Differential Expression and Fold Change of BIA-Related Genes During Development. (A-D) Volcano plots showing differentially expressed genes between the fruit development stage FRDP and fruit maturation stage FRMP in P. somniferum across different tissues: A Roots, B Stems, C Leaves, and D Fruits. Upregulated genes are labeled as Up, and downregulated genes as Down. (E) Position of TYDC and PPO genes in the initial steps of the BIA biosynthesis pathway. (F) Fold change in BIA-related gene expression in roots R, stems S, and fruits F during FRDP and FRMP. Numbers -1, -2, -3, etc., indicate different gene copies.
