SAW and BEL1 Proteins Exhibit Sequence Similarity and Functional Redundancy.

(A) Phylogram of the 13 members of the BLH protein family. Bootstrap values are shown at the branch points.

(B) Yeast two-hybrid X-Gal filter assay showing interactions of BLH and KNOX proteins. The BLH proteins were used as baits and KNOX proteins as preys. Cruc, Cruciferin (negative control).

(C) Whole mounts of mature ovules showing complementation of the bel1 mutant by 35S:SAW1. (a) The wild type (b) bel1-3, (c) 35S:SAW1, and (d) 35S:SAW1 bel1-3. Bars = 50 μm.
