Differential 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 کاملAnalysis of the Petunia TM6 MADS box gene reveals functional divergence within the DEF/AP3 lineage.
Antirrhinum majus DEFICIENS (DEF) and Arabidopsis thaliana APETALA3 (AP3) MADS box proteins are required to specify petal and stamen identity. Sampling of DEF/AP3 homologs revealed two types of DEF/AP3 proteins, euAP3 and TOMATO MADS BOX GENE6 (TM6), within core eudicots, and we show functional divergence in Petunia hybrida euAP3 and TM6 proteins. Petunia DEF (also known as GREEN PETALS [GP]) i...
متن کاملThe cDNA sequence of two MADS box proteins in Petunia.
Severa1 homeotic genes that are involved in floral differentiation have recently been isolated and characterized from Antirrhinum majus and Arabidopsis thaliana (Sommer et al., 1990; Yanofsky et al., 1990). Based on genetic and molecular studies, a model has been proposed to explain the roles of different homeotic genes in the specification of floral organ identity (Bowman et al., 1991). To see...
متن کاملA Nove1 Class of MADS Box Genes 1s lnvolved in Ovule Development in Petunia
We isolated and characterized two ovule-specific MADS box cDNAs from petunia, designated floral binding protein (fbp) genes 7 and 11. The putative protein products of these genes have -90% of their overall amino acid sequence in common. In situ RNA hybridization experiments revealed that both genes are expressed in the center of the developing gynoecium before ovule primordia are visible. At la...
متن کاملA novel class of MADS box genes is involved in ovule development in petunia.
We isolated and characterized two ovule-specific MADS box cDNAs from petunia, designated floral binding protein (fbp) genes 7 and 11. The putative protein products of these genes have approximately 90% of their overall amino acid sequence in common. In situ RNA hybridization experiments revealed that both genes are expressed in the center of the developing gynoecium before ovule primordia are v...
