Citrus fruits are valued not only for their nutritional benefits but also for their rich phytochemical content. Metabolomics has emerged as a comprehensive technique for assessing the chemical composition of fruits. The botanical connection between leaves, flowers, and fruits is reflected in both their structure and chemical composition, particularly in the flow of nutrients between plant organs. We introduced a new logarithm ratio-based approach to compare metabolite profiles between fruits and leaves. We hypothesize that this method allows for the analysis of multiple citrus metabolomic profiles to reveal known and novel correlation patterns, reflecting the dynamic connections between metabolic sources. To test this hypothesis, we leveraged comprehensive leaf metabolomic profiles from over 200 accessions in the Givaudan Citrus Variety Collection and reviewed published metabolomics data for fruits and juices of matching citrus types. By employing logarithm-transformed metabolic ratios within each dataset, we accounted for systematic differences across metabolomic platforms, achieving an unbiased analysis.
柑橘类水果不仅因其营养价值而受到重视，还因其丰富的植物化学成分而备受关注。代谢组学已成为评估水果化学成分的一种综合技术。叶子、花朵和果实之间的植物学联系在它们的结构和化学成分中都有所体现，特别是在植物器官之间的营养物质流动方面。我们引入了一种基于对数比率的新方法来比较果实和叶子之间的代谢物谱。我们假设这种方法能够分析多个柑橘代谢组学谱，以揭示已知和新的相关模式，反映代谢源之间的动态联系。为了验证这一假设，我们利用了来自奇华顿柑橘品种收集库中200多个种质的全面叶片代谢组学谱，并回顾了已发表的匹配柑橘类型的果实和果汁的代谢组学数据。通过在每个数据集中采用对数转换后的代谢比率，我们考虑了代谢组学平台之间的系统差异，实现了无偏分析。
