RAGGED SEEDLING2 is required for expression of KANADI2 and REVOLUTA homologues in the maize shoot apex.

The anatomy of ragged seedling2-R (rgd2-R) leaves is disorganized along the adaxial/abaxial axis. Mutant leaves often exhibit radial morphology but unlike similar mutants, rgd2-R radial leaves have no reduction of adaxial or abaxial identity. Previously, we proposed that RGD2 does not establish adaxial or abaxial fate but performs a signaling function… CONTINUE READING
