Alteration of lipid biosynthesis in WD embryos between 24 and 33 DAP. Red and blue circles were used to account for significantly increased or decreased levels of each FA at each stage, respectively (n = 4, P < 0.05). Red and blue boxes were used to show the significantly up‐ or down‐regulated expression of each enzyme at each stage under greenhouse conditions, respectively (n = 3, P < 0.05, |log2(Fold Change)| ≥ 1). The symbol # next to the corresponding enzyme number denotes the presence of the AW‐box motif in the promoter of the enzyme’s gene.
