| Legumes are able to improve soil fertility via a mutualistic symbiosis with nitrogen-fixing rhizobacteria. Therefore, they represent ecologically important crops for sustainable farming systems. Besides their ecological function, grain legumes considerably contribute to the dietary protein N needs of humans (Graham and Vance 2003). Despite their importance, legume cultivation remains low due to low and unstable yields (Rubiales and Mikic 2015). Soil fatigue, also called legume yield depression syndrome, is caused by a complex of different soil-borne pathogens and thought to be the main reason for these yield losses, especially in pea (Pisum sativum) (Fuchs et al. 2014). The overall goal of this project is to improve the resistance of pea against... |

| Pea (Pisum sativum L.) belongs to the legume family (Fabaceae). Legumes form mutualistic symbiosis with nitrogen fixing rhizobacteria and, thereby, are able to improve soil fertility. Legume crops are important protein source for food and feed and contribute to the nitrogen demand of succeeding crops. Despite their importance, cultivation of cool-season legumes in temperate zones remains below expectations due to low and unstable yields. Soil fatigue is caused by a complex of different soil-borne pathogens and thought to be the main reason for yield losses, especially in pea. Plants have the ability to actively shape the community of root associated microbes through root exudations. Evidence is growing that there is considerable genetic variation for plant... |

| Disease resistance is not a mere plant but a system trait involving the complex plant-associated microbial community (Berendsen et al. 2012). As with pathogens, past research often focussed on single, culturable symbiotic microbes. More recently, microbial shifts on the community level have been linked to disease resistance. However, simplistic statements such as “high microbial diversity equals healthier plants” were not confirmed in most recent microbiome analyses (Hartmann et al. 2014, Yu et al. 2012). Plants have the ability to influence the microbial structure in the rhizosphere. Besides soil type, it has been demonstrated that not only different plant species, but also different genotypes within the same species can modify the rhizosphere microbiome... |

| Fungal root diseases severely narrow yield in pea (Pisum sativum L.) cultivation, threatening this highly valuable protein source and important crop in low input-farming systems. Adequate resistance in current pea varieties against various root pathogens is largely lacking. The control of these pathogens is challenging, as they occur as pathogen complexes in the field, themselves embeded in entangled interactions in the rhizosphere. Plants have the ability to actively shape their rootassociated microbiome and genetic variation for rhizosphere related traits exists that can potentially be harnessed in resistance breeding. Results from a controlled pot-based resistance screening of 312 pea cultivars, advanced breeding lines and gene bank accessions on... |

| Plant-associated microbial communities play a crucial role for the expression of various plant traits including disease resistance. Increasing evidence suggests that host genotype influences the composition and function of certain microbial key groups, which, in turn, effects how the plant reacts to environmental stresses. Several studies indicate that modern plant breeding may have selected against plant traits essential for hosting and supporting beneficial microbes. However, they also highlight the presence of an exploitable genetic base for the regulation of the rhizosphere microbiota. We illustrate the concept of breeding for microbial symbioses with pea (Pisum sativum L.). Firstly, genotypic variation for the efficiency of a mycorrhizal symbiosis is... |

| Pea (Pisum sativum L.) is a valuable protein source for food and feed. Pea is able to significantly improve soil fertility and, hence, represents an ecologically important crop in low-input farming systems. Despite their importance, pea cultivation remains below expectations due to low and unstable yields caused by a complex of soil-borne pathogens. The goal of this project is to improve our understanding of resistance mechanisms of pea against soil-borne diseases. To achieve this goal, more than 300 pea lines were evaluated for resistance in pot-experiments and a subset of susceptible and resistant pea genotypes has been identified. In a next step, key pathogens and beneficials in the pea rhizosphere and the role of root exudates in determining the... |
