A new family of DNA binding proteins includes putative transcriptional regulators of theAntirrhinum majus floral meristem identity geneSQUAMOSA

Several sites of nuclear protein interaction within the promoter region of theAntirrhinum majus floral meristem identity geneSQUAMOSA were detected using an electrophoretic mobility shift assay. One of these sites displayed a particularly clear interaction with nuclear protein extracted from inflorescences but not with nuclear protein extracted from young, non-flowering plants. This site could thus represent a binding motif for a transcriptional...
