Litchi Mutagenesis Data: Pingyangmycin-Induced Somatic Mutations and Regenerated Plants

A research document details the establishment of a pingyangmycin-induced mutagenesis system for litchi using in vitro-cultured embryogenic callus. The study identified 307,629 high-quality somatic mutations in treated callus and over 1.2 million variants in regenerated mutant lines, with mutation frequencies exceeding typical EMS-induced rates. The document was authored by Guo Wang and last updated on 2026-05-08.

Use Cases

• Analyzing mutation spectra and frequencies based on whole-genome resequencing data from mutagen-treated callus.
• Studying the relationship between chemical dosage and cell viability based on gradient concentration treatments.
• Identifying genetic resources for functional genomics based on the collection of regenerated mutant plant lines.
• Comparing mutagenic efficacy between pingyangmycin and other agents like EMS based on reported mutation rates.

Strengths

• Reports specific mutation counts: 307,629 high-quality somatic mutations in callus and over 1.2 million variants in regenerated plants.
• Quantifies mutation frequencies: 1.8×10⁻⁴ and 1.4×10⁻⁴ per site for two cultivars, which are noted as exceeding typical rates.
• Describes detailed experimental parameters: gradient concentrations of pingyangmycin from 0–40 mg/L and their effects.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary file is a DOCX document (325.6 KB), which may not contain structured, machine-readable data tables.
