寒冷严重影响植物的生长和新陈代谢。分析冷胁迫下葡萄树幼苗代谢物变化特征，有助于了解葡萄树对胁迫的生理机制。本研究采用气相色谱-质谱联用技术系统分析了冷胁迫下葡萄球菌代谢物谱的变化特征。共稳定检测到116种差异代谢物，其中上调41种，下调75种。碳水化合物、氨基酸和有机酸的代谢物占多数。结果表明，冷胁迫对葡萄球菌幼苗差异代谢物有显著影响。葡萄球菌通过富集γ氨基丁酸、α酮戊二酸和1-酮糖等代谢物，减轻了冷胁迫对葡萄球菌的伤害程度。本研究结果为进一步分析葡萄球菌冷胁迫反应的分子和生理机制提供了基础。
Cold severely affects plant growth and metabolism. The analysis of the characteristics of metabolite variations in seedlings under cold stress can help understand the physiological mechanism of Anabasis aphylla when responding to stress. In this study, gas chromatography-mass spectrometry technology was used to systematically analyze the changing characteristics of the metabolite profiles of A. aphylla under cold stress. A total of 116 types of differential metabolites were stably detected, of which 41 were up-regulated, while 75 were down-regulated. The metabolites of carbohydrates, amino acids, and organic acids formed the majority. The results showed that cold stress had a significant impact on the differential metabolites of A. aphylla seedlings. Via enrichment of metabolites such as γaminobutyric acid, αketoglutaric acid, and 1-kestose, A. aphylla could reduce the extent of damage caused by cold stress. The results of this study provide a basis for further analysis of the molecular and physiological mechanisms of the cold stress response of A. aphylla.
