Inhibition of ACCase activity in sensitive (00-017, ▪) and resistant
(02-F1, ▴) A. myosuroides population by clethodim and
cycloxydim (CHDs) and by fenoxaprop, diclofop, clodinafop, and haloxyfop
(APPs). ACCase from sensitive plants have Ile at positions 1,781 and 2,041,
whereas ACCase from resistant plants have Ile and Asn at positions 1,781 and
2,041, respectively. Averages of two independent experiments are shown with
error bars. ACCase activity is expressed as a percentage of ACCase activity
without inhibitor for each population.
