    An ethyl methanesulfonate mutagenesis was performed on clv1-1 mutant seeds to identify enhancers and/or suppressors of the Clv- phenotype. A strong modifier of clv1-1 plants was identified in this screen (pce5). The enhancing mutation was backcrossed to Landsberg erecta (Ler) and isolated. The modifier acted as a single, nuclear trait in all crosses. When combined with strong clv alleles, the enhancer led to the development of corona or ring-like meristems, leading to name the gene CORONA (CNA). The dominant-negative cna-1 allele was formerly known as pce5.

    Plants appear superficially wild type in phenotype. Altered meristem size, organogenesis, and stem cell specification. Shoot meristems of 12 day old plants are significantly larger than wild-type meristems); the effect of cna-1 on shoot meristem size in 24 day old plants is reduced compared with earlier developmental time points.
