RADIALIS origin and expression suggest ancestral function in female organs of seed plants

The paper traces the evolutionary origin of RADIALIS genes from DIVARICATA genes in seed plants and finds their expression in female organs like ovules in Ginkgo biloba.

On/off switches in the DIVARICATA-based regulatory network evolved through gene duplication, fusion, and truncation.

The paper traces the evolutionary origin of DIV genes and their regulatory network components through gene duplication, fusion, and truncation events, revealing their role in developmental regulation.
