Camellia Yungkiangensis Chloroplast Genomes and Biochemical Profiles from Guizhou, China

A 2026 study by Sihui Liang analyzes 162 germplasm samples from five populations of the caffeine-free tea plant Camellia yungkiangensis in Guizhou, China. The dataset includes complete chloroplast genome sequences for two distinct accessions and biochemical profiles measuring catechins and alkaloids. It 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 simple sequence repeats (SSRs).
• Comparative analysis of biochemical profiles, including caffeine, theobromine, and catechin levels.
• Studying the genetic divergence of wild tea plant resources from cultivated varieties.

Strengths

• Includes complete chloroplast genome sequences for two distinct accessions with lengths of 156,872 bp and 156,892 bp.
• Biochemical analysis covers 162 germplasm samples from five distinct populations, confirming universal caffeine absence.
• Provides specific quantitative measurements, such as an average theobromine content of 4% and catechin levels above 6%.

Limitations

• Dataset is very small (47.5 KB), indicating limited scope, likely containing summary results rather than raw sequencing data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the five sampled populations in Guizhou, China.
