Arabidopsis sol2 mutants showed CLV3 peptide resistance. Twenty-six synthetic CLE peptides were examined in the clv1, clv2 and sol2 mutants. sol2 showed different levels of resistance to the various peptides, and the spectrum of peptide resistance was quite similar to that of clv2. SOL2 encoded a receptor-like kinase protein which is identical to CORYNE (CRN). GeneChip analysis revealed that the expression of several genes was altered in the sol2 root tip. Here, we suggest that SOL2, together with CLV2, plays an important role in the regulation of root meristem development through the CLE signaling pathway.
