摘要

山桑子(Vaccinium myrtillus L.)是一种野生浆果,盛产于北欧。它因其营养和生物活性特性而闻名遐迩,特别是其花青素含量。然而,有关控制其他重要质量特性(如大小、硬度和风味)变化的生物系统的概述却较少受到关注。在本研究中,我们调查了山桑子四个不同成熟阶段的详细代谢组学和蛋白质组学概况,以全面了解果实成熟过程中的整体质量。通过整合全息数据集,我们揭示了山桑子成熟过程中植物激素和生理过程的新型全球调控网络。能量和初级代谢等关键生理过程与未成熟果实中赤霉素、茉莉酸和水杨酸水平的升高密切相关。相反,随着果实成熟,风味形成、细胞壁改良、种子贮藏和次生代谢等过程变得更加突出,而这些过程与赤霉酸水平的增加有关。在山桑子的发育过程中发现了乙烯生物合成增加的迹象,这就提出了关于非成熟期果实和成熟期果实分类的问题。我们的研究结果扩展了目前对果实成熟过程中发生的生理和生化过程的认识,可作为对野生和商业化种植的浆果物种进行研究的基准。此外,我们的数据还有助于优化贮藏条件和育种计划,以及未来探索浆果中的有益化合物在食品、化妆品和药物中的新应用。

Bilberry metabolomic and proteomic profiling during fruit ripening reveals key dynamics affecting fruit quality
Bilberry (Vaccinium myrtillus L.) is a wild berry species that is prevalent in northern Europe. It is renowned and well‐documented for its nutritional and bioactive properties, especially due to its anthocyanin content. However, an overview of biological systems governing changes in other crucial quality traits, such as size, firmness, and flavours, has received less attention. In the present study, we investigated detailed metabolomic and proteomic profiles at four different ripening stages of bilberry to provide a comprehensive understanding of overall quality during fruit ripening. By integrating omics datasets, we revealed a novel global regulatory network of plant hormones and physiological processes occurring during bilberry ripening. Key physiological processes, such as energy and primary metabolism, strongly correlate with elevated levels of gibberellic acids, jasmonic acid, and salicylic acid in unripe fruits. In contrast, as the fruit ripened, processes including flavour formation, cell wall modification, seed storage, and secondary metabolism became more prominent, and these were associated with increased abscisic acid levels. An indication of the increase in ethylene biosynthesis was detected during bilberry development, raising questions about the classification of non‐climacteric and climacteric fruits. Our findings extend the current knowledge on the physiological and biochemical processes occurring during fruit ripening, which can serve as a baseline for studies on both wild and commercially grown berry species. Furthermore, our data may facilitate the optimization of storage conditions and breeding programs, as well as the future exploration of beneficial compounds in berries for new applications in food, cosmetics, and medicines.

期刊介绍: Physiologia Plantarum is an international journal committed to publishing the best full-length original research papers that advance our understanding of primary mechanisms of plant development, growth and productivity as well as plant interactions with the biotic and abiotic environment. All organisational levels of experimental plant biology – from molecular and cell biology, biochemistry and biophysics to ecophysiology and global change biology – fall within the scope of the journal. The content is distributed between 5 main subject areas supervised by Subject Editors specialised in the respective domain: (1) biochemistry and metabolism, (2) ecophysiology, stress and adaptation, (3) uptake, transport and assimilation, (4) development, growth and differentiation, (5) photobiology and photosynthesis.
