Fig 2. KNOX2 mutant phenotypes and KNAT5 expression patterns.

Fig 2

(A-C) 10-day-old seedlings of wild-type (WT, A), knat3 knat5 (designated as knat35, B), and knat345 (C). (D-E) Wild-type (D) and knat345 (E) plants after bolting; 5 weeks-old plants are shown. (F-G) Representative wild-type (F) and knat345 (G) rosette leaves. (H-L) First cauline (stem) leaves of wild-type (H), knat3 knat4 (designated as knat34, I), knat3 knat4 knat5/+ (designated as knat34, 5/+, J), knat3 knat5 (K), and knat345 (L) plants; progressive loss of the KNOX2 activity results in increasingly serrated leaves. (M-N) Wild-type (M) and knat345 (N) flowers. (O-R) Mature wild-type (O, Q) and knat345 (P, R) ovules and embryo sacs. An arrow marks ectopic formation of tracheary elements. (S-V) pro KNAT5:KNAT5-GUS expression in developing embryos (S-T), vegetative shoot apex (U), leaf (V), and ovules (W). pro KNAT5:KNAT5-GUS is not detected in the shoot apical meristem (marked by an arrowhead) and the youngest leaf primordium (marked with an arrow). An asterisk indicates a stipule. (X) pro KNAT4:GUS expression in vegetative shoot apex. For additional expression data, see S10 Fig. Plants are all in the Columbia (Col) background. Scale bars, 1 cm.
