Why do paralogs persist? Molecular evolution of CYCLOIDEA and related floral symmetry genes in Antirrhineae (Veronicaceae).

Molecular biology and evolution - 1 Apr 2003

Hileman Lena C, Baum David A

Abstract excerpt

CYCLOIDEA (CYC) and DICHOTOMA (DICH) are paralogous genes that determine adaxial (dorsal) flower identity in the bilaterally symmetric flowers of Antirrhinum majus (snapdragon). We show here that the duplication leading to the existence of both CYC and DICH in Antirrhinum occurred before the radiation of the Antirrhineae (the tribe to which snapdragon belongs). We find no additional gene duplications within...
