To explore the relationship between fruit developmental periods and the protein datasets of Alpinia oxyphylla, a label-free quantitative proteomic profiling analysis of the A. oxyphylla fruits sampled at the Earlystage, Metaphase and Advanced stage was carried out using the liquid chromatography combined with tandem mass spectrometry. A total of 19,219 peptide fragments and 4946 quantitative proteins were obtained. Annotation and enrichment analysis of these peptides and proteins were performed using the Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) databases with bioinformatics software. The results showed that the differentially expressed proteins were mainly involved in metabolic and cellular processes, cellular component organization or biogenesis and response to the stimulus. Three significantly enriched metabolic pathways were non-alcoholic fatty liver disease, vibrio cholera infection and valine, leucine and isoleucine degradation. The significantly enriched proteins were NADH dehydrogenase, putative vacuolar proton translocation ATPase and putative acyltransferase component. The proteomic profiles of the fruit samples from the Advanced and the Metaphase stages differed little, while the difference in proteomic components between the Earlystage and the Advanced groups was significant. This study should lay the theoretical foundation for the effective utilization of A. oxyphylla germplasm resource in the treatment of human diseases.

Dynamic Changes of Transcriptome and Metabolites During Ripening of Alpinia Oxyphylla Fruit (AOF)

Alpinia oxyphylla (Yizhi) is an economically valuable plant, not only used as edible fruit, but also as an important traditional medicinal material. However, there are few studies on fruit development and metabolic pathways. To elucidate the dynamic changes of metabolites and transcription levels during fruit development of A. oxyphylla, the four parts of A. oxyphylla fruit from different periods, including early fruit (EF), middle fruit (MF), late pericarp (LP) and late seed (LS) were collected. KEGG pathway analysis shows that DEGs in EF, MF, LP are involved in amino sugar and nucleotide sugar metabolism, starch and sucrose metabolism, and plant hormone signal transduction. However, at the late part of fruit development (LS), most of the DEGs between LS and LP were enriched in pyruvate metabolism, glycolysis/gluconeogenesis, tryptophan metabolism. We found that in the early and middle parts of fruit development (EF, MF), many differential metabolites were enriched in piperidine tropane and biosynthesis of secondary metabolites, pyridine alkaloid biosynthesis. In addition, important active components, such as nootkatone in A. oxyphylla fruits accumulated in the LS part, but did not show significant differences in the first three parts. Some key transcription factors that are significantly positively correlated with the maturation of AOF have also been identified. Together, our research provides new insights into the accumulation of metabolites and the dynamic changes of the transcriptome during fruit development.
