〈p〉The basal land plant liverwort spends most of its life cycle in a haploid state with distinct male and female morphology. A conserved MYB-type transcription factor regulates the sexual differentiation process, suggesting a shared origin for gamete formation in plants.〈/p〉
〈p〉 〈l type="unord"〉〈li〉〈p〉The autosomal MpFGMYB gene promotes female sexual differentiation in the liverwort 〈i〉Marchantia polymorpha〈/i〉.〈/p〉〈/li〉
〈li〉〈p〉MpFGMYB belongs to a MYB subfamily whose members are known to regulate female gametophyte development in 〈i〉Arabidopsis thaliana〈/i〉.〈/p〉〈/li〉
〈li〉〈p〉Expression of MpFGMYB is suppressed in males by its antisense gene SUF〈i〉in cis〈/i〉.〈/p〉〈/li〉
〈li〉〈p〉Loss-of-function mutations of either MpFGMYB in females or SUF in males leads to near-complete sex conversion phenotypes.〈/p〉〈/li〉〈/l〉 〈/p〉〈/sec〉
