The enzyme AHAS (acetohydroxy acid synthase), which is involved in the biosynthesis of valine, leucine and isoleucine, is the target of several classes of herbicides. A model of tobacco AHAS was generated based on the X-ray structure of yeast AHAS. Well conserved residues at the herbicide-binding site were identified, and the roles of three of these residues (Phe-205, Val-570 and Phe-577) were ...

Abstract Herbicide resistance is one of the main crop traits that improve farming methods and productivity. CRISPR-Cas9 can be applied to development herbicide-resistant crops based on a target site mechanism, by editing genes encoding herbicide binding proteins. The sgRNAs capable herbicides, pds (phytoene desaturase), ALS (acetolactate synthase), EPSPS (5-Enolpyruvylshikimate-3-phosphate were...

The decomposition of seven herbicides (atrazine, linuron, lenacil, chloridazon, dinoseb acetate, prometryn, and diuron) was carried out by detonative combustion. investigated blasting material produced on the basis porous ammonium nitrate, which served as an oxidizer, while pesticides played role fuel. Detonative mixtures in blast-holes soil. efficiency process assessed using techniques gas chr...

chlorophyll fluorescence induction is a rapid and noninvasive technique for measuring photosynthetic electron transport in plants. chlorophyll fluorescence measurements were performed under greenhouse condition to characterize how the fluorescence induction curves (kautsky curve) and its parameters were affected by metribuzin in susceptible and resistant junglerice (echinochloa colona (l.) link...

It has been previously shown that certain herbicides or plant extracts inhibited the viral infection. The goal of this study was to investigate the effect of Obuda pepper virus (ObPV) infection and herbicide or plant extract treatments on the photosynthetic processes of the host plants to get informations about the interactions of these factors. In Capsicum annuum-ObPV host-virus relations the ...

Gene flow exposed by genetically engineered crops Gene flow is the transfer of genes between populations of the same or related species. The exchange between crop cultivars of genes selected by traditional breeding that confer characteristics such as shorter stems, higher yield, or increased seed quality will attract little attention. In the same way, crop-weed hybrids having acquired traits su...

Abstract The objective of this work was to evaluate the effects application glyphosate herbicide on seed reserve mobilization and seedling morphology genetically modified soybean. Two herbicide-tolerant (TMG 1264RR P98Y11) two herbicide-sensitive (Emgopa 315 UFUS 7415) cultivars were selected for study subjected germination, length, tests after treatments with solutions at concentrations 0.00, ...

Aim. This work is devoted to the search for potential partners integrated application of flumioxazine in sunflower crops. herbicide an inhibitor protoporphyrinogen oxidase (PPO) weed plants. The resistance this class herbicides not yet common today, compared other classes. Therefore, aimed at de- veloping flumioxazine-based compositions that effectively prevent emergence herbicide-resistant bio...
