SEPALLATA (SEP) proteins are MADS-domain transcription factors that regulate a plethora of processes during flower development. A total of four SEP genes, termed SEP1 (AT5G15800) , SEP2 (AT3G02310) , SEP3 (AT1G24260) and SEP4 (AT2G03710) , also known as AGL2, AGL4, AGL9 and AGL3, respectively were found in AraBidopsis thaliana genome.
