Gene of non-target microorganisms : a new tool to monitor the exposure of soil microbial communities to b-triketone herbicides ?
International audience; β-triketone herbicides are among the most used herbicides in corn crop. These herbicides inhibit the 4-hydroxyphenylpyruvate dioxygenase (4-HPPD), lead to bleaching and prevent the growth of broadleaf weeds. This enzyme is not only found in plants but in all living organisms, including microorganisms where it plays a role in the tyrosine degradation pathway. Thus, microorganisms classified as “non-target organisms” by current EU regulation for pesticide authorization, might be impacted by β-triketones, with consequences on microbial function supporting soil ecosystem services. Since microorganisms have been proposed by EFSA as key-drivers to protect soil ecosystem se…
