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 کاملDifferential expression of two MADS box genes in wild-type and mutant petunia flowers.
We isolated and characterized two flower-specific genes from petunia. The protein products of these genes, designated floral binding protein 1 (FBP1) and 2 (FBP2), are putative transcription factors with the MADS box DNA binding domain. RNA gel blot analysis showed that the fbp1 gene is exclusively expressed in petals and stamen of petunia flowers. In contrast, the FBP1 protein was only detecta...
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 کاملMADS-box genes are involved in floral development and evolution.
MADS-box genes encode transcription factors in all eukaryotic organisms thus far studied. Plant MADS-box proteins contain a DNA-binding (M), an intervening (I), a Keratin-like (K) and a C-terminal C-domain, thus plant MADS-box proteins are of the MIKC type. In higher plants most of the well-characterized genes are involved in floral development. They control the transition from vegetative to ge...
متن کاملDiverse roles for MADS box genes in Arabidopsis development.
Members of the MADS box gene family play important roles in flower development from the early step of determining the identity of floral meristems to specifying the identity of floral organ primordia later in flower development. We describe here the isolation and characterization of six additional members of this family, increasing the number of reported Arabidopsis MADS box genes to 17. All 11...
