Analysis of metabolites and expression characteristics of sulfur metabolism related genes in 'Nanou' garlic and common garlics based on LC-MS

摘要

In this study, LC-MS (liquid chromatography-mass spectrometry) was used to detect the differences in the whole metabolism group and the difference in the content of partial sulfur metabolites in 'Nanou' garlic and common garlic. Meanwhile, 6 genes related to the sulfur metabolism in garlic were analyzed by qRT-pcr. The results showed that 'Nanou' was significantly different from the common garlic in the metabolic groups and the content of sulfur metabolites. The content of allicin and alliin in 'Nanou' was significantly lower than that of common garlic, and the difference in the expression of genes encoding related enzymes was in accordance with the content of sulfur metabolites.
