Following
statements are regarding to the the floral quartet model and the underlying
ABCDE model of organ identity determination in Arabidopsis thaliana.
A.
Five floral organ identities (sepals, petals, stamens, carpels, and ovules) are
specified by the formation of floral organ-specific tetrameric complexes of
MADS-domain transcription factors that bind to two nearby enhancer elements,
forming a DNA loop in between.
B.
A complex of two class A proteins (APETALA 1) and two class E proteins (SEPALLATA) determines petal identity.
C.
A complex of one class A protein, one class E protein, and one of each of the
class B proteins (APETALA 3 and PISTILLATA) determines sepal identity.
D. A complex of one class E protein, two class B proteins, and one class C protein (AGAMOUS) determines stamen identity, while a complex of two class E proteins and two class C proteins determines carpel identity.D. A complex of one class E protein, two class B proteins, and one class C protein (AGAMOUS) determines stamen identity, while a complex of two class E proteins and two class C proteins determines carpel identity.
E.
A complex of one class E protein, one class C protein, and one of each of the
class D proteins (SHATTERPROOF and SEEDSTICK) controls ovule identity.
