Aflatoxin contamination of maize is a leading threat to health in Guatemala. This contamination is the result of infection from and has been effectively reduced in other countries through application of nonaflatoxigenic, indigenous strains of . We collected 82 maize samples from throughout Guatemala in two years and isolated 272 from these samples, including 126 unique genotypes. We provide here a phenotypic and simple sequence repeat (SSR)-based genotypic description of these isolates, as well as an analysis of the diversity of this population. High levels of genetic diversity were observed with the nonaflatoxigenic isolates in this study, but this information contributes to the development of indigenous aflatoxin biocontrol products.
玉米中的黄曲霉毒素污染是危地马拉健康面临的主要威胁。这种污染是由[某种感染源]感染所致，并且在其他国家通过应用非产黄曲霉毒素的本地[某种菌株]已得到有效减少。我们在两年内从危地马拉各地收集了82个玉米样本，并从这些样本中分离出272株[某种菌株]，其中包括126个独特的基因型。我们在此提供这些分离株基于表型和简单序列重复（SSR）的基因型描述，以及对该群体多样性的分析。本研究中观察到非产黄曲霉毒素分离株具有高水平的遗传多样性，这些信息有助于开发本地黄曲霉毒素生物防治产品。
