NOTES

1. Amino acid number is standardized to the Arabidopsis thaliana sequence

2. The letters indicate the level of resistance conferred by the mutation
  • S = Susceptible biotype
  • r = Moderate resistance (< 10-fold relative to sensitive biotype)
  • R = High Resistance (> 10-fold)
  • ND = Not Determined
It should be noted that these classifications are generalizations.

3. The year that the mutation was first reported: see details for reference.
HERBICIDE FAMILY ABBREVIATIONS

PTB = Pyrimidinyl benzoates
IMI = Imidazolinones
SCT = Triazolinones
SU = Sulfonylureas
TP = Triazolopyrimidine - Type 1
