Herbicide resistant rice

InactiveUS6274796B1Growth inhibitionGood flexibilityBiocideMutant preparationRice plantsAcetohydroxy Acid Synthetase
Rice plants are disclosed with two separate, but synergistic mechanisms for resistance to herbicides that normally inhibit a plant's acetohydroxyacid synthase (AHAS) enzyme. The herbicide resistance of plants with both resistance mechanisms is substantially greater than one would expect from a simple combination of the two types of resistance. The first of the two resistance mechanisms is a metabolic pathway that is not fully understood, but that does not itself involve a mutant AHAS enzyme. The second resistance mechanism is a mutant AHAS enzyme, an enzyme that shows direct resistance to levels of herbicide that normally inhibit the enzyme, in both in vivo and in vitro assays. Besides controlling red rice, many AHAS-inhibiting herbicides also effectively control other weeds that are common in rice fields. Several of these herbicides have residual activity, so that a treatment controls both existing weeds as well as weeds that sprout later. No herbicide currently available for use on rice has residual activity against a broad spectrum of weeds including red rice. With effective residual activity against red rice and other weeds, rice producers now have a weed control system superior to those currently used.
