“…Most of the attention, if not all in the fungi-earthworm interactions have been focused on arbuscular mycorrhizal fungi. In a similar way to the interaction with bacteria, the interactions between earthworms and mycorrhizal fungi, particularly arbuscular mycorrhizal fungi, have been found to modify the soil chemistry (Zhang et al, 2016(Zhang et al, , 2018 and soil nutrient availability (Milleret et al, 2009;Xiang and Li, 2014) and, critically important, the uptake of nutrients by plants (Milleret et al, 2009;Li et al, 2012Li et al, , 2013aAghababaei et al, 2014) and the composition and abundance of the fungal community (Gormsen et al, 2004;Dempsey et al, 2013;Cao et al, 2015aCao et al, ,b,c, 2016Cao et al, , 2018Zhang et al, 2016). Although the understanding of the interactions between earthworms and mycorrhizal fungi has not been the primary focus of most published works, there is a considerable amount of data that permits us to gain some insights on these interactions and their synergistic effects on plant performance (Wurst et al, 2004;Yu et al, 2005;Zaller et al, 2011;Li et al, 2013b).…”

“…These earthworm-induced "P hotspots" depend upon the earthworm species and have been shown to be larger for the epigeic L. rubellus than for the anecic L. terrestris or the endogeic A. caliginosa . The influence of earthworms on available P is particularly relevant in the rhizosphere, where earthworms can interact with arbuscular mycorrhizal fungi to enhance P solubility and transfer to the plant (Milleret et al, 2009;Cao et al, 2015a) (Box 1). Soil available P has been reported to increase in the presence of the endogeic earthworm P. corethrurus (Lopez-Hernandez et al, 1993;Chapuis-Lardy et al, 1998;Patron et al, 1999), or of epigeic E. fetida (Cao et al, 2015a), which has been linked to the enhanced microbial activity during soil ingestion or in earthworm casts, although the magnitude of the increase in available P may differ depending on earthworm functional groups (Wan and Wong, 2004;Bernard et al, 2012;Vos et al, 2014).…”

“…P fertilizers are often applied to avoid P deficiency in plants (Duminda et al 2017), but these applications have increased the accompanying risk of P losses to ground and surface waters, contributing to eutrophication (Fischer et al 2017). Moreover, P in soil exists predominantly in inorganic fractions that are either adsorbed into soil mineral surfaces or occasionally appear as available precipitates (Cao et al 2015). There is therefore an increasing need for alternative, sustainable methods that facilitate plant acquisition of P from legacy P pools.…”

Purpose The present study was designed to assess the potential effects of low-molecular-weight organic acids on the activation of inorganic phosphorus, obtain exact information on the acidity effect of proton and complex effect of organic anion in P availability, and determine the components among phosphorus fractions that contributed the most to inorganic phosphorus activation in black soil. Materials and methods Both oxalic and citric acids treated with different concentrations and pH values were carefully selected. The activating amounts of total inorganic phosphorus and individual phosphorus fractions were estimated. Path analysis was used to analyze the direct and indirect effects on inorganic phosphorus activation. Results and discussion The amount of total activating-P i increased as the concentrations of oxalic and citric acids increased. When the concentrations were ≤ 1.0 mmol L −1 , oxalic acid exhibited a lower capability than citric acid in total activating-P i , but when the concentrations were ≥ 1.5 mmol L −1 , oxalic acid exhibited a higher capability. The amount of total activating-P i decreased as pH of LMWOAs increased. LMWOAs-induced P i activation might be attributed to combine acidity and complex effects. Conclusions Correlation analysis showed that the activation of total P i was significantly correlated with the activation of H 2 O-P i , NaHCO 3-P i , NaOH-P i , and HCl-P i (p < 0.05). Path analysis revealed that soil activating-H 2 O-P i mainly affected P i activation through an indirect path. The contribution of activating-NaHCO 3-P i alone was maximal on the total activating-P i by both the direct and indirect effects, followed by activating-NaOH-P i and activating-HCl-P i .

“…Gerd. & Trappe, which could induce higher maize yields than other AM fungal species [27], is widely used in P uptake experiments for maize [28,29]. The F. mosseae M47V was obtained from the International Bank for Glomeromycota (Dijon, France) and was further propagated on white clover (Trifolium repens L.) grown in an autoclaved (121 • C for 1 h on 3 successive days) substrate for two successive propagation cycles of 4 months each.…”

Arbuscular mycorrhizal (AM) fungi can ameliorate not only plant phosphorus (P) nutrition but also soil P mobilization, while P mobilization occurs secondarily and may in turn limit P acquisition at certain crop growth stages. It can be termed as the “mycorrhiza-inducible P limitation”, which has so far largely escaped study. A pot experiment was conducted to test the dynamic P acquisition of maize (Zea mays L.) at the vegetative growth stage and P mobilization in the soil in response to AM fungal inoculation in an unsterilized arable alkaline soil. The experiment included two fertilization levels and two AM inoculation levels, i.e., nitrogen (N), P, and potassium (K) fertilization (NPK) and non-fertilization (control), as well as Funneliformis mosseae inoculation (+M) and non-inoculation (–M). Regardless of fertilization, +M increased mycorrhizal colonization and plant biomass at weeks 4 and 8 but increased tissue P concentration only at week 4 compared with those of –M. In addition, the plant P acquisition and shoot biomass in the control+M treatment at weeks 4 and 8 were close to and much lower than those of NPK–M, respectively. Furthermore, the increase in soil P mobilization potential, which was achieved by the accelerated soil alkaline phosphatase activity and the decreased soil pH, was lower than the increase in root P-acquiring efficiency, which was achieved by the enhanced mycorrhization and ZEAma;Pht1;6 (a mycorrhiza- inducible Pi transporter in maize root) expression. Regardless of fertilization, +M thus significantly decreased soil available P concentrations compared with those in the –M treatments. Therefore, there was a large, real gap between soil P mobilization and root P acquisition in response to enhanced root mycorrhizal colonization, substantially limiting plant P acquisition and growth.
