Rice contains several MADS box genes. It has been demonstrated previously that one of these genes, OsMADS1 (for Oryza sativa MADS box gene1), is expressed preferentially in flowers and causes early flowering when ectopically expressed in tobacco plants. In this study, we demonstrated that ectopic expression of OsMADS1 in rice also results in early flowering. To further investigate the role of O...

MADS-box genes are crucial regulators of floral development, yet how their functions have evolved to control different aspects of floral patterning is unclear. To understand the extent to which MADS-box gene functions are conserved or have diversified in different angiosperm lineages, we have exploited the capability for functional analyses in a new model system, Papaver somniferum (opium poppy...

In 2009 and in 2011, the Library of Congress made two of its largestauthority files –Subject Headings and Names available as linked data via LC’slinked data service, id.loc.gov. Both are offered in MADS/RDF and SKOS. It isLC’s objective, in 2012, to publish another of its largest authority files as linkeddata: LC Classification. However, whereas the source records for Subject He...

MADS-domain proteins serve as regulators of plant development and often form dimers and higher order complexes to function. Heterotopic expression of MPF2, a MADS-box gene, in reproductive tissues is a key component in the evolution of the inflated calyx syndrome in Physalis, but RNAi studies demonstrate that MPF2 has also acquired a role in male fertility in Physalis floridana. Using the yeast...

The molecular mechanisms by which floral homeotic genes act as major developmental switches to specify the identity of floral organs are still largely unknown. Floral homeotic genes encode transcription factors of the MADS-box family, which are supposed to assemble in a combinatorial fashion into organ-specific multimeric protein complexes. Major mediators of protein interactions are MADS-domai...

The identification of a number of cis-elements which direct gene expression in maize endosperm, and the characterization of corresponding DNA binding proteins, point to the interaction of different classes of transcription factors in this tissue. To assess whether MADS box genes are also involved in maize endosperm development, cDNA and genomic MADS box clones have been isolated. The three cDNA...

Plants enter their reproductive phase when the environmental conditions are favourable for the successful production of progeny. The transition from vegetative to reproductive phase is influenced by several environmental factors including ambient temperature. In the model plant Arabidopsis thaliana, SHORT VEGETATIVE PHASE (SVP) is critical for this pathway; svp mutants cannot modify their flowe...

STATEMENT OF PROBLEM The use of mandibular advancement devices (MADs) in the treatment of sleep bruxism is gaining widespread importance. However, the effects of MADs on sleep bruxism scores, sleep quality, and occlusal force are not clear. PURPOSE The purpose of this clinical study was to analyze the effect of MADs on sleep bruxism scores, sleep quality, and occlusal force. MATERIAL AND ME...

BACKGROUND MADS-box genes are categorized into A, B, C, D and E classes and are involved in floral organ identity and flowering. Sheepgrass (Leymus chinensis (Trin.) Tzvel) is an important perennial forage grass and adapts well to many adverse environments. However, there are few studies on the molecular mechanisms of flower development in sheepgrass, especially studies on MADS-domain proteins....

Mini chromosome maintenance 1, agamous, deficiens, and serum response factor (MADS)-box genes are transcription factors which play fundamental roles in flower development and regulation of floral organ identity. However, till date, identification and functions of MADS-box genes remain largely unclear in Phyllostachys edulis. In view of this, we performed a whole-genome survey and identified 34 ...
