Abstract

The effect of the herbicide imazamethabenz-methyl (IMZM), a mixture of the two isomers methyl (±)-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-4-methylbenzoate (para isomer) and methyl (±)-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-5-methylbenzoate (meta isomer), on the uptake of nitrate by wheat grown hydroponically was studied. IMZM stimulates the nitrate uptake in both “induced” (NO3--pretreated) and “uninduced” (NO3--starved) seedlings, most likely as a response to a plant stress. The decrease in acetohydroxy acid synthase (AHAS; EC 4.1.3.18) activity and in protein content of IMZM-treated roots supports this hypothesis. The presence of valine, leucine, isoleucine, and IMZM prevents the effects of the herbicide treatment in both induced and uninduced plants. The addition of IMZM to humic acid enhances the nitrate uptake, although to a lower extent than with the herbicide alone. Possible traces of imazamethabenz acid (IMZA) in growing units do not seem to be ...

Role of oxidative stress in the physiology of sensitive and resistant Amaranthus palmeri populations treated with herbicides inhibiting acetolactate synthase

Oxidative stress plays a role in the mode of action of ALS inhibitor herbicides, with sensitive Amaranthus palmeri plants showing increased oxidative stress and resistance plants not showing these responses.

Analysis of the Photodegradation of the Imidazolinone Herbicides Imazamox, Imazapic, Imazaquin, and Imazamethabenz-methyl in Aqueous Solution.

Imazamox and imazapic herbicides degrade more rapidly than imazaquin at all pH values, with higher quantum yields, while imazaquin shows no trend as a function of pH.

Addition reactions to chiral aziridine-2-carboxaldimine toward various enantiopure nitrogen-containing heterocycles

Chiral aziridine-2-carboxaldimine can be used to prepare enantiopure nitrogen-containing heterocycles through stereoselective addition reactions with organomagnesium reagents, cyanotrimethylsilane, and ketene acetal.

Net Nitrate Uptake by the Roots of Different Potato Haploids

Potato haploids show high variability in nitrate acquisition efficiency, which must be assessed to select varieties with improved nitrate uptake capacity.

Influence of coumarin on the net nitrate uptake in durum wheat

Coumarin stimulates nitrate uptake and translocation in durum wheat seedlings, potentially due to its effects on root vessel size.
