Supplementary Data 2 and 3

This dataset contains raw data describing the co-expression regulatory network between metabolomics and transcriptomics in the study titled "Unraveling the regulatory network of barley grain metabolism through the integrative analysis of multiomics and mQTL". The dataset retains results meeting the thresholds of Pearson’s correlation coefficient (PPC) > 0.8 and p-value < 0.01. - Supplementary Data 2: Pearson's correlations between genes and annotated metabolites (PPC > 0.8, p < 0.01). - Supplementary Data 3: Pearson's correlations between genes and unknown metabolites (PPC > 0.8, p < 0.01).  Data Fields - Gene ID: Gene identifiers from the barley Morex v3 reference genome. - Peak number: Unique identifier for metabolites. - Compound: Name of the annotated metabolite (applies to Supplementary Data 2 only). - Class: Classification category of the metabolite. - Correlation_coefficient: Pearson’s correlation coefficient between metabolite abundance and gene expression levels. - pvalue: Results of the two-tailed t-test for null hypothesis testing .  The dataset provides a comprehensive resource for exploring gene-metabolite regulatory interactions in barley grain metabolism.
