  • a F1 plants were scored under UV, 7–14 days after planting.

  • b ref1-3 (WS ecotype) was isolated from a screen of 65,000 T-DNA mutagenized lines.

  • c ref2-2, ref2-3, and ref2-4 (Columbia ecotype) were isolated in separate screens of EMS-mutagenized seeds (J. Humphreys and C. Chapple, unpublished results).

  • d ref3-1 (Ler ecotype) was isolated separately from EMS-mutagenized seed (C. Chapple and C. R. Somerville, unpublished results).

  • e ref3-4/ref3-4 is sterile. The chi-square value for an expected wild type:mutant ratio of 1:1 is 2.00 (P ≥ 0.05).
