Genetic Interaction of PID and GNOM.

(A) to (D) Patterning defects in mutant embryos compared with wild-type embryos (A). Apical and basal patterning defects in gnom^R5 mutant embryos (B). More severe apical-to-basal embryonic patterning defects in 35S_Pro:PID gnom^R5 double mutants (C), sometimes leading to the complete loss of apical basal patterning (D).

(E) and (F) Viable 35S_Pro:PID (E) and gnom^R5 (F) seedlings.

(G) Strongly affected seedling morphology and growth arrest in 35S_Pro:PID gnom^R5 double mutants, resembling full gnom knockout mutants.
