ABSTRACT 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 transcription
factors, which bind to DNA as dimers. Here, amendments to the ABC model are considered that incorporate
both the SEPALLATA genes and the ability of MADS proteins to form higher-order complexes.

ABSTRACT The production of a flower requires several events to occur. A floral meristem must form, boundaries
must be set to enable discrete primordia to arise and the primordia must adopt the correct organ identity.
Homeotic mutants, whose organs adopt inappropriate identities for their position within the flower, have helped
the construction of a simple combinatorial model to explain how floral organ identity is defined. However,
recent experiments suggest that the regulation of floral organ identity is more complex than was previously
apparent. The simple interactions are becoming more complex and the universal applicability of the model
less clear.

ABSTRACT To understand the genetic architecture of floral development, including the origin and
subsequent diversification of the flower, data are needed not only for a few model organisms but
also for gymnosperms, basal angiosperm lineages and early-diverging eudicots. We must link what
is known about derived model plants such as Arabidopsis, snapdragon and maize with other
angiosperms. To this end, we suggest a massive evolutionary genomics effort focused on the
identification and expression patterns of floral genes and elucidation of their expression patterns
in 'missing-link' taxa differing in the arrangement, number and organization of floral parts. The
Floral Genome Project: a sequence, expression and informatics-based investigation of flower evolution.

TITLE New members of the floral organ identity AGAMOUS pathway

ABSTRACT The Arabidopsis floral organ identity gene AGAMOUS (AG) specifies stamen and
carpel development as well as floral determinacy. Recent reports suggest that the HUA1,
HUA2, HEN1 and HEN2 genes function redundantly as components of the AG pathway. The HUA1,
HUA2, HEN1 and HEN2 genes encode nuclear proteins that perhaps play a role in RNA metabolism.
The HUA and HEN genes function not only on the AG pathway, but also in vegetative development.
The HUA and HEN genes function redundantly in the C-class AGAMOUS pathway to specify stamen
and carpel development as well as floral meristem determinacy.
