Suppression of vcs is conferred by At1g77680 encoding a proline at position 705. (A) The effect of SOV genomic clones transformed into the wild-type and vcs-7 mutants; only SOV encoding PRO-705 confer the partially rescued vcs phenotype. Transgenic wild-type carrying SOV^L.er appear normal, and vcs-7 carrying SOV^L.er appear indistinguishable from vcs-1. This partially suppressed vcs-1 phenotype is mostly easily seen by the presence of leaves and green organ color. The partial suppression required the L.er version of SOV because vcs-7 transgenic plants carrying an extra copy of SOV^Col-0 were not suppressed unless SOV^Col-0 had been modified to resemble the L.er version at amino acid 705. (B) Rescue constructs designed to test the importance of PRO at position 705 and used in the experiments shown in A.
