Abstract As a typical monoecious plant, maize (Zea mays L.) produces unisexual male and female flowers comprising tassels ears, respectively. However, the molecular mechanisms underlying flower development remain largely unclear. Here, we identify pair of homeodomain-leucine zipper (HD-ZIP) transcription factors, Grassy tiller1 (GT1) ZmHB13 (also termed VRS1-like1, VRL1), which act synergistically to control carpel in maize. Mutations GT1, but not ZmHB13/VRL1, cause defects abortion tassels,...
