Tef (Eragrostis tef), is a gluten-free orphan cereal, crop of nutritional and economical significance. Here we used untargeted metabolomics to survey metabolite variation in 14 diverse tef accessions at 15-days post germination. Tef genotypes were classified into four metabolomic groups where variation was linked to flavones and flavonols. Further analysis on white seeded accessions shows variation related to sucrose and important vitamins, nicotinamides (vitamin B3) riboflavin (vitamin B2) and folate (vitamin B9). Coloured seeded accessions showed variation in metabolism related to amino acid and sugars. This study highlights the potential of metabolomics in exploring the nutritional traits in tef.
埃塞俄比亚画眉草（画眉草）是一种不含麸质的孤儿谷物，具有重要的营养和经济意义。在这里，我们使用非靶向代谢组学方法在发芽后 15 天调查了 14 个不同埃塞俄比亚画眉草品种的代谢物变化。埃塞俄比亚画眉草基因型分为四个代谢组群，其变化与类黄酮和黄酮醇有关。对白色种子品种的进一步分析表明，变异与蔗糖和重要维生素、烟酰胺（维生素 B3）、核黄素（维生素 B2）和叶酸（维生素 B9）有关。有色种子品种表现出与氨基酸和糖代谢相关的变化。本研究强调了代谢组学在探索埃塞俄比亚画眉草营养特性方面的潜力。
