Chinese cabbage is a nutrients-rich vegetable with diverse leaf colors. Here, we used widely-targeted metabolomics technology to study the metabolic responses of three Chinese cabbage varieties with representative leaf colors after blue light treatment. The inner leaf color of orange varieties 20S530 and 15S1094 changed from yellow to golden yellow, while no visible color change occurred in the common variety 14S23 after the treatment. A total of 844 metabolites were measured from the leaf samples of these three varieties in a time course study after short term blue light treatment, with kaempferol-4'-O-glucoside, isoquercitrin, hyperin, arbutin, sulforaphane as enriched nutritional metabolites. Orange Chinese cabbage varieties showed additional nutrition enhancement after the treatment. This study is the first to explore the global metabolic responses of Chinese cabbage after blue light treatment, and our findings provided valuable insights on how to effectively use lighting conditions to enhance specific groups of nutrients in vegetables.
白菜是一种营养丰富的蔬菜，具有多种叶色。在这里，我们使用广泛靶向的代谢组学技术研究了三种具有代表性叶色的白菜品种在蓝光处理后的代谢反应。橙色品种 20S530 和 15S1094 的内叶颜色从黄色变为金黄色，而普通品种 14S23 在处理后没有明显的颜色变化。在短期蓝光处理后，从这三个品种的叶片样本中进行时间过程研究，共测量了 844 种代谢物，其中山奈酚-4'-O-葡萄糖苷、异槲皮苷、金丝桃苷、熊果苷、萝卜硫素作为富含营养的代谢物。橙色白菜品种在处理后表现出额外的营养增强。这项研究首次探索了白菜在蓝光处理后的全局代谢反应，我们的发现为如何有效利用光照条件来增强蔬菜中特定营养物质组提供了有价值的见解。
