The REV MEKHLA Domain Behaves Distinctly from the Other HD-ZIP III MEKHLA Domains.

(A) Results of Y2H experiments. Strong, medium, mild, and no interactions are indicated by three plus signs, two plus signs, one plus sign, and a minus sign, respectively. Interaction strengths were determined by comparison to a set of standards (see Supplemental Figure 5 online). Reciprocal bait/prey couples are indicated by a number in parenthesis. B-a, bait autoactivation.

(B) Results of Y2H experiments. No interaction is indicated by a minus sign.

(C) A representative individual of 35S-PHB* transgenic plants (4 weeks old). miRNA-resistant PHB is designated PHB*. Bar = 100 mm.

(D) A representative individual of 35S-PHB*-ΔMEKHLA transgenic plants (4 weeks old). miRNA-resistant PHB is designated PHB*. Bar = 100 mm.
