Floral Developmental Morphology of Amborella trichopoda (Amborellaceae) (2004, neutral): “…of this model are (1) the addition of E-function genes as cospecifiers of petals, stamens, and carpels in Arabidopsis (Liljegren et al. 2000; Pelaz et al. 2000; Theissen 2001; Winter et al. 2002a, 2002b; Vandenbussche et al. 2003) and (2) the recognition that B-class gene expression is not…”
Evolution of Floral Structures in Basal Angiosperms (2003, background): “…(e.g., Coen and Meyerowitz 1991; Meyerowitz et al. 1991; Weigel and Meyerowitz 1994 [reviewed in Baum and Whitlock 1999]; Kramer and Irish 2000; Pelaz et al. 2000; Soltis et al. 2000b; Theissen et al. 2000, 2002) can be used to explain differentiation of the perianth into sepals and petals.”
Highly Specific Gene Silencing by Artificial MicroRNAs in Arabidopsis[W][OA] (2006, background): “Flowers of overexpressers had severe changes in floral morphology with leaf-like organs in all four whorls, characteristic of sepallata (sep) multiple mutants (Pelaz et al., 2000) (Figure 3E).”
The SEP4 gene of Arabidopsis thaliana functions in floral organ and meristem identity. (2004, background): “These data organs are converted into sepals in sep1 sep2 sep3 raise the possibility that a redundant gene might mask triple mutants [ 3 , 4]. Additional studies indicate that the roles of SEP1, SEP2 and SEP3 in sepal development the SEP proteins form multimeric complexes with the and therefore sugge”
An Evaluation of A‐Function: Evidence from the APETALA1 and APETALA2 Gene Lineages (2007, background): “…genes (SEP1–SEP4) have been shown in Arabidopsis to provide an E-function that is also required for flower formation and for proper specification of floral organ identity (Pelaz et al. 2000, 2001b; Honma and Goto 2001; Theissen and Saedler 2001; Vandenbussche et al. 2003b; Ditta et al. 2004).”
Complexes of MADS-box proteins are sufficient to convert leaves into floral organs (2001, background): “However, attempts to convert vegetative organs into floral organs by altering the expression of ABC genes have been unsuccessfu”
No Flower no Fruit - Genetic Potentials to Trigger Flowering in Fruit Trees (2007, background): “The necessity of SEP genes for proper flower organ development (Pelaz et al. 2000, 2001) and the finding that MADS-box protein form ternary complexes (Egea-Cortines et al. 1999) led to the floral quartet model (Theißen 2001; Theißen and Saedler 2001), proposing that tetrameric complexes of floral…”
Developmental Gene Evolution and the Origin of Grass Inflorescence Diversity (2006, background): “For example, Arabidopsis sep1 sep2 sep3 (sepallata) triple mutant flowers are composed entirely of sepal‐like structures, and sep1 sep2 sep3 sep4 quadruple mutants have flowers composed entirely of leaf‐like structures (Ditta et al., 2004; Pelaz et al., 2000).”
Class III Homeodomain-Leucine Zipper Gene Family Members Have Overlapping, Antagonistic, and Distinct Roles in Arabidopsis Developmentw⃞ (2005, background): “Reverse genetic analysis has been increasingly productive in studying functional redundancy in Arabidopsis gene families (Hua and Meyerowitz, 1998; Siegfried et al., 1999; Pelaz et al., 2000; Alonso et al., 2003; Franklin et al., 2003a, 2003b; Friml et al., 2003; Pinyopich et al., 2003).”
Genetic Regulation of Fruit Development and Ripening (2004, background): “…SEPALLATA genes (SEP1, SEP2, and SEP3) can be eliminated via mutation individually with minimal impact on floral development, yet the triple mutant results in the conversion of all floral organs to sepals, indicating roles in normal petal, stamen, and carpel development (Pelaz et al., 2000).”
