The specification of floral organ identity in the higher dicots depends on the function of a
limited set of homeotic genes, many of them members of the MADS-box gene family. Two …

Our recently acquired understanding of the ABC program, which controls floral organ identity
in model plant species such as Arabidopsis thaliana and Antirrhinum majus, has provided a …

Changes in homeotic gene expression patterns or in the functions of the encoded proteins
are thought to play a prominent role in the evolution of new morphologies. The floral …

The B class genes, including homologs of the Arabidopsis loci APETALA3 (AP3) and
PISTILLATA (PI), appear to play a conserved role in the determination of petal and stamen …

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 …

The ABC model of flower organ identity is widely recognized as providing a framework for
understanding the specification of flower organs in diverse plant species [1]. Recent studies …

Phylogenetic analyses of angiosperm MADS-box genes suggest that this gene family has
undergone multiple duplication events followed by sequence divergence. To determine …

The specification of floral organ identity during development depends on the function of a
limited number of homeotic genes grouped into three classes: A, B, and C. Pairs of …

The ABC model of floral organ identity is based on studies of Arabidopsis and Antirrhinum,
both of which are highly derived eudicots. Most of the genes required for the ABC functions …

Members of the SEPALLATA (SEP) MADS-box subfamily are required for specifying the
“floral state” by contributing to floral organ and meristem identity. SEP genes have not been …
