“…This would account for the higher N content of ears in the presence of earthworms. This positive effect of earthworms on plant N content has been reported in previous studies (Eisenhauer and Scheu, 2008;Jana et al, 2010;Zhang et al, 2010). We also found that root N content was lower in the presence of earthworms, indicating that earthworms also influence the translocation of N within the plant (Quaggiotti et al, 2004).…”

“…The greater availability of nutrients in the presence of earthworms, due to greater organic matter mineralization, may account for the lower level of investment in root biomass (Laossi et al, 2010;Jana et al, 2010). This lower level of investment in root biomass would be expected to lead to a greater investment in aerial biomass, but no such increase was observed here.…”

trol of eyespot disease on two winter wheat cultivars by an anecic earthworm (Lumbricus terrestris). Applied Soil Ecology, Elsevier, 2015Elsevier, , 96, pp.33 -41. <10.1016Elsevier, /j.apsoil.2015 Eyespot is a major fungal disease of winter wheat, mostly affecting the base of the stem. The development of biological control approaches, using organisms such as earthworms, represents a potential alternative strategy for eyespot control. In a greenhouse experiment, we analyzed the response of two wheat cultivars (Soissons and Aubusson) to the presence of the pathogenic fungus Oculimacula yallundae and the anecic earthworm Lumbricus terrestris, alone and in combination. We assessed necrosis frequency, necrosis severity, wheat biomass, resource allocation and soil mineral concentrations. Disease incidence was lower in the presence of earthworms: the frequency of necrosis was 44% lower for Soissons and 70% lower for Aubusson. Necrosis severity was also lower for both cultivars (50% lower for Soissons and 80% lower for Aubusson) in the presence of earthworms. Earthworms had no detectable effect on the shoot and root biomasses of plants exposed to the fungus, but they modified resource allocation between plant organs and nutrient translocation within the plant. Our results suggest that earthworms are a potentially effective biocontrol agent for eyespot, and we discuss the possible underlying mechanisms.

“…Esta respuesta se atribuye al efecto osmótico que se origina en la solución salina, misma que dificulta el régimen hídrico de las plantas y al efecto tóxico de los iones que interfieren en procesos metabólicos como la síntesis de carbohidratos y el transporte de productos fotosintéticos, así como su utilización en la producción de nuevos tejidos, además de un efecto positivo en los componentes microbiológicos (Gutiérrez et al, 2008), fitohormonas (Jana et al, 2010), iones disponibles (Sallaku et al, 2009) y modificación de las propiedades físico-químicas del suelo (Azarmi et al, 2008).…”

“…The release of nutrients due to this dual interaction has consequences on plant growth [4][5][6]. In addition to nutrients, interdependence between microorganisms, plants, and earthworms has led to the selection of diversified signal molecules, from low-molecular weight compounds such as auxin (e.g., IAA), amino acids, and secondary metabolites, to high-molecular weight compounds such as proteins and polysaccharides (for review see [7]).…”

Some soil microorganisms are involved in the complex interactions with plants and earthworms, through the production of indole acetic acid (IAA) which modifies plant growth and development. In a factorial experiment testing the impact of the presence/absence of plants and earthworms on IAA production by cultivable bacteria, we observed that plants were decreasing IAA production of 43%, whereas earthworms were increasing it of 46%. In the presence of both plant and earthworms, IAA production was as low as in the presence of plant control, showing that plants influence on IAA production by microorganisms prevails on earthworm influence. We discuss functional reasons which could explain this result.
