摘要

黄酮类化合物是植物专门代谢产物的一个多样化群体,在饮食健康和炎症反应方面也有讨论。大量研究表明,类黄酮在植物适应低温或强光等非生物因素的过程中发挥着核心作用,但其结构和功能的多样性往往阻碍了对其机理的详细了解。参与生物合成和贮藏的亚细胞区系不同,进一步增加了分析类黄酮代谢的复杂性。在本研究中,拟南芥叶片组织的非水分馏与代谢组学和蛋白质组学分析相结合,揭示了类黄酮缺乏对低温适应过程中亚细胞代谢的影响。在为期两周的冷适应期的前三天,类黄酮缺乏会影响丙酮酸、柠檬酸和谷氨酸的代谢,这表明类黄酮在稳定C/N代谢和光合作用方面发挥作用。此外,还发现四氢叶酸代谢受到影响,这对光呼吸途径的蛋白质组有显著影响。在冷适应后期,黄酮类化合物的缺乏会影响蛋白质的稳定性、折叠和蛋白酶体降解,从而导致两种突变体的蛋白质总量显著下降。总之,这些研究结果表明,类黄酮代谢在植物冷适应的早期和晚期阶段发挥着不同的作用,并对在不断变化的环境中建立新的蛋白质平衡做出了重要贡献。

Insights into physiological roles of flavonoids in plant cold acclimation.

Flavonoids represent a diverse group of plant specialised metabolites which are also discussed in the context of dietary health and inflammatory response. Numerous studies have revealed that flavonoids play a central role in plant acclimation to abiotic factors like low temperature or high light, but their structural and functional diversity frequently prevents a detailed mechanistic understanding. Further complexity in analysing flavonoid metabolism arises from the different subcellular compartments which are involved in biosynthesis and storage. In the present study, non-aqueous fractionation of Arabidopsis leaf tissue was combined with metabolomics and proteomics analysis to reveal the effects of flavonoid deficiencies on subcellular metabolism during cold acclimation. During the first 3 days of a 2-week cold acclimation period, flavonoid deficiency was observed to affect pyruvate, citrate and glutamate metabolism which indicated a role in stabilising C/N metabolism and photosynthesis. Also, tetrahydrofolate metabolism was found to be affected, which had significant effects on the proteome of the photorespiratory pathway. In the late stage of cold acclimation, flavonoid deficiency was found to affect protein stability, folding and proteasomal degradation, which resulted in a significant decrease in total protein amounts in both mutants. In summary, these findings suggest that flavonoid metabolism plays different roles in the early and late stages of plant cold acclimation and significantly contributes to establishing a new protein homeostasis in a changing environment.

期刊介绍: Publishing the best original research papers in all key areas of modern plant biology from the world"s leading laboratories, The Plant Journal provides a dynamic forum for this ever growing international research community. Plant science research is now at the forefront of research in the biological sciences, with breakthroughs in our understanding of fundamental processes in plants matching those in other organisms. The impact of molecular genetics and the availability of model and crop species can be seen in all aspects of plant biology. For publication in The Plant Journal the research must provide a highly significant new contribution to our understanding of plants and be of general interest to the plant science community.
