Proposed gene networks involved in hydroxy fatty acids and triacylglycerol biosynthesis in H. benghalensis seeds. The expression levels (represented by Log2FPKM) of the possible candidates are highlighted in color scales (blue to red scale) in H. benghalensis developing seeds at different development stages (S1–S5).
