基于 SPE-UPLC 的单花生 （Arachis spp.） 中黄曲霉毒素和二苯乙烯类植物抗毒素的无损定量分析种子

Executive Industry Relevance

Quantitative, non-destructive SPE-UPLC analysis of aflatoxins and stilbenoid phytoalexins in single peanut seeds enables high-throughput screening of genetic resistance to fungal contamination. This capability addresses a critical bottleneck in trait discovery and germplasm triage for crop improvement pipelines. The method supports predictive confidence in selecting disease-resistant lines, directly impacting translational continuity from discovery to pre-breeding.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables holistic profiling of individual seeds for both mycotoxin and phytoalexin content.
• Supports functional validation of resistance traits in wild and cultivated germplasm.
• Facilitates mechanistic de-risking by linking chemical defense markers to genetic backgrounds.
• Improves predictive confidence in identifying resistance loci for downstream breeding.

Screening & Assay Development

• Delivers validated, quantitative outputs for aflatoxin and phytoalexin levels in single seeds.
• Standardizes sample preparation and UPLC quantification for reproducible screening.
• Enables scalable, medium-throughput analysis essential for large germplasm collections.
• Prepares robust biological systems for reliable compound or trait evaluation.

Translational & Preclinical Research

• Aligns chemical phenotyping with genetic and transcriptomic data for translational trait mapping.
• Supports continuity from early discovery through pre-breeding validation of resistance traits.
• Reduces risk in advancing candidate lines by providing quantitative, mechanistic evidence of resistance.
