Les microalgues et cyanobactéries des sols : quels apports pour l’écotoxicologie terrestre
Les microorganismes photosynthétiques (cyanobactéries et microalgues) des sols pourraient constituer des bioindicateurs pertinents à l’égard des pressions phytosanitaires, à l’instar des milieux aquatiques. Néanmoins, les connaissances disponibles sur leur écologie dans les sols et leurs réponses aux stress sont limitées. Des développements méthodologiques (biochimiques et moléculaires) ont été réalisés afin d’identifier des marqueurs biochimiques et moléculaires pertinents pour décrire les effets de phytosanitaires sur la biomasse et la diversité des communautés microalgales. Des études en microcosmes contrôlés au laboratoire, complétés par des suivis au champ (systèmes de culture Biologiq…

Impact of Leptospermone, a Natural β-Triketone Herbicide, on the Fungal Composition and Diversity of Two Arable Soils
Impact of leptospermone, a β-triketone bioherbicide, was investigated on the fungal community which supports important soil ecological functions such as decomposition of organic matter and nutrients recycling. This study was done in a microcosm experiment using two French soils, Perpignan (P) and Saint-Jean-de-Fos (SJF), differing in their physicochemical properties and history treatment with synthetic β-triketones. Soil microcosms were treated with leptospermone at recommended dose and incubated under controlled conditions for 45 days. Untreated microcosms were used as control. Illumina MiSeq sequencing of the internal transcribed spacer region of the fungal rRNA revealed significant chang…
