我们展示了一种使用超高效液相色谱法定量单个花生种子中黄曲霉毒素和二苯乙烯类植物抗毒素的中等通量方法。该方法专为分析受产黄曲霉菌属攻击的野生花生物种而开发。

研究范围是开发一种定量数千种花生种子中黄曲霉毒素和防御性植物抗毒素的方法,用于探索野生花生种质,鉴定对曲霉菌具有抗性的物种,并确定和表征对这种真菌病原体的遗传抗性的新来源。我们的研究小组发现,鉴定不积累黄曲霉毒素的花生种质最有前途的方法是对每粒种子进行整体分析,包括其转录组学、基因组学、植物抗毒素和霉菌毒素谱。我们开发了野生和栽培花生种子分析方案,这意味着使用单个种子的 1/4 进行化学分析,开发高通量方法,以有效挑战、提取和准确定量花生种子样品中的植物抗毒素。

我们发现了许多花生植物抗毒素,并开发了高效且廉价的黄曲霉毒素分析方法,以及用于筛选黄曲霉毒素积累减少或没有黄曲霉毒素积累的花生种质。这些方法包括基因分型和种子活力测定。
