“…In the past decade, evolutionary ecology studies have documented many cases of evolution occurring on ecological time-scales [1][2][3], while community genetics research has demonstrated that the genetic identity of a focal species can affect associated community members and ecosystem processes [18,30,31]. Here, we integrate concepts from these two fields and show that rapid evolutionary responses to a novel stress associated with climate change have community-wide consequences for associated species.…”

The relative importance of rapid evolution for plant-microbe interactions depends on ecological context

Evolution can occur on ecological time-scales, affecting community and ecosystem processes. However, the importance of evolutionary change relative to ecological processes remains largely unknown. Here, we analyse data from a long-term experiment in which we allowed plant populations to evolve for three generations in dry or wet soils and used a reciprocal transplant to compare the ecological effect of drought and the effect of plant evolutionary responses to drought on soil microbial communities and nutrient availability. Plants that evolved under drought tended to support higher bacterial and fungal richness, and increased fungal : bacterial ratios in the soil. Overall, the magnitudes of ecological and evolutionary effects on microbial communities were similar; however, the strength and direction of these effects depended on the context in which they were measured. For example, plants that evolved in dry environments increased bacterial abundance in dry contemporary environments, but decreased bacterial abundance in wet contemporary environments. Our results suggest that interactions between recent evolutionary history and ecological context affect both the direction and magnitude of plant effects on soil microbes. Consequently, an eco-evolutionary perspective is required to fully understand plant-microbe interactions.

“…v www.esajournals.org Overall, our work responds to recent appeals for comparisons of the importance of genetic variation and genotypic diversity relative to other ecological factors (Hughes et al 2008, Hersch-Green et al 2011). In the S. altissima system, the effects of genetic variation were greater than that of nutrient enrichment, but this is not always the case (Orians and Fritz 1996, Mutikainen et al 2000, Stiling and Bowdish 2000.…”

“…Host-plant genotype identity and genotypic diversity account for some of the variance in the communities associated with them, but the relative importance of genetic variation and genotypic diversity compared to other ecological factors, such as environmental heterogeneity, is only beginning to be understood (Hughes et al 2008, Hersch-Green et al 2011. One key environmental factor for plants and their associated floral visitors is soil nutrient availability, as nutrients can vary considerably at a local level and are known to influence flower production and bloom duration (e.g., Campbell and Halama 1993, Asikainen and Mutikainen 2005, Munoz et al 2005, Burkle and Irwin 2009a.…”

Plant genotype, nutrients, and G × E interactions structure floral visitor communities

Abstract. Intraspecific variation in plants is driven by both genetic and environmental factors and has been shown to play an important role in determining assemblages of herbivores, predators, and pathogens. Yet, the consequences of genetic (G) and environmental (E) factors, as well as potential (G 3 E) interactions, for floral visitor communities remains poorly explored. In a common garden experiment, we compared the relative effects of host-plant genotype and genotypic diversity as well as soil nutrient enrichment on floral resource abundance and insect floral visitors associated with tall goldenrod, Solidago altissima. We found that the floral visitor community varied considerably among genotypes, driven predominantly by variation in floral phenology among S. altissima clones. Floral visitors also varied among nutrient treatments, though this response was much weaker than to different plant genotypes, and was likely driven by effects of floral rewards rather than of floral phenology. Importantly, we also detected several G 3 E interactions for both flowering and floral visitors. Taken together, our results suggest that the effects of host-plant genetic variation, and to a lesser extent G 3 E interactions, are key agents in structuring the diversity and composition of floral visitors.

“…Fagaceae species are dominant species of most temperate forest ecosystems and are drivers of terrestrial biodiversity. Interactions between trees and their associated species (mammals, fungi, and pathogens) can be tackled via gene-gene (or gene-species) interactions once candidate genes are known (Hersch-Green et al 2011). & Breeding and genetic improvement.…”

An overview of recent achievements and development of genomic resources in the Fagaceae is provided, with major emphasis on the genera Castanea and Quercus. The Fagaceae is a large plant family comprising more than 900 species belonging to 8-10 genera. Using a wide range of molecular markers, population genetics and gene diversity surveys were the focus of many studies during the past 20 years. This work set the stage for investigations in genomics beginning in the early 1990s and facilitated the application of genetic and quantitative trait loci mapping approaches. Transferability of markers across species and comparative mapping have indicated tight macrosynteny between Quercus and Castanea. Omic technologies were more recently developed and the corresponding resources are accessible via electronic and physical repositories (expressed sequence tag sequences, single-nucleotide polymorphisms, candidate genes, cDNA clones, bacterial artificial chromosome (BAC) libraries) that have been installed in North America and Europe. BAC libraries and physical maps were also constructed in Castanea and Quercus and provide the necessary resources for full nuclear genome sequencing projects that are currently under way in Castanea mollissima (Chinese chestnut) and Quercus robur (pedunculate oak).
