Ovule development in Arabidopsis involves the formation of three morphologically defined proximal-distal pattern elements. Integuments arise from the central pattern element. Analysis of Bell 1 (Bel 1) mutant ovules indicated that BEL1 was required for integument development. Cloning of the BEL1 locus reveals that it encodes a homeodomain transcription factor. Prior to integument initiation, BE...
We have cloned cDNA encoding a human transcription factor that belongs to the MEF2 (myocyte-specific enhancer-binding factor 2) subfamily of the MADS (MCM1-agamous-deficiens-serum response factor) gene family. This factor, which we have named MEF2C, binds specifically to the MEF2 element and activates transcription via this element. Specific isoforms of this factor are found exclusively in brai...
The MADS box gene, AGAMOUS-LIKE 20 (AGL20), integrates environmental and endogenous flowering signals in Arabidopsis thaliana. In order to determine if its role is conserved in other plants, we isolated AGL20 orthologs from Brassica campestris, Cardamine flexuosa and Draba nemorosa. The putative amino acid sequences of the orthologs were 94 to 97% identical. We analyzed the flowering phenotype ...
The homeotic gene AGAMOUS (AG) has dual roles in specifying organ fate and limiting stem cell proliferation in Arabidopsis flowers. We show that the floral identity protein LEAFY (LFY), a transcription factor expressed throughout the flower, cooperates with the homeodomain protein WUSCHEL (WUS) to activate AG in the center of flowers. WUS was previously identified because of its role in maintai...
