Phenolic Compounds and GWAS Results for 118 Wild Bilberry Genotypes

A study from 2026 by Carlos-Eduardo Narváez-Cuenca profiles anthocyanin and nonanthocyanin phenolic compounds in the wild bilberry Vaccinium meridionale Swartz. It includes data from 118 fruit genotypes, control fruit, and leaf samples, identifying 24 compounds via RP-UHPLC-DAD and ESI-QTOF-MS/MS. Genome-wide association studies using 16,709 SNPs across 69 genotypes identified 40 significant quantitative trait nucleotides linked to seven phenolic compounds.

Use Cases

• Identify genetic markers for phenolic compound biosynthesis based on the 40 significant QTNs discovered.
• Compare phenolic profiles between fruit and leaf tissues based on the quantified compounds like chlorogenic acid and cyanidin-3-O-galactoside.
• Study the genetic architecture of specific compounds like caffeoyl arbutin or quercetin derivatives using the GWAS results and candidate genes (e.g., MYB, bHLH).

Strengths

• Quantitative data for 24 identified phenolic compounds with concentration ranges provided (e.g., chlorogenic acid 223.5–2539.8 mg/100g DW in fruit).
• Genetic analysis is based on 16,709 high-quality SNPs across 69 genotypes, identifying 40 significant QTNs.
• Compound identification used two analytical methods: RP-UHPLC-DAD and RP-UHPLC with ESI-QTOF-MS/MS.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small in file size (32.1 KB), indicating limited scope.
