Interactions between nematodes and their microbial enemies in coastal sand dunes

et al. 2012

European foredunes are almost exclusively colonised by Ammophila arenaria, and both the natural succession and the die-out of this plant have been linked to populations of plant-parasitic nematodes (PPN). The overarching aim of this study was to investigate top-down control processes of PPN in these natural ecosystems through comparative analyses of the diversity and dynamics of PPN and their microbial enemies. Our specific aims were, first, to identify and quantify PPN microbial enemies in European sand dunes; second, to assess their life history traits, their spatial and temporal variation in these ecosystems, and third, to evaluate their control potential of PPN populations. This was done by seasonal sampling of a range of sites and making observations on both the nematode and the microbial enemy communities in rhizosphere sand. Nine different nematode microbial enemies belonging to different functional groups were detected in European sand dunes. Their high diversity in these low productivity ecosystems could both result from or lead to the lack of dominance of a particular nematode genus. The distribution of microbial enemies was spatially and temporally variable, both among and within sampling sites. Obligate parasites, either with low host-specificity or having the ability to form an environmentally resistant propagule, are favoured in these ecosystems and are more frequent and abundant than facultative parasites. Three microbial enemies correlated, either positively or negatively, with PPN population size: Catenaria spp., Hirsutella rhossiliensis and Pasteuria penetrans. Microbial-enemy supported links in the food-web may be involved in the control of PPN populations through indirect effects. The endospore-forming P. penetrans was the most successful top-down control agent, and was implicated in the direct control of Meloidogyne spp. and indirect facilitation of Pratylenchus spp. Overall, our findings suggest strong and diverse top-down control effects on the nematode community in these natural ecosystems.

“…Moreover, widely-used chemical products (like methyl bromide) are increasingly banned, which poses the problem of the existence of alternatives, if possible within the legal framework of organic farming. However some alternatives to chemical products do exist, which are used but present limited effects: inundation and summer solarization are two examples (Van der Putten et al 2006;Djian-Caporalino et al 2009;Collange et al 2011). Inundation causes anaerobic conditions that reduce the occurrence of RKN, but it requires a long flooding period (eight weeks) to be efficient, and causes water consumption, lack of oxygen and degradation of the soil's structure, which is not suitable to agronomic practices (Collange et al 2011).…”

“…Thus although the individual PGPR in natural systems have not received the attention they might deserve, the awareness is there that microbes are crucial in determining a plant's ability to cope with the (new) environment (Callaway et al 2004 ;Reinhart and Callaway 2006 ). A cross pollination of PGPR research and plant soil feedback could benefi t both, with natural systems as models for sustainable biocontrol (Van der Putten et al 2006 ). The applied PGPR research might benefi t from the community perspective while the plant soil feedback in natural systems can explore the space that PGPR occupy in the black box of plant soil interactions (Cortois and de Deyn 2012 ).…”

Production of plant biomass is one of the main ecosystem services delivered by soil. The area closely surrounding the root surface, the rhizosphere, is where plants interact with soil organisms. The interaction of a plant with soil microorganisms may result in several benefi ts to the plant, including improved nutrient availability or uptake, protection against pests and pathogens, improved tolerance to abiotic stress and growth promotion via hormones. Those relationships between plant and microorganisms determine plants growth and competitiveness. Ultimately the microbial community may determine plant community composition and succession. In this chapter we give an overview of fungal and bacterial microbial rhizosphere species that benefi t plants, namely plant growth promoting bacteria, mycorrhizal fungi and other benefi cial fungi. The aim is to summarize the current knowledge on mechanisms underlying plant-microbe interaction and to discuss the role of species identity and diversity for both microorganisms and plants. For each group (plant growth promoting bacteria, mycorrhiza, other benefi cial fungi) we highlight the latest developments and promising future directions. At the end of the chapter the microbial groups are viewed as part of the soil ecosystem and interactions between the groups are discussed.
