Abstract
The strong correlation between glyphosate uptake and growth inhibition of cultured carrot (Daucus carota L. cv Danvers) cells incubated in the presence of aspartate suggests that aspartate reverses glyphosate inhibition of growth primarily by reducing intracellular glyphosate concentration. Other compounds which reverse glyphosate inhibition of cell growth gave a range of effects on glyphosate uptake: succinate, α-ketoglutarate, glutamate, pyruvate, and malate at 10 millimolar and phenylalanine at 2 millimolar reduced uptake by 0, 8, 11, 16, 27, and 34%, respectively. These results suggest that more than one mechanism of reversal may operate in these cells.This publication has 15 references indexed in Scilit:
