Dominant mutations causing alterations in acetyl-coenzyme A carboxylase confer tolerance to cyclohexanedione and aryloxyphenoxypropionate herbicides in maize.
A partially dominant mutation exhibiting increased tolerance to cyclohexanedione and aryloxyphenoxypropionate herbicides was isolated by exposing susceptible maize (Zea mays) tissue cultures to increasingly inhibitory concentrations of sethoxydim (a cyclohexanedione). The selected tissue culture (S2) was greater than 40-fold more tolerant to sethoxydim and 20-fold more tolerant to haloxyfop (an...
متن کاملCharacterization of Maize Acetyl-Coenzyme A Carboxylase.
Maize (Zea mays L.) leaf acetyl-CoA carboxylase (ACCase) was purified about 500-fold by ammonium sulfate fractionation and gel filtration and blue Sepharose affinity and anion-exchange chromatography. Most ACCase activity (85%) recovered from the anion-exchange column was found in a highly purified fraction (specific activity 5.5 [mu]mol acid-stable product min-1 mg-1) that consisted primarily ...
متن کاملAn isoleucine residue within the carboxyl-transferase domain of multidomain acetyl-coenzyme A carboxylase is a major determinant of sensitivity to aryloxyphenoxypropionate but not to cyclohexanedione inhibitors.
A 3,300-bp DNA fragment encoding the carboxyl-transferase domain of the multidomain, chloroplastic acetyl-coenzyme A carboxylase (ACCase) was sequenced in aryloxyphenoxypropionate (APP)-resistant and -sensitive Alopecurus myosuroides (Huds.). No resistant plant contained an Ile-1,781-Leu substitution, previously shown to confer resistance to APPs and cyclohexanediones (CHDs). Instead, an Ile-2,...
