黑木耳不同颜色子实体的比较代谢组学分析
Comparative metabolome analysis of different color fruiting bodies of Auricularia heimuer
摘要
Abstract
[Objective]The study aimed to investigate the metabolite disparity in fruiting bodies of Auricularia heimuer with different colors,and to provide a reference for the subsequent research on the color difference of A.heimuer and the development and utilization of products.[Method]Untargeted metabolomics of the fruiting bodies with different colors from a same variety was studied by high performance liquid chromatography-mass spectrometry.[Result]A total of 1624 metabolites were identified in both yellow(HY)and black(HH)fruiting bodies.A total of 372 metabolites exhibited significant differences,with 347 up-regulated and 25 down-regulated.These varied metabolites en-compassed amino acids and peptides,shikimates and phenylpropanoids,alkaloids,terpenoids,etc.,with terpenoids being the predominant group(91).Notably,the fruiting bodies of A.heimuer contained the highest levels of fatty acids,amino acids and peptides,with HY exhibi-ting notably higher values compared to HH.Different metabolites were predominantly enriched in biosynthesis of amino acids,ABC transporter and other pathways,with biosynthesis of amino acids pathway predominantly.Additionally,the relative content of common amino acids except phenylalanine was significantly higher in HY than that in HH,with tyrosine standing out as the most notable.[Conclusion]Amino acids and peptides,shikimates and phenylpropanoids,alkaloids,terpenoids are significantly different in different color fruiting bodies of A.heimuer,which may be the material basis affecting the formation of color.关键词
