Regulation of Tobacco Acetolactate Synthase Gene Expression [PDF]
Plant Physiology, 1993 Acetolactate synthase (ALS) catalyzes the first common step in the biosynthesis of isoleucine, leucine, and valine. The previous cloning of two tobacco (Nicotiana tabacum) ALS genes (SurA and SurB) has allowed transcript accumulation from these genes to be monitored. mRNA blot analysis of ALS transcripts showed a message size of 2.2 kb. Quantitation of

Resistance of Amaranthus retroflexus to acetolactate synthase inhibitor herbicides in Brazil [PDF]
Planta Daninha, 2014 When in competition with cotton, Amaranthus retroflexus can cause high yield losses. Due to the limited availability of selective herbicides registered for post emergence control of this weed, the same herbicides have been used repeated times over the ...

Microbial Cell Factories, 2019 Background Diacetyl provides the buttery aroma in products such as butter and margarine. It can be made via a harsh set of chemical reactions from sugarcane bagasse, however, in dairy products it is normally formed spontaneously from α-acetolactate, a ...

Resistence of Radish Biotypes to Iodosulfuron and Alternative Control [PDF]
Planta Daninha, 2016 The repetitive use of iodosulfuron for the control of weeds in winter cereals in the south of Brazil has favored the emergence of resistant Raphanus sativus biotypes.

Response of Herbicide-Resistant Palmer Amaranth (Amaranthus palmeri) Accessions to Drought Stress
International Journal of Agronomy, 2013 Palmer amaranth is a very problematic weed in several crops in the southern USA due to its competitive ability and resistance to herbicides representing different mechanisms of action.

Field and laboratory assessments of sugarcane mutants selected in vitro for resistance to imazapyr herbicide [PDF]
Crop Breeding and Applied Biotechnology, 2017 Seven imazapyr-tolerant mutant sugarcane plants, previously generated by in vitro mutagenesis, were studied. The imazapyr concentrations required to inhibit their acetolactate synthase (ALS basal activity) (IC50 as μmoles acetoin h-1 mg-1 protein) were 0.

BMC Plant Biology, 2018 Background Weed management is critical to global crop production and is complicated by rapidly evolving herbicide resistance in weeds. New sources of herbicide resistance are needed for crop plants so that applied herbicides can be rotated or combined to
