Through multifaceted genome-scale research involving phylogenomics, targeted gene surveys, and gene expression analyses in diverse basal lineages of angiosperms, our studies provide insights into the most recent common ancestor of all extant flowering plants. MADS-box gene duplications have played an important role in the origin and diversification of angiosperms. Furthermore, early angiosperms...
Three cDNAs showing a high degree of homology to the SQUA subfamily of MADS box genes were isolated and characterized from the lily (Lilium longiflorum). Lily MADS Box Gene 5 (LMADS5) showed high sequence identity to oil palm (Elaeis guineensis) SQUAMOSA3 (EgSQUA3). LMADS6 is closely related to LMADS5 whereas LMADS7 is more related to DOMADS2, an orchid (Dendrobium) gene in the SQUA subfamily. ...
We report the discovery of an Antirrhinum MADS-box gene, FARINELLI (FAR), and the isolation of far mutants by a reverse genetic screen. Despite striking similarities between FAR and the class C MADS-box gene PLENA (PLE), the phenotypes of their respective mutants are dramatically different. Unlike ple mutants, which show homeotic conversion of reproductive organs to perianth organs and a loss o...
Floral morphological novelties, like homeotic changes of whorl 1 organs, can easily arise by modifying existing regulatory networks. Ectopic expression of B-function MADS-box genes in whorl 1 leads to a replacement of sepals by petals, as is found in the Liliaceae. In cases where leaf-like sepals or even inflated calyces develop, which ultimately envelop the mature fruit as in Physalis, ectopic...
Gene duplication is a substrate of evolution. However, the relative importance of positive selection versus relaxation of constraints in the functional divergence of gene copies is still under debate. Plant MADS-box genes encode transcriptional regulators key in various aspects of development and have undergone extensive duplications to form a large family. We recovered 104 MADS sequences from ...
MADS-box transcription factors are highly conserved in eukaryotic species and involved in a variety of biological processes. Little is known, however, regarding the function of MADS-box genes in Botrytis cinerea, a fungal pathogen with a wide host range. Here, the functional role of the B. cinerea MADS-box gene, Bcmads1, was characterized in relation to the development, pathogenicity and produc...
