BIA Biosynthesis Gene Expression and Localization During Development. (A) Heatmap of BIA biosynthesis-related gene expression during P. somniferum development. The heatmap shows gene expression patterns across roots R, stems S, leaves L, ovaries C, and fruits F during vegetative stage VP, flowering stage FLP, fruit development stage FRDP, and fruit maturation stage FRMP. NA indicates genes with no annotation. (B) Localization of BIA-related genes during development. Red indicates genes significantly enriched in the BIA biosynthesis pathway, black represents genes enriched in other pathways, and blank indicates genes with no enrichment.
