Figure 2. — SEP3 tetramers are required for the normal development of the fourth whorl and flower determinacy in Arabidopsis. (A–D) show inflorescences in WT, sep1/2/3 and the sep1/2/3 triple mutant transformed with either SEP3 (C) or SEP3^Δtet (D) construct. Flower indeterminacy (arrows) is observed in B and D, while normal siliques (arrows) are produced in A and C. (E–H) show close-ups of a young flower as per A to D. Sep1/2/3 flowers usually stay closed as in (F). (I–L) Close-ups after dissection of E to H. The fourth whorl of sep1/2/3 SEP3^Δtet plants shows organ defects (L) and indeterminacy (M–P). Scale bar is 1 cm in A to D, 1 mm in E to O, and 0.5 mm in P.
