“…The rhizosphere of soybean plants grown in fields under long-term monoculture production systems suppressive to soybean cyst nematode were enriched for P. lilacinum and to a lesser degree P. chlamydosporia [73]. It is unclear if this is the result of selection or evolution for successful strains in this environment or a type of 'soil memory' [74]. Experimental selection for functional rhizospheres has been conducted in the lab with model plant systems [75,76].…”

“…The preceding crop (e.g., oilseed rape) may directly or indirectly affect organisms occurring in the main crop (e.g., wheat). Such effects are an example of an ecological memory effect that has frequently been reported for soil systems (Bengtsson et al, 2003;Lapsansky, Milroy, Andales, & Vivanco, 2016;Ogle et al, 2015;Peterson, 2002). From a systems perspective, ecological memory refers to the composition of species, interactions and structures that make ecosystem reorganization possible (Bengtsson et al, 2003), whereby past modifications of this composition determine the degree to which a current ecological process is shaped (Ogle et al, 2015;Peterson, 2002).…”

Agricultural landscapes are globally dominated by monocultures under intensive management. This is one of the main reasons for biodiversity loss and insect population decline in many regions all over the world. Agroecosystem biodiversity in these areas can be enhanced by cropping system diversification, such as crop rotations. Yet, long‐term studies on effects of crop rotations on aboveground agrobiodiversity are lacking. We set up a 10‐year long‐term crop rotation experiment in Central Germany and monitored the temporal dynamics of aboveground arthropods over a full cultivation period to investigate influence of current and preceding crop identity and cropping system diversification on activity density, species richness, and community structure. We found that species composition was strongly influenced by currently grown crop although effect on arthropods varied between species groups. Especially, winter oilseed rape strongly affects arthropod community structure. Interestingly, we were also able to show an influence of the preceding crops, indicating an ecological memory effect in the aboveground arthropod community. Our results show that crop identity of both currently and previously grown crops in crop rotations may lead to an increase in arthropod activity density and changes in species composition. Diversified crop rotations including appropriate crops can be an easily implemented tool to increase arthropod biodiversity and biomass at large spatial and temporal scales, particularly in areas dominated by a single crop (e.g., wheat, maize). Our results may help to design optimized crop rotations for large‐scale enhancement of insect biodiversity in agroecosystems.

“…Recently, engineering of the rhizosphere microbiome has been advocated as a promising approach to boost crop protection (Lakshmanan et al, 2014;Quiza et al, 2015). One way to achieve this is to use soil legacies in which the soil microbiome is modulated by previous crops in a way that alters the soil microbe-mediated resistance of following crops (Lapsansky et al, 2016), a principle that has been demonstrated for modulation of plant direct defense (Kostenko et al, 2012). Soils could thus be amended by inoculum from legacy-bearing soils.…”

Root symbionts: Powerful drivers of plant above‐ and belowground indirect defenses

et al. 2017

Soil microbial mutualists of plants, including mycorrhizal fungi, nonmycorrhizal fungi and plant growth promoting rhizobacteria, have been typically characterized for increasing nutrient acquisition and plant growth. More recently, soil microbes have also been shown to increase direct plant defense against above-and belowground herbivores. Plants, however, do not only rely on direct defenses when attacked, but they can also recruit pest antagonists such as predators and parasitoids, both above and belowground, mainly via the release of volatile organic compounds (i.e., indirect defenses). In this review, we illustrate the main features and effects of soil microbial mutualists of plants on plant indirect defenses and discuss possible applications within the framework of sustainable crop protection against root-and shoot-feeding arthropod pests. We indicate the main knowledge gaps and the future challenges to be addressed in the study and application of these multifaceted interactions.
