DIAGSOL Development of a new functional marker for B-triketone herbicides exposure in agricultural soils
International audience; The-triketone herbicides are maize selective herbicides that have been largely applied in replacement of atrazine, banned in Europe in 2004. Their mode of action lays on the inhi- bition of the p-hydroxyphenylpyruvate dioxygenase (HPPD), a key enzyme of the carotenoid biosynthesis.In recent studies, we showed that within the soil bacterial community, many microorganisms possess a functional HPPD enzyme involved in tyrosine metabolism. These ”non-target or- ganisms” harbor the target of the-triketone herbicides and consequently may be affected in response to its exposure. From this point of view, the bacterial community harboring the hppd gene might be a relevant mark…
