Overview of genes involved in the biosynthesis pathway of fatty acid and amino acid. A Simplified pathway of fatty acid biosynthesis, elongation and transport. B Alignment of the partial peptide sequences of homoACCases from Triticum aestivum, Brassica napus, and Sapria himalayana. Identical amino acids are underlayed with same color intensities. Genebank accession numbers of ACC1, ACC2_1, ACC2_2 of T. aestivum were T06161, Q41511, Q41525, and ACC1 accession number of B. napus was X77576. C Heatmap showing the z-score transformed gene expression data on fatty acid biosynthesis. D, E The biosynthesis pathway of aromatic amino acids and lysine in plant plastid, respectively. The key enzymes in each pathway are shown to the right of the arrows, which are all nuclear-encoded plastid-localized proteins. F Heatmap showing the log2-transformed gene expression data on amino acid biosynthesis. 2th, 4th, 6th, and 8th_layers indicate transverse layers of flower buds of S. himalayana. The full name of each gene was listed in Table S17
