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...

The MADS-box transcription factors play essential roles in various processes of plant growth and development. In the present study, phylogenetic analysis of 142 apple MADS-box proteins with that of other dicotyledonous species identified six putative Dormancy-Associated MADS-box (DAM) and four putative Flowering Locus C-like (FLC-like) proteins. In order to study the expression of apple MADS-bo...

MADS-box genes are a large family of transcription factors initially discovered for their role during development of flowers and fruits. The MADS-box transcription factors from animals have been studied by X-ray protein crystallography but those from plants remain to be studied. In this work, a MADS-box cDNA from mango encoding a protein of 254 residues was obtained and compared. Based on phylo...

We have generated 47 DNA pools and 235 subpools from 21,049 T-DNA insertion lines of rice. DNA pools of 500-1,000 lines were adequate for screening a T-DNA insertion within a 2-kb region. To examine the efficacy of the DNA pools, we selected MADS-box genes, which play an important role in controlling various aspects of plant development. A total of 34 MIKC-type MADS-box genes have now been iden...

MADS-box genes encode transcriptional regulators that are critical for flowering, flower organogenesis and plant development. Although there are extensive reports on genes involved in flower organogenesis in model and economically important plant species, there are few reports on MADS-box genes in woody plants. In this study, we have cloned and characterized AGAMOUS (AG), SEEDSTICK (STK) and SE...

MADS-box genes have been shown to play a role in the formation of fruits, both in Arabidopsis and in tomato. In peach, two C-class MADS-box genes have been isolated. Both of them are expressed during flower and mesocarp development. Here a detailed analysis of a gene that belongs to the PLENA subfamily of MADS-box genes is shown. The expression of this PLENA-like gene (PpPLENA) increases during...

MADS genes encode a family of transcription factors, some of which control the identities of floral organs in flowering plants. Most of the MADS-box genes in fern have been cloned and analyzed in model plants, such as Ceratopteris richardii and Ceratopteris pteridoides. In this study, a new MADS-box gene, DfMADS1(GU385475), was cloned from Dryopteris fragrans (L.) Schott to better understand th...

Floral homeotic genes that control the specification of meristem and organ identity in developing flowers have been isolated from both Arabidopsis thaliana and Antirrhinum majus. Most of these genes belong to a large family of regulatory genes and possess a characteristic DNA binding domain known as the MADS-box. Members of this gene family display primarily floral-specific expression and are h...

Since the time of Darwin, biologists have studied the origin and evolution of the Orchidaceae, one of the largest families of flowering plants. In the last two decades, the extreme diversity and specialization of floral morphology and the uncoupled rate of morphological and molecular evolution that have been observed in some orchid species have spurred interest in the study of the genes involve...
