Fig. 3From: Intergrative metabolomic and transcriptomic analyses reveal the potential regulatory mechanism of unique dihydroxy fatty acid biosynthesis in the seeds of an industrial oilseed crop Orychophragmus violaceusDynamics of metabolite and gene expression during four different seed developing stages. K-means algorithm grouped the 1103 metabolites (a) and 22,479 co-expressed genes (b) into three main clusters. Z-score data were standardized to -4 to 4. Statistics of the class of all metabolites (c) and free fatty acids (d) in 3 clusters. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis of co-expressed genes in cluster 3 (e), cluster 2 (f) and cluster 1 (g) are shown separatelyBack to article page
