Pollen metabolomics using Arabidopsis thaliana: Comparison of pollen at mature, hydration and germination stage
Ontology highlight
ABSTRACT: In this study, we investigated the differential metabolic pathway enrichment among mature, hydrated, and germinated pollen using untargeted metabolomics analysis. Integration of publicly available transcriptome with presented metabolome data revealed starch and sucrose metabolism was significantly increased during pollen hydration and germination. The alterations in central metabolism focusing on sugar, fatty acids, and lipids were analyzed in detail. Several metabolites, including palmitic acid, oleic acid, linolenic acid, quercetin, luteolin/kaempferol, and γ-aminobutyric acid (GABA), were elevated in the hydrated pollen, suggesting a potential role in activating pollen tube emergence. The metabolite levels of mature, hydrated, and germinated pollen, presented in this work provide insights on the molecular basis of pollen germination.
