comparisons and repeat landscapes.
• Studying evolutionary selection pressures based on reported purifying and episodic positive selection on specific genes.
• Investigating cross-organelle gene transfer based on reported plastid-derived fragment incorporation.
• Comparing codon usage bias and RNA editing patterns between species based on described A/U bias and C-to-U conversions.

Strengths

• Genome size metrics are explicitly provided (7.66 Mb for C. longa, 7.96 Mb for C. kwangsiensis).
• Specific gene counts and variations are detailed (39 core genes, pseudogenization of sdh3 and rpl10).
• Quantitative repeat analysis is included (3,059 dispersed repeats in a specific size range for C. kwangsiensis).
• Phylogenetic analysis results are provided (maximum bootstrap support of 100, substitution rate of 0.004 per site).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (227.5 KB), indicating it likely contains summary analysis rather than raw sequence data.
