Litchi Mutagenesis Data: Pingyangmycin-Induced Somatic Mutations from Embryogenic Callus

307,629 high-quality somatic mutations were identified in litchi embryogenic callus treated with pingyangmycin. The dataset, authored by Guo Wang and last updated in May 2026, contains whole-genome resequencing results from treated callus and 40 regenerated mutant lines, reporting mutation frequencies of 1.8×10⁻⁴ and 1.4×10⁻⁴ per site.

Use Cases

• Analyzing mutation spectra and frequencies induced by pingyangmycin based on the reported 255,721 SNVs and 51,908 indels
• Studying the relationship between mutagen dosage and cell viability based on the gradient concentration treatments from 0–40 mg/L
• Comparing mutagenic efficacy between chemical agents based on the reported mutation rates exceeding typical EMS-induced rates
• Investigating leaf morphological variation in regenerated mutant plants based on the described substantial diversification

Strengths

• Reports specific mutation counts: 307,629 high-quality somatic mutations, with 255,721 SNVs and 51,908 indels
• Provides detailed mutagenesis parameters: gradient concentrations of pingyangmycin from 0–40 mg/L
• Includes data from regenerated mutant lines: 40 lines from two cultivars ('Feizixiao' and 'Lingnan15') with over 1.2 million variants each

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The 21.7 KB file size suggests the dataset is a document summarizing results rather than containing the raw sequencing data
