NnMYB48 in lotus (Nelumbo nucifera) is linked to higher aporphine alkaloid production, with transient overexpression increasing major alkaloid accumulation.
- Why it matters: Aporphine alkaloid biosynthesis in lotus depends on transcriptional regulation, but the specific roles of MYB transcription factors in this pathway were not well defined.
- What they did: Using the lotus telomere-to-telomere genome, the study cataloged MYB genes and screened 44 expression-linked candidates; NnMYB48 was tested via transient overexpression, dual-luciferase, yeast one-hybrid, and EMSA.
- The result: NnMYB48 shows rapid MeJA-responsive expression in leaves and directly binds NnTYDC and NnCYP80G promoters, activating transcription and promoting aporphine biosynthesis.
