摘要：
Cashew nut is a popular food around the world. The high-resolution profiles and dynamics of metabolomes in cashew fruits are poorly understood till now. In this study, we analyzed the temporal metabolome of cashew nut via a non-targeted method based on UHPLC-Q-Exactive-MS, and analyzed that of cashew apple via a widely targeted method based on UHPLC-QTRAP-MS/MS (MRM). Furthermore, we performed integrative analyses of temporal metabolome and transcriptome data, characterized the accumulation of specific metabolites, and identified the transcriptional changes during cashew fruit development. Specifically, we found that phosphati-dylinositol species were the predominant fractions in the unsaturated glycerophospholipids, and we identified a transcription factor that was the potential regulator of phosphatidylinositol biosynthesis. Analysis of cashew apple revealed metabolic genes and transcription factors involved in sugar biosynthesis. Taken together, our results provide insights into metabolic networks during cashew fruit development and generate a valuable resource for further cashew breeding studies.
