Breeding for microbiome-mediated disease resistance Organic Eprints
Hohmann, Pierre; Wille, Lukas; Studer, Bruno; Bodenhausen, Natacha; Messmer, Monika.
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...

Breeding for Mixed Cropping and Anthracnose Resistance of Lupins Organic Eprints
Arncken, Christine; Hohmann, Pierre; Messmer, Monika.
Introduction In Switzerland, the organic sector has been trying to reduce the massive import of protein crops for feed by encouraging grain legume cultivation during the past years (Clerc et al, 2015). The main limiting factors of low yield stability and high weed pressure were successfully overcome through intercropping of peas and faba beans with barley and oats, respectively. Thus, the production of peas and faba beans grew continuously from 2010 to 2015 from 200t and 90t to 1170t and 560t, respectively (bioaktuell 2017). For more diversification of domestic grain legume cultivation and supply, FiBL has started field trials with blue (Lupinus angustifolius) and white lupins (L. albus) in 2014. The high risk of anthracnose, caused by the fungal agent...

Breeding for mycorrhizal symbiosis: focus on disease resistance Organic Eprints
Hohmann, Pierre; Messmer, Monika.
Modern plant breeding can no longer afford to ignore the interaction between plants and microbial key players. Increasing evidence suggests (i) that the expression of many plant traits (such as nutrient use efficiency or tolerances against biotic and abiotic stresses) is mediated by beneficial microorganisms and (ii) that there is an exploitable genetic base for the regulation of symbiotic relationships. Arbuscular mycorrhizal fungi (AMF) play a key role in many of these trait expressions. While much is known about their ability to mobilise nutrients (especially phosphorus), the complex mechanisms of AMF-mediated disease resistance have only started to become apparent within the past decade. Besides competition for root space and resources, AMF also have...

Breeding for symbioses – Mycorrhizae as a case study Organic Eprints
Hohmann, Pierre; Backes, Gunter; Thonar, Cécile; Messmer, Monika.
Plant associated soil microbes are known to play an important role in the expression and stability of certain plant traits such as nutrient use efficiency and disease resistance. Arbuscular mycorrhizal fungi (AMF) form one of the primary mutualistic plant-microbe symbioses. Besides known benefits such as improved nutrient mobilisation (mainly phosphorus and zinc) and tolerance against abiotic stresses (mainly drought), an increasing number of studies highlight a significant role of AMF in the mediation of disease resistances and priming mechanisms. Individual reports have shown enhanced levels of defence-related compounds (such as glucanases, chitinases and phenolics) in mycorrhizal plants, and there is first evidence of certain phytohormone pathways (in...

Breeding strategies for a spring barley pea mixed cropping system Organic Eprints
Haug, Benedikt; Messmer, Monika M.; Enjalbert, Jérôme; Goldringer, Isabelle; Forst, Emma; Mary-Huard, Tristan; Hohmann, Pierre.
Introduction and methods Crop mixtures of cereals and legumes have received recent attention in the scope of climate change and local protein supply. Cereal-legume mixtures are known to increase yield and yield stability compared with pure crops. Thus dedicated breeding strategies for mixed cropping might become necessary. As a model crop, we compared 32 current European spring pea (Pisum sativum L.) and 8 current spring barley (Hordeum vulgare L.) cultivars for their yield performance in mixed and pure stands, with pea as the focal species. Trials were done as an incomplete factorial design (Fig. 1) at two locations in Switzerland with two replications (Fig. 2). We calculated variance components for the general and specific mixing ability (GMA and...

Development of genetic models to breed for mixed cropping systems Organic Eprints
Haug, Benedikt; Messmer, Monika; Forst, Emma; Mary-Huard, Tristan; Enjalbert, Jérôme; Goldringer, Isabelle; Hohmann, Pierre.
Introduction Mixed cropping, i.e. mixing different crops in the same field, provides agronomic advantages as increased productivity under low inputs conditions (e.g. for organic farming: Bedoussac et al. 2015) and higher yield stability (Raseduzzaman and Jensen 2017). In mixed cropping, choosing the right cultivars is critical for the performance of the mixture, as shown for pea-barley mixtures (Hauggaard-Nielsen and Jensen 2001) and maize-bean mixtures (Hoppe 2016). As performance in pure stand can strongly diverge from performance in mixture, estimating the ability of a cultivar to be mixed with another crop is therefore of utmost importance. For this purpose, concepts of General and Specific Combining Ability in hybrid breeding (Griffing 1956) have...

Ecological studies of the bio-inoculant Trichoderma hamatum LU592 in the root system of Pinus radiata Organic Eprints
Hohmann, Pierre; Jones, E. Eirian; Hill, Robert A.; Stewart, Alison.
The plant health- and growth-promoting biological inoculant (bio-inoculant) Trichoderma hamatum LU592 was transformed with the constitutively expressed green fluorescent protein (gfp) and hygromycin B resistance (hph) genes to specifically monitor the isolate in the root system of Pinus radiata within a strong indigenous Trichoderma population. A modified dilution plating technique was developed to allow the determination of the mycelia proportion of total propagule levels. LU592 was shown to colonize the rhizosphere most effectively when 105 spores per pot were applied compared with inoculum concentrations of 103 and 107 spores per pot. LU592 extended its zone of activity beyond the rhizosphere to at least 1 cm away from the root surface. A positive...

Ecological studies of Trichoderma bio-inoculants in the soil ecosystem of Pinus radiata Organic Eprints
Hohmann, Pierre; Jones, E. Eirian; Hill, Robert A.; Stewart, Alison.
Three isolates of different Trichoderma species were selected for this study. T. hamatum (LU592) and T. harzianum (LU686), were known to stimulate growth and improve establishment of P. radiata seedlings, and T. atroviride (LU132) had no stimulatory activity. The ability of these isolates to establish and survive in bulk soil, the rhizosphere, rhizoplane or endorhizosphere of P. radiata seedlings was determined. In addition, the effect of each isolate on P. radiata seedling development and growth was assessed and is currently being confirmed in a large scale commercial experiment. From the nursery experiment, the Trichoderma isolate which was the most effective at colonising all P. radiata root subsystems (LU592) was selected for more detailed ecological...

Efficacy of copper alternatives applied as stop-sprays against Plasmopara viticola in grapevine Organic Eprints
Lukas, Kathrin; Innerebner, Gerd; Kelderer, Markus; Finckh, Maria R.; Hohmann, Pierre.
The six products, Armicarb, Vitisan, lime sulphur, Caso, Calce Fiocco and Ulmasud were tested for their ability to control downy mildew (Plasmopara viticola) on grapevine (Vitis vinifera) in order to find effective alternatives to copper, a heavy metal that is commonly used as a fungicide in organic viticulture. Each product was applied to potted grapevines at i) 40°h (degree hours) and ii) 80°h after inoculation (ai) of the pathogen. These so-called stop-sprays were tested on plants that received two different P. viticola inoculum rates. The formulated potassium bicarbonate product Armicarb and lime sulphur reduced disease incidence and severity similar to or better than the copper hydroxide treatment. Armicarb and lime sulphur reduced disease incidence...
