Feeding a growing world population amidst climate change requires optimizing the reliability, resource use, and environmental impacts of food production. One way to assist in achieving these goals is integrate beneficial plant microbiomes—i.e., those enhancing growth, nutrient use efficiency, abiotic stress tolerance, disease resistance—into agricultural This integration will require large-scale effort among academic researchers, industry farmers understand manage plant-microbiome...
Plants simultaneously interact with multiple organisms which can both positively and negatively affect their growth. Herbivores reduce plant growth through loss of biomass photosynthetic area, while mutualists, such as mycorrhizal fungi, increase uptake essential nutrients. This is the first study examining whether species-specific associations fungi alter tolerance to herbivory. We grew Plantago lanceolata plants three species previously shown have differential impacts on subjected them...
Plants are important mediators of interactions between their associated microbe and insect communities (Van der Putten et al. 2001; Ohgushi 2005). Changes in plants induced by one species have cascading effects on with other species, shaping abundances community structure (Ohgushi 2008). While the consequences such indirect for predominantly been examined within plant-associated (e.g. Van Zandt & Agrawal 2004; Poelman 2008; Utsumi 2011), there is growing evidence that similar community-wide...
Abiotic stress is a widespread threat to both plant and soil communities. Arbuscular mycorrhizal (AM) fungi can alleviate effects of abiotic by improving host tolerance, but the direct on AM are less well understood. We propose two hypotheses predicting how will respond stress. The exclusion hypothesis predicts that fungal abundance diversity decrease with persistent adaptation evolve in response maintain their fitness. conclude have independent plant. communities change composition stress,...
Abstract There is tremendous diversity of interactions between plants and other species. These relationships range from antagonism to mutualism. Interactions with members their ecological community can lead a profound metabolic reconfiguration the plants’ physiology. This favour beneficial organisms deter antagonists like pathogens or herbivores. Determining cellular molecular dialogue plants, microbes, insects, its evolutionary implications important for understanding options each partner...
Summary 1. Plant communities are generally thought to follow strict competitive hierarchies, in which species can be linearly ordered according their ability compete for a few limiting resources. Such hierarchies should lead reduced diversity, since the single best competitor will eventually exclude other species. However, more complex dynamics may emerge if different plant or genotypes ways, such as through release of toxic allelochemicals alteration soil microbial communities. 2. Brassica...
Abstract Climate change is shifting the distribution of species, and may have a profound impact on ecology evolution species interactions. However, we know little about increasing temperature changing rainfall patterns interactions between plants their beneficial antagonistic root symbionts. Here, used reciprocal multifactorial growth chamber experiment with seeds soil microbial communities from three origins to investigate moisture growth, arbuscular mycorrhizal (AM) fungal colonization...
Abstract Future climate scenarios predict changes in rainfall regimes. These are expected to affect plants via effects on the expression of root traits associated with water and nutrient uptake. Associated microorganisms may also respond these new precipitation regimes, either directly response soil environment or indirectly altered trait expression. We characterized arbuscular mycorrhizal (AM) fungal communities an Australian grassland exposed experimentally used Illumina sequencing assess...
Trait-based approaches in ecology are powerful tools for understanding how organisms interact with their environment. These show particular promise disturbance and community contexts disturbances like prescribed fire bison grazing influence interactions between mutualists arbuscular mycorrhizal (AM) fungi plant hosts. In this work we examined effects on AM fungal spore composition mutualisms were mediated by selection specific functional traits at both the species level. We tested these...
To date, few analyses of mutualistic networks have investigated successional or seasonal dynamics. Combining interaction data from multiple time points likely creates an inaccurate picture the structure (because these are aggregated across time), which may negatively influence their application in ecosystem assessments and conservation. Using a replicated bipartite network arbuscular mycorrhizal (AM) fungal-plant associations, detected using large sample numbers plants AM fungi identified...
Invasive plants represent a significant threat to ecosystem biodiversity. To decrease the impacts of invasive species, major scientific undertaking last few decades has been aimed at understanding mechanisms that drive plant success. Most studies and theories have focused on single mechanism for predicting success therefore cannot provide insight as relative importance multiple interactions in species' success.We examine four potentially contribute velvetgrass Holcus lanatus: direct...
Abstract Climate models project overall a reduction in rainfall amounts and shifts the timing of events mid‐latitudes sub‐tropical dry regions, which threatens productivity diversity grasslands. Arbuscular mycorrhizal (AM) fungi may help plants to cope with expected changes but also be impacted by changing rainfall, either via direct effects low soil moisture on survival function or indirectly plant community. In an Australian mesic grassland (former pasture) system, we characterized AM...
