Regulated gene expression makes an important contribution to cell cycle control mechanisms. In fission yeast, a group of genes is coordinately expressed during a late stage of the cell cycle (M phase and cytokinesis) that is controlled by common cis-acting promoter motifs named pombe cell cycle boxes (PCBs), which are bound by a trans-acting transcription factor complex, PCB binding factor (PBF...
Aristolochia fimbriata (Aristolochiaceae: Piperales) exhibits highly synorganized flowers with a single convoluted structure forming a petaloid perianth that surrounds the gynostemium, putatively formed by the congenital fusion between stamens and the upper portion of the carpels. Here we present the flower development and morphology of A. fimbriata, together with the expression of the key regu...
The ABC model, which was accepted for almost a decade as a paradigm for flower development in angiosperms, has been subjected recently to a significant modification with the introduction of the new class of E-function genes. This function is required for the proper action of the B- and C-class homeotic proteins and is provided in Arabidopsis by the SEPALLATA1/2/3 MADS box transcription factors....
Plants enter their reproductive phase when the environmental conditions are favourable for the successful production of progeny. The transition from vegetative to reproductive phase is influenced by several environmental factors including ambient temperature. In the model plant Arabidopsis thaliana, SHORT VEGETATIVE PHASE (SVP) is critical for this pathway; svp mutants cannot modify their flowe...
Analysis of microarrays containing 6,345 Dictyostelium discoideum genes has identified 21 whose expression is dependent on the MADS box transcription factor SrfA. In wild-type cells, all of these genes are induced late in development. At least four of them are necessary for proper spore differentiation, stability, and/or germination.
In Arabidopsis thaliana, the three MADS box genes SEEDSTICK (STK), SHATTERPROOF1 (SHP1), and SHP2 redundantly regulate ovule development. Protein interaction studies have shown that a multimeric complex composed of the ovule identity proteins together with the SEPALLATA MADS domain proteins is necessary to determine ovule identity. Despite the extensive knowledge that has become available about...
