1 INTRODUCTION SUPERMAN (SUP) is a member of the C2H2 zinc-finger family of transcription factors in Arabidopsis and has been classically considered a floral-specific gene (Sakai et al., 1995; Englbrecht et al., 2004; Xu et al., 2018). The specific expression of SUP in the boundaries between primordia of reproductive organs (Sakai et al., 1995) is consistent with increased stamens and carpels in sup mutant flowers (Breuil-Broyer et al., 2016).
