 Both cpr1 and cpr30 are alleles of At4g12560. (A) Western blot analysis of SNC1 protein levels in cpr1 (renamed cpr1-1), cpr30-1 (renamed cpr1-2), and cpr30-2 (renamed cpr1-3). snc1-r1 (a loss-of-function deletion allele of SNC1), WT, and snc1 plants were used as controls. (B) Allelism test between cpr30-2 and cpr1. Morphology of two F1 plants from the cross between cpr30-2 and cpr1, with WT, cpr30-2, and cpr1 plants as controls. (C) Complementation of cpr1-1 by the CPR1 transgene under 35S promoter. Morphologies of two independent transgenic lines (T1-2 and T1-4) are shown.
