Figure 5 Analysis of pvalue histogram by enrichment of differential gene and differential metabolite KEGG
1.6 Analysis of O2PLS
All the differential genes and metabolites were selected to establish O2PLS model, and the important variables
influencing the other omics were screened out. Due to the large number of genes and metabolites, only the top 10
genes and the top 10 metabolites that have great influence on the other omics are listed. The results are shown in
Table 1. The top ten metabolites of differentially expressed genes were mainly glycosides, amino acids and
phenolic acids. The results showed that the expression regulation of differential genes between male sterile lines
and fertile lines resulted in significant differences in transcriptome, which resulted in significant regulation of
material metabolism, especially glycoside energy metabolism related substances.
