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 ...

Although many models have been proposed that could lead to the maintenance of gene duplicates, the ways in which interacting gene duplicates influence each other's evolution and function remain poorly understood. Here, we focus on duplication and loss of the B class MADS box transcription factor genes in the euasterids I and the ramifications of such changes on paralog evolution and their encod...

MADS-box genes form a large gene family in plants and are involved in multiple biological processes, such as flowering. However, the regulation mechanism of MADS-box genes in flowering remains unresolved, especially under short-term cold conditions. In the present study, we isolated BcMAF1, a Pak-choi (Brassica rapa ssp. Chinensis) MADS AFFECTING FLOWERING (MAF), as a floral repressor and funct...

MIKCc-type MADS-box genes encode key transcriptional regulators of a variety of developmental processes in Arabidopsis thaliana. However, there has been relatively little effort to systematically carry out comparative genomic or functional analyses of these genes across flowering plants. Here we describe a strategy to identify members of the MIKCc-type MADS-box gene family from any angiosperm s...

B-class MADS box genes specify petal and stamen identities in several core eudicot species. Members of the Solanaceae possess duplicate copies of these genes, allowing for diversification of function. To examine the changing roles of such duplicate orthologs, we assessed the functions of B-class genes in Nicotiana benthamiana and tomato (Solanum lycopersicum) using virus-induced gene silencing ...
