A single-nucleus RNA sequencing reveals the differential fate mechanism underlying flavonoid biosynthesis of middle and inner tepals in Chimonanthus praecox

Key Points

• Flavonoid biosynthesis was shown to differ between middle and inner tepals in Chimonanthus praecox, highlighting a unique mechanism.
• Single-nucleus RNA sequencing identified distinct gene expression patterns linked to flavonoid production in tepals.
• Analyses focused on the structures of tepals, offering insights into their biosynthetic pathways and developmental roles.
• This study underscores the importance of understanding the regulatory mechanisms behind plant secondary metabolites for breeding.
