Negative regulation of FAF2 and FAF4 expression in the organizing centre of the shoot meristem by CLV3. Expression of FAF2 (A, C) and FAF4 (B, D) in wild-type control plants (A, B) and clv3-7 mutants (C, D). Expression of FAF2 (C) and FAF4 (D) is elevated in clv3-7 mutants when compared to wild-type controls (A, B). (E, F) Microarray expression profiles of WUS and the FAF genes. (E) WUS, FAF2, and FAF4 are significantly upregulated and change more than 2-fold (solid lines) in clv3-7, while FAF1 and FAF3 do not (dashed lines). (F) FAF genes do not respond to ectopic WUS expression. Scale bar: 100 μm.
