Comment
A fruit replum develops from the ovary replum and has no suture line in its center, while a fruit septum (PO:0025262) develops from an ovary septum via the fusion of two adjacent ovary walls. Common in Brassicaceae. Annotations for Arabidopsis fruit should go here, and not under fruit septum.
