Comparative Mitochondrial Genomes of Curcuma longa and Curcuma kwangsiensis

Two complete mitochondrial genomes, each over 7.6 Mb, sequenced from the medicinal plants Curcuma longa and Curcuma kwangsiensis. The dataset, uploaded by Yunyi Zhou in April 2026, reveals structural differences, conserved genes, and species-specific evolutionary dynamics. It includes analyses of genome size, GC content, gene duplication, RNA editing, and phylogenetic relationships.

Use Cases

• Comparative genomic analysis based on the assembled 7.66 Mb and 7.96 Mb mitochondrial genomes.
• Studying codon usage bias based on the described strong A/U bias in synonymous positions.
• Investigating RNA editing patterns based on the described extensive C-to-U conversions in membrane-associated proteins.
• Analyzing repeat element landscapes based on the identified 3,059 dispersed repeats in C. kwangsiensis.
• Phylogenetic reconstruction based on the described 100% bootstrap support for the monophyletic clade.

Strengths

• Complete mitochondrial genome assemblies for two species with precise sizes of 7.66 Mb and 7.96 Mb.
• Includes detailed comparative metrics such as GC content (43.7–43.9%) and counts of core protein-coding genes (39).
• Analysis includes specific repeat counts, such as 3,059 dispersed repeats in C. kwangsiensis.
• Phylogenetic analysis has high statistical support with a maximum bootstrap value of 100.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is small (59.4 KB), suggesting it contains summary or analysis results rather than raw sequence data.
• Data may reflect bias inherent to the specific two species studied, limiting generalizability across the genus.
