1. Respostas de Crescimento de Plantas de Maçã e Pera a Doses de Glyphosate
RESUMO Glyphosate é comumente usado para manejo de plantas daninhas na linha de plantio de culturas perenes, onde a exposição não intencional da cultura a esse herbicida pode causar redução do crescimento. O objetivo desta pesquisa foi analisar o comportamento do crescimento inicial de plantas jovens de maçã e pera expostas ao glyphosate. Glyphosate

2. Non-Thermal Plasma Induced Total Mineralization of Glyphosate in Water in the Presence of Iron II Ions
The present work focused on the mineralization of herbicide glyphosate (N-(phosphonomethyl) glycine) (C3H8NO5P) in aqueous phase by Glidarc plasma following the orthophosphates released and the reduction of the total organic carbon (TOC). Furthermore, the effect of initial concentration, pH and the degradation process of glyphosate in the presence of Fe2+ we

3. Efeito in vitro do herbicida glifosato na agregação plaquetária e coagulação sanguínea em humanos
O glifosato [N-(phosphonomethyl)-glycine] é um herbicida pós-emergente não seletivo de amplo espectro muito utilizado na agricultura. Dados da literatura referentes aos efeitos desse produto na saúde humana são contraditórios. Em estudos prévios demonstramos que ratos previamente tratados com glifosato apresentavam lesões hepáticas e sangramento sem

4. Estudo de recuperação de glifosato e AMPA derivados em solo utilizando-se resinas nacionais
In the present paper we studied the recoveries of glyphosate, N-(phosphonomethyl)glycine (GLY) and its major metabolite, (aminomethyl)phosphonic acid (AMPA) in soil using national (Brazilian) ion-exchange resins, derivatization by a mixture of trifluoroacetic anhydride and trifluoroethanol and analyses by GC-MS. The quantification limits were 12 ng.g-1 for b

5. The Site of the Inhibition of the Shikimate Pathway by Glyphosate: I. INHIBITION BY GLYPHOSATE OF PHENYLPROPANOID SYNTHESIS IN BUCKWHEAT (FAGOPYRUM ESCULENTUM MOENCH) 1, 2
The nonselective herbicide glyphosate (n-[phosphonomethyl]glycine) inhibited the light-induced accumulation of phenylpropanoid substances (chlorogenic acid, procyanidin, rutin, anthocyanin) in etiolated buckwheat hypocotyls 90% at 1 millimolar. Structurally related compounds, such as n,n-bis[phosphonomethyl]glycine, aminomethylphosphonate, methylglycine, and

6. Degradation of the Phosphonate Herbicide Glyphosate by Arthrobacter atrocyaneus ATCC 13752
Of nine authentic Arthrobacter strains tested, only A. atrocyaneus ATCC 13752 was capable of using the herbicide glyphosate [N-(phosphonomethyl)glycine] as its sole source of phosphorus. Contrary to the previously isolated Arthrobacter sp. strain GLP-1, which degrades glyphosate via sarcosine, A. atrocyaneus metabolized glyphosate to aminomethylphosphonic ac

7. Uptake of Glyphosate by an Arthrobacter sp
The uptake of glyphosate (N-[phosphonomethyl]glycine) by an Arthrobacter sp. which can utilize this herbicide as its sole source of phosphorus was investigated. Orthophosphate suppressed the expression of the uptake system for glyphosate and also competed with glyphosate for uptake. The Km for glyphosate uptake was 125 μM, and the Ki for orthophosphate was

8. Effect of Glyphosate on Carrot and Tobacco Cells 1
The growth of suspension-cultured carrot (Daucus carota L.) and tobacco (Nicotiana tabacum L. cv. Xanthi) cells was inhibited by glyphosate (N-[phosphonomethyl]glycine). This inhibition was reversed by adding combinations of phenylalanine, tyrosine, and tryptophan or casein hydrolysate. Casein hydrolysate and phenylalanine + tyrosine + tryptophan were the mo

9. Isolation and Characterization of a Mutant of Arthrobacter sp. Strain GLP-1 Which Utilizes the Herbicide Glyphosate as Its Sole Source of Phosphorus and Nitrogen
Arthrobacter sp. strain GLP-1, grown on glucose as a carbon source, utilizes the herbicide glyphosate [N-(phosphonomethyl)glycine] as its sole source of phosphorus as well as its sole source of nitrogen. The mutant strain GLP-1/Nit-1 utilizes glyphosate as its sole source of nitrogen as well. In strain GLP-1, Pi was a potent competitive inhibitor of glyphosa

10. Effect of Glyphosate on Intact Bean Plants (Phaseolus vulgaris L.) and Isolated Cells 1
Whole bean (var. “Eastern Butterwax”) plants and isolated cells were used to investigate possible mechanisms of action of glyphosate [N-(phosphonomethyl)glycine]. Results showed that glyphosate was quickly absorbed by the whole plant but not by individual cells and that it caused a rapid reduction in leaf dry matter accumulation, leaf expansion, leaf ang

11. The Site of the Inhibition of the Shikimate Pathway by Glyphosate: II. INTERFERENCE OF GLYPHOSATE WITH CHORISMATE FORMATION IN VIVO AND IN VITRO1
In the presence of the nonselective herbicide glyphosate (N-[phosphonomethyl]glycine), buckwheat (Fagopyrum esculentum Moench) hypocotyls and cultured cells of Galium mollugo L. accumulate an organic acid, which was identified as shikimate by mass-spectroscopy of its methyl ester. After growth in 0.5 millimolar glyphosate for 10 days, G. mollugo cells contai

12. Apoplastic and Symplastic Pathways of Atrazine and Glyphosate Transport in Shoots of Seedling Sunflower 1
[14C]Atrazine (2-chloro-4-[ethylamino]-6-[isopropylamino]-s-triazine) and [14C]glyphosate (N-[phosphonomethyl]glycine) were xylem fed to sunflower shoots at 100 micromolar for 1 hour in the light, then placed in the dark at 100% relative humidity for 1, 4, 7, or 10 hours. The distribution of atrazine and glyphosate between shoot parts, in the leaves, and bet
