英文摘要	Zygomorphic flowers, with bilateral (dorsoventral) symmetry, are considered to have evolved several times independently in flowering plants. in antirrhinum majus, floral dorsoventral symmetry depends on the activity of two tcip-box genes, cycloidea (cyc) and dichotoma (dich). to examine whether the same molecular mechanism of floral asymmetry operates in the distantly related rosid clade of eudicots, in which asymmetric flowers are thought to have evolved independently, we investigated the function of a cyc homologue ljcyc2 in a papilionoid legume, lotus japonicus. we showed a role for ljcyc2 in establishing dorsal identity by altering its expression in transgenic plants and analyzing its mutant allele squared standard 1 (squ1). furthermore, we identified a lateralizing factor, keeled wings in lotus 1 (kew1), which plays a key role in the control of lateral petal identity, and found ljcyc2 interacted with kew1, resulting in a double mutant that bore all petals with ventralized identity to some extents. thus, we demonstrate that cyc homologues have been independently recruited as determinants of petal identities along the dorsoventral axis in two distant lineages of flowering plants, suggesting a common molecular origin for the mechanisms controlling floral zygomorphy.
