  1. Transmission of the p5cs2 mutant alleles was determined by sulfadiazine (p5cs2-1) or BASTA (p5cs2-2) resistance of the progeny after selfing (first three rows) or crossing of various parental genotypes.
  2. 1 A: P5CS2 wildtype allele; a1: p5cs2-1 mutant allele; a2: p5cs2-2 mutant allele; B: P5CS1 wildtype allele; b: p5cs1-4 mutant allele.
  3. 2 values are the mean ±SD of at least 3 independent plants or crossings.
  4. 3 the expected frequency takes into account that homozygous p5cs2/p5cs2 seeds are usually non-viable in the presence of wildtype or heterozygous seeds in the same silique (compare Additional file 2: Figure S2).
  5. * indicates significant difference from the expected value (p<0.03 by Χ2 test with 1 degree of freedom).
