Figure 9. Role of SEP3 in Auxin Signaling.

Figure 9

(A) Wild-type Arabidopsis flower.

(B) ett mutant flower, two sepals and petals removed.

(C and D) Flowers of SEP3-EAR plants (pSEP3::SEP3-EAR in sep3–1 mutant) with strong mutant phenotype, sepals (and filamentous organs in [D]) were removed to reveal the inner organs.

(E) Inflorescence of SEP3-EAR plant.

(F) Inflorescence of ett-1 mutant.

(G) SEM picture of a flower from a SEP3-EAR plant revealing abnormal ovule placentation and enlarged stigmatic tissue (sepals were removed).

(H and I) Localization of nuclear localized DR5::YFP (yellow) in a floral meristem (H). Localization of SEP3-GFP driven from its own promoter in a floral meristem (I). Arrows indicate similar localization of the DR5 marker and SEP3 in sepal tips. White bar indicates 30 μm.

(J) Flower of a sep1 sep2/SEP2 sep3 mutant plant with stalked carpel.

(K) pid mutant flower with stalked carpel.

(L–N) Venation patterns in wild-type (L) and SEP3-EAR carpels (M) and (N).
