This study compared the taste and nutrition related metabolites of wild blueberry (WB) and cultivated blueberry (CB) varieties in Northeast China based on widely targeted metabolomics. A total of 858 metabolites were identified, of which 254 showed significant differences. 16 carbohydrates were significantly higher in CBs than in WB, while 11 organic acids were the opposite. Otherwise, 24 flavonoids have significant advantages in WB, while amino acids and their derivatives have specific advantages in WB and CBs, which may determine the differences in fruit aroma and taste between the two. In addition, we found that "alanine, aspartate, and glutamate metabolism" is the most critical differential metabolic pathway among WB and CBs; fumaric acid, succinic acid, L-glutamic acid, and L-argininosuccinate are considered key biomarkers for distinguishing WB from CBs. This study will provide a reference for Chinese blueberries' scientific introduction of seeds, comprehensive development and effective differentiation of related products.
本研究基于广泛靶向代谢组学比较了中国东北地区野生蓝莓（WB）和栽培蓝莓（CB）品种的风味和营养相关代谢产物。共鉴定出858种代谢产物，其中254种存在显著差异。16种碳水化合物在栽培蓝莓中的含量显著高于野生蓝莓，而11种有机酸则相反。此外，24种黄酮类化合物在野生蓝莓中具有显著优势，而氨基酸及其衍生物在野生蓝莓和栽培蓝莓中均具有特定优势，这可能决定了两者果实香气和风味的差异。此外，我们发现“丙氨酸、天冬氨酸和谷氨酸代谢”是野生蓝莓和栽培蓝莓之间最关键的差异代谢途径；富马酸、琥珀酸、L-谷氨酸和L-精氨琥珀酸被认为是区分野生蓝莓和栽培蓝莓的关键生物标志物。本研究将为中国蓝莓种子的科学引进、相关产品的综合开发和有效区分提供参考。
