Eucalypt MADS-box genes expressed in developing flowers.
Three MADS-box genes were identified from a cDNA library derived from young flowers of Eucalyptus grandis W. Hill ex Maiden. The three egm genes are single-copy genes and are expressed almost exclusively in flowers. The egm1 and egm3 genes shared strongest homology with other plant MADS-box genes, which mediate between the floral meristem and the organ-identity genes. The egm3 gene was also exp...
متن کاملCharacterization of MADS-box genes in charophycean green algae and its implication for the evolution of MADS-box genes.
The MADS-box genes of land plants are extensively diverged to form a superfamily and are important in various aspects of development including the specification of floral organs as homeotic selector genes. The closest relatives of land plants are the freshwater green algae charophyceans. To study the origin and evolution of land plant MADS-box genes, we characterized these genes in three charop...
متن کامل-Box Genes Controlling Inflorescence Morphogenesis in Sunflower
MADS -box genes play an important role in plant ontogeny, particularly, in the regulation of floral organ induction and development. Eight full-length cDNAs of HAM genes ( Helianthus annuus MADS ) have been isolated from sunflower. They encode MADS-box transcription factors expressed in inflorescence tissues. In the frames of the ABCDE model, the HAM proteins were classified according to their ...
متن کاملIdentification and characterization of three orchid MADS-box genes of the AP1/AGL9 subfamily during floral transition.
Gene expressions associated with in vitro floral transition in an orchid hybrid (Dendrobium grex Madame Thong-In) were investigated by differential display. One clone, orchid transitional growth related gene 7 (otg7), encoding a new MADS-box gene, was identified to be specifically expressed in the transitional shoot apical meristem (TSAM). Using this clone as a probe, three orchid MADS-box gene...
متن کاملIdentification of genes dependent on the MADS box transcription factor SrfA in Dictyostelium discoideum development.
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.
