“…AMF rely on their host plant to fulfil their entire C requirements (Smith & Read, 2008 ). In nature, neighbouring plants within communities are typically interconnected by common mycelial networks (CMNs) of shared AMF hyphae (Alaux et al ., 2021 ). AMF‐acquired nutrients and plant‐fixed C are distributed throughout these networks (Robinson, 1999 ; Bücking et al ., 2016 ), reducing the reliance of AMF on individual plant hosts for plant C. In this way, plant communities may not only share the benefits of AMF symbionts but also share, and thereby mitigate, the cost of symbiosis and the burden of pests through mobilization and redistribution of resources through the network (Bücking et al ., 2016 ).…”

“…In this way, plants infected with PCN may still benefit from AMF associations in terms of nutrient gains, but the C demand of AMF may be fulfilled by neighbouring plants from across the network. This strategy, together with the ability of the CMNs to transmit plant defence signals to neighbouring plants (Babikova et al ., 2013 ), could help enhance resilience against pests and pathogens in plant communities in both natural and agroecosystems (Alaux et al ., 2021 ). The host also may interact with multiple AMF taxa simultaneously (Chen et al ., 2017 ), which may impact plant defence responses and C : N exchange.…”

Disruption of carbon for nutrient exchange between potato and arbuscular mycorrhizal fungi enhanced cyst nematode fitness and host pest tolerance

et al. 2022

Summary Plants simultaneously interact with a range of biotrophic symbionts, ranging from mutualists such as arbuscular mycorrhizal fungi (AMF), to parasites such as the potato cyst nematode (PCN). The exchange of mycorrhizal‐acquired nutrients for plant‐fixed carbon (C) is well studied; however, the impact of competing symbionts remains underexplored. In this study, we examined mycorrhizal nutrient and host resource allocation in potato with and without AMF and PCN using radioisotope tracing, whilst determining the consequences of such allocation. The presence of PCN disrupted C for nutrient exchange between plants and AMF, with plant C overwhelmingly obtained by the nematodes. Despite this, AMF maintained transfer of nutrients on PCN‐infected potato, ultimately losing out in their C for nutrient exchange with the host. Whilst PCN exploited the greater nutrient reserves to drive population growth on AMF–potato, the fungus imparted tolerance to allow the host to bear the parasitic burden. Our findings provide important insights into the belowground dynamics of plant–AMF symbioses, where simultaneous nutritional and nonnutritional benefits conferred by AMF to hosts and their parasites are seldom considered in plant community dynamics. Our findings suggest this may be a critical oversight, particularly in the consideration of C and nutrient flows in plant and soil communities.

“…Common mycorrhizal networks (CMN) also play a role in linking plants together (Alaux et al, 2021). These are formed by mycorrhizal fungi which make up a complex and dense network of mycelium in soil allowing the plant's roots to access otherwise inaccessible soil.…”

“…These are formed by mycorrhizal fungi which make up a complex and dense network of mycelium in soil allowing the plant's roots to access otherwise inaccessible soil. This network allows for an exchange of nutrients and water affecting plant resistance and tolerance to stresses (Alaux et al, 2021). There is evidence that sustainable agricultural practices, such as agroforestry, have a positive effect on CMNs (Battie-Laclau et al, 2020;Alaux et al, 2021).…”

A review of agroforestry, precision agriculture, and precision livestock farming—The case for a data-driven agroforestry strategy

et al. 2022

Agroforestry can be defined as an agroecosystem whereby soil is used holistically and synergistically by various stakeholders including farmers, livestock, and plants. As such, agroforestry offers numerous benefits that include conservation of biodiversity, regulation of pests and diseases, increased quality of soil, air and water, efficient cycling of nutrients, and resilience to climate change. Review of published studies in agroforestry shows however that research in this area could benefit from increased real-time, spatial and temporal measurements. This situation is to be contrasted with that of precision agriculture in monocultures and precision livestock farming where progress made in sensor systems has attracted considerable research interest. It is advocated in this review article that wireless sensor networks could also significantly impact agroforestry through the monitoring of the local real-time interactions that occur between the various components constituting agroforestry systems. This review article proposes therefore the new field of data-driven agroforestry which lies at the intersection of precision agriculture, precision livestock farming, permaculture, and agroforestry. Data-driven agroforestry has the potential to not only help farmers harness the interactions between the different components of an agroforestry system to their advantage but also shine light on fundamental interactions between soil, plants, trees, and livestock while offering a sustainable agricultural method beneficial to all agroforestry stakeholders.

“…Arbuscular mycorrhizal fungi (AMF) form a mutually symbiotic with the roots of land plants and play an important role in regulating community and ecosystem functioning (Wu et al, 2021). Mycorrhizal fungi are important in agriculture and forestry as bidirectional nutrient transfer between host and fungal endophyte (i.e., drain of host carbon and uptake of soil mineral drive many nutrient cycling processes in soil) (Xavier and Germida, 1999;Alaux et al, 2021). In community with decreased mycorrhizal fungi, weed species that are characterized by non-mycorrhizal relationships increase and the nutrient cycle can be broken.…”

Tomato is one of the important food crops of the world. It has rich essential nutrients features. However, tomato plants are sensitive to certain diseases and pests. This situation causes intense and unconscious pesticide use to avoid crop losses. It is known that mycorrhiza provide many advantages to plant. In this study, the effects of different doses of fungicide applications on some physiological parameters were examined in mycorrhiza applied and non-applied mycorrhiza tomato plants. A pesticide was applied at different doses which were, namely, recommend (R), half of recommend (R/2), and two-fold recommend (R×2). The content of proline, chlorophyll and carotenoid analysis were conducted in the plant samples. Proline values were found low in mycorrhizal than non-mycorrhizal plants in all pesticide doses (P
