Over the past decade, the ABC model of flower development has been widely promulgated. However, correct flower-organ development requires not only the ABC genes but also the SEPALLATA genes. When the SEPALLATA genes are expressed together with the ABC genes, both vegetative and cauline leaves are converted to floral organs. Most of the ABC genes and all three SEPALLATA genes encode MADS transcr...

BACKGROUND The myocyte enhancer factor 2 (MEF2) gene family is broadly expressed during the development and maintenance of muscle cells. Although a great deal has been elucidated concerning MEF2 transcription factors' regulation of specific gene expression in diverse programs and adaptive responses, little is known about the origin and evolution of the four members of the MEF2 gene family in ve...

Classic MIKC-type MADS-box genes (MIKC(c)) play diverse and crucial roles in angiosperm development, the most studied and best understood of which is the specification of floral organ identities. To shed light on how the flower evolved, phylogenetic and functional analyses of genes involved in its ontogeny, such as the MIKC(c) genes, must be undertaken in as broad a selection as possible of pla...

The design of key nonlinear systems often requires the use expensive blackbox simulations presenting inherent discontinuities whose positions in variable space cannot be analytically predicted. Without further precautions, solution related optimization problems leads to configurations which may close output functions. These betray unsafe regions space, such as resonance regions. To account for ...

Several genome-wide studies demonstrated that alternative splicing (AS) significantly increases the transcriptome complexity in plants. However, the impact of AS on the functional diversity of proteins is difficult to assess using genome-wide approaches. The availability of detailed sequence annotations for specific genes and gene families allows for a more detailed assessment of the potential ...

In both Antirrhinum (Antirrhinum majus) and Arabidopsis (Arabidopsis thaliana), the floral B-function, which specifies petal and stamen development, is embedded in a heterodimer consisting of one DEFICIENS (DEF)/APETALA3 (AP3)-like and one GLOBOSA (GLO)/PISTILLATA (PI)-like MADS box protein. Here, we demonstrate that gene duplications in both the DEF/AP3 and GLO/PI lineages in Petunia hybrida (...

The majority of strains of Candida albicans can switch frequently and reversibly between two or more general phenotypes, a process now considered a putative virulence factor in this species. Candida albicans WO-1 switches frequently and reversibly between a white and an opaque phase, and this phenotypic transition is accompanied by the differential expression of white-phase-specific and opaque-...

RATIONALE Mandibular advancement devices (MADs) are used to treat obstructive sleep apnoea-hypopnoea syndrome (OSAHS) but evidence is lacking regarding their clinical and cost-effectiveness in less severe disease. OBJECTIVES To compare clinical- and cost-effectiveness of a range of MADs against no treatment in mild to moderate OSAHS. MEASUREMENTS AND METHODS This open-label, randomised, con...

Nowadays, classical conceptual models (such as ER or UML) are used for designing database applications. These classical conceptual models usually come with associated CASE tools assisting the user from the creation of the conceptual schema until the generation of a physical schema for a relational or an object-relational DBMS. However, when developing spatial or temporal databases such classica...
