Separation and Identification of Metabolites and Metabolic Pathway Analysis in Different Vegetable Sweet Potato
摘要
Abstract
To study the effects of metabolites on the growth and development of vegetable sweet potato,the stem tips of sweet potatoes were as materials,and liquid chromatograph-mass spectrometer(LC-MC)was employed to identify and separate metabolic products of 6 sweet potato cultivars including Nanningcai,Fucaishu 18,Guicaishu 1,Guicaishu 2,Fushu 7-6 and Tainong 71.The differences of metabolic pathways were further discussed.The results revealed a total of 4 210 differential metabolites were detected across 6 sweet potato cultivars,with 2 229 up-regulated and 1 981 down-regulated,which showed that there were significant differences among different sweet potato cultivars.The primary metabolic pathways associated with differential metabolism included primary bile acid biosynthesis,indole alkaloid biosynthesis,flavonoid and flavonol biosynthesis and tryptophan metabolism.The accumulation of differential metabolites and their respective metabolic pathways among different varieties had significant differences.Consequently,it was hypothesized that the differences in both the accumulation and metabolism of these metabolites played a crucial role in sweet potato quality.Above results provided reliable basis for understanding the mechanisms of differences on quality of sweet potato.关键词
