Genetic Separation of Third and Fourth Whorl Functions of AGAMOUS

AGAMOUS (AG) is an Arabidopsis MADS box gene required for normal
development of the third and fourth whorls of the flower. In previously
described ag mutants, the third whorl stamens are replaced by petals, and
the fourth whorl is replaced by another (mutant) flower. We describe two
new ag alleles, ag-4 and AG-Met205, retaining partial AG activity. Both
produce flowers with stamens in the third whorl and indeterminate floral
meristems; however, ag-4 flowers contain sepals in the fourth whorl, and
AG-Met205 produces carpels. The ag-4 mutation results in partial loss of
the C terminus of the K domain, a putative coiled coil, and AG-Met205
contains a site-directed mutation that causes a single amino acid change in
this same region of the K box. Two models that might explain how these
changes in AG result in the separation of different AG activities are
discussed.
