This entry includes a group of zinc finger proteins, including JAGGED protein (At1g68480) from Arabidopsis and STAMENLESS 1 from Oryza sativa subsp. japonica. JAGGED is a transcription factor that is activated in the emerging organ primordia and in the distal region of immature organs. It controls growth anisotropy and coordination between cell size and cell cycle during plant organogenesis. STAMENLESS 1 is involved in floral development and has been shown to regulate the expression of the SPW1/OsMADs16 protein.
