Camellia Yungkiangensis Chloroplast Genomes and Biochemical Traits

Sihui Liang published a study on figshare in 2026 analyzing 162 germplasm samples of caffeine-free Camellia yungkiangensis from Guizhou, China. The work includes complete chloroplast genome sequences for two accessions, revealing lengths of 156,872 bp and 156,892 bp, and biochemical profiles confirming universal caffeine absence. The data provides genomic and biochemical foundations for breeding specialty caffeine-free teas.

Use Cases

• Phylogenetic analysis of Camellia species based on chloroplast genome sequences
• Identification of molecular markers for plant breeding based on unique SSR repeats
• Biochemical profiling of tea germplasms based on catechin and alkaloid content data
• Comparative genomics of caffeine-free tea plants based on chloroplast genome architecture

Strengths

• Complete chloroplast genome sequences for two accessions with precise lengths (156,872 bp and 156,892 bp) and 133 annotated genes.
• Biochemical data from 162 germplasm samples confirming universal caffeine absence and quantifying theobromine (average 4%) and catechins.
• Includes identification of unique molecular markers, such as a hexameric SSR repeat present in one accession.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a DOCX document, which may require parsing to extract structured data.
