Fruit are susceptible to quality loss and deterioration after harvest due to high metabolic and physiological activities. Over the last four decades various postharvest treatments have ensured maintenance of quality, control of diseases or decay by slowing down the postharvest ripening and senesce. The fruit quality change during postharvest however, has been mostly explored using physicochemical characteristics. Considering the complexity of fruit physiology and metabolism, the application of omics techniques could aid the in-depth analysis and understanding of fruit quality change during postharvest treatment. Therefore, this review presents recent information on the application of integrated omics (transcriptomics, proteomics, and metabolomics) in postharvest research, with an overview on fruit quality and safety. Trends in omics data analysis for fruit during postharvest handling was highlighted. The role of integrated omics in improving our understanding of fruit response during natural postharvest progression (towards decay) during storage, as well as in case of induced responses due to the application of biocontrols was discussed. The article concluded with the outlooks of future studies on the application of integrated omics as the catalyst for innovative postharvest solutions.
由于收获后果实具有高代谢和生理活性，其易发生品质损失和变质。在过去的四十年里，各种采后处理通过减缓采后成熟和衰老来确保果实品质的维持，控制病害或腐烂。然而，采后果实品质变化大多是利用物理化学特性进行研究的。考虑到果实生理和代谢的复杂性，组学技术的应用有助于深入分析和理解采后处理过程中的果实品质变化。因此，本综述介绍了整合组学（转录组学、蛋白质组学和代谢组学）在采后研究中的最新应用信息，并概述了果实品质与安全。重点介绍了采后处理过程中果实组学数据分析的趋势。讨论了整合组学在增进我们对果实采后自然进程（走向腐烂）以及因应用生物防治措施而产生的诱导反应过程中果实反应的理解方面所起的作用。文章最后展望了整合组学作为创新采后解决方案催化剂的未来研究前景。
