“…Studies found in the literature on the effect of pesticides on earthworms were conducted either under laboratory conditions (Bauer and Römbke 1997;Cathey 1982;RodriguezCastellanos and Sanchez-Hernandez 2007;Brulle et al 2010;Muthukaruppan and Paramasamy 2010) or in the field (Martin 1986;Reddy and Reddy 1992). Evaluation was achieved using different indicators that were investigated at various organisation levels.…”

“…In particular, E. fetida is the reference earthworm in international toxicity tests (Nahmani et al 2007a, b). In recent years, ecotoxicological investigations have benefited greatly from the emergence of molecular biology techniques, which lead to a better understanding of the mechanisms of contaminant action at molecular level (see Brulle et al 2010). Paradoxically, although these approaches have been widely used to better understand the effects of metals, there is almost no molecular study focusing on the effect of authorised pesticides on earthworms.…”

Earthworms provide key soil functions that favour many positive ecosystem services. These services are important for agroecosystem sustainability but can be degraded by intensive cultural practices such as use of pesticides. Many literature reports have investigated the effect of pesticides on earthworms. Here, we review those reports to assess the relevance of the indicators of earthworm response to pesticides, to assess their sensitivity to pesticides, and to highlight the remaining knowledge gaps. We focus on European earthworm species and products authorised in Europe, excluding natural compounds and metals. We consider different organisation levels: the infra-individual level (gene expression and physiology), the individual and population levels (life-history traits, population density and behaviour) and the community level: community biomass and density. Our analysis shows that earthworms are impacted by pesticides at all organisation levels. For example, pesticides disrupt enzymatic activities, increase individual mortality, decrease fecundity and growth, change individual behaviour such as feeding rate and decrease the overall community biomass and density.Insecticides and fungicides are the most toxic pesticides impacting survival and reproduction, respectively.

“…Looking at enzyme activity in different ways allows us to understand what processes are occurring without the need to identify specifi c species in the complex microbial community in soil. Brulle et al ( 2010 ) review the progress of transcriptomics as applied to soil fauna. They concentrate largely on measures of gene expression in response to metals and PAHs (polyaromatic hydrocarbons) as pollutants.…”

Interactions in Soil: Promoting Plant Growth

View full text Add to dashboard Cite

Soil is a complex milieu of physical and biological entities that regulates the availability of nutrients for plant growth. The interactions between the elements of the soil biota and the plants during this process are complex and often rely on feedbacks between the plants and the great diversity of soil organisms that function to regulate processes to support plant growth. The rhizosphere and its mycorrhizal component are important parts of the connection between the plant and soil through its roots. This zone is a 'hot-spot' of microbial activity and trophic interactions with other soil organisms. It is here that growth of the plant root is infl uenced by nutrient availability, induction of root growth stimulating auxins, the interaction with plant pathogens and herbivores. Ecosystem engineers in the form of earthworms and other burrowing fauna are important in altering both the physical structure of soil and rates of decomposition of organic residues. A little researched component of soil is viruses. Their interaction with microbial and faunal communities is introduced here. Many of the soil processes infl uencing plant growth and the diversity of soil organisms is infl uenced by human activities ranging from agricultural and forestry practices through urbanization to the infl uence of pollution from industrial processes. To help us with the understanding of the interactions between biodiversity and function, new molecular tools involving metagenomics and transcriptomics are evolving, and are discussed here as an emerging suite of tools that can be applied to soil ecology. The chapter introduces the detail to come in subsequent chapters of this book.

“…Evidence indicate that the induction of the antioxidant enzymatic system and Hsp70 may serve as potential biomarkers of environmental pollution in toxicology (Song et al, 2009;Webb and Gagnon, 2009;Xue et al, 2009;Zhang et al, 2009). Gene expression profiling is a useful supplement for protein level detection, as the mRNA level represents a snapshot of the cell activity, and has been performed to better identify biomarkers of toxicity to predict potential hazardous chemicals (Olsvik et al, 2005;Brulle et al, 2010). Previous research has detected that the gene expression of antioxidant enzymes and Hsp70 in earthworms is involved in the oxidative stress responses to heavy metals (Homa et al, 2007;Brulle et al, 2010;Xiong et al, 2014) and organic chemicals (Chen et al, 2011a,b).…”

Tetrabromobisphenol A (TBBPA), hexabromocyclododecane (HBCD) and decabromodiphenyl ether (BDE 209), suspected ubiquitous contaminants, account for the largest volume of brominated flame retardants (BFRs) since penta-BDE and octa-BDE have been phased out globally. In this paper, the growth inhibition and gene transcript levels of antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT)) and the stress-response gene involved in the prevention of oxidative stress (Hsp70) of earthworms (Eisenia fetida) exposed to TBBPA, HBCD and BDE 209 were measured to identify the toxicity effects of selected BFRs on earthworms. The growth of earthworms treated by TBBPA at 200 and 400 mg/kg dw were inhibited at rate of 13.7% and 22.0% respectively, while there was no significant growth inhibition by HBCD and BDE 209. A significant (P b 0.01) up-regulation of SOD expression level was observed in earthworms exposed to TBBPA at 50 mg/kg dw (1.77-fold) and to HBCD at 400 mg/kg dw (2.06-fold). The transcript level of Hsp70 gene was significantly up-regulated (P b 0.01) when earthworms exposed to TBBPA at concentration of 50-200 mg/kg (2.16-2.19-fold) and HBCD at 400 mg/kg (2.61-fold). No significant variation of CAT gene expression in all the BFRs treatments was observed, neither does all the target gene expression level exposed to BDE 209. Assessed by growth inhibition and the changes at mRNA levels of encoding genes in earthworms, TBBPA showed the greatest toxicity, followed by HBCD and BDE 209, consistent with trends in molecular properties. The results help to understand the molecular mechanism of antioxidant defense.
