Exploring carpel evolution: morphological, anatomical, and STM gene expression evidence from Illicium carpel
The origin of the carpel is crucial for understanding the evolution of angiosperms. A key unresolved debate centres on whether ovules originate from leaf-like structures or shoot structures. We conducted morphological, anatomical, and gene expression investigations on floral buds of Illicium henryi (Schisandraceae) a...
