Eucarpia Edito Small grain cereals are the most widely grown annual crops worldwide. Wheat and barley are the two major cereals with cultivated surfaces of 230 and 60 Mha, respectively. Cereal grains have a huge range of utilization and wheat represents ~19% of human calorie intake, up to 50% in some countries. It is processed in many different products (breads, biscuits, breakfast, beer…). It is also widely used for ruminant and monogastric feed, and by biofuel (ethanol) or biomaterial industry. Cereal production dramatically increased after the green revolution (1960-1990), but the production rate is now decreasing (see http://www.wheatinitiative.org/about-wheat/factsheets-infographics). The reason is a slight decrease of the surface cultivated with cereals because of competition with other crops or non-agricultural uses. Another reason is a slower yield progression, partially attributed to climate change. To face the challenge of food security for an ever-growing world population, cereal yield must be pushed upward, but not at any cost. Indeed, intensive production systems using fertilizers and pesticides are increasingly questioned for their negative impacts on the environment or human health. For example, nitrates in fresh or marine water cause eutrophication and pesticide residues may have carcinogenic effect or act as endocrine disruptors. Consumers and citizen are also more and more demanding for sustainable farming systems and safe products. Plant breeding is often presented as a sustainable way to produce more and better. Recent developments in genomics, genotyping, phenotyping and breeding methodologies open new perspectives to design future varieties, with higher performance or resilience, targeting more specific conditions and utilizations, and more environmentally friendly. The cereal section congress of EUCARPIA (www.eucarpia.org) is the opportunity to learn about recent developments in genetics and cereal breeding, from basic research on quantitative genetics, breeding methodology, crop modelling, genome organization and evolution to applied research on genome editing, QTL detection for marker assisted selection, plant-micro-organism interaction, biotic and abiotic stresses. The 2nd edition of the International Wheat Innovation Workshop (IWIW2) is the opportunity to present complementary results obtained in major wheat programmes and pave the way for future collaborations and funding opportunities. Gilles CHARMET February 25th, 2018, Clermont-Ferrand, France Head of the Eucarpia Organizing Committee i IWIW Edito In recent years, many scientific and technological advances have opened up huge opportunities to select more efficiently for complex traits and accelerate the pace of genetic progress. These include the long-awaited availability of the wheat genome reference sequence and its annotation, the development of genomic selection and high throughput phenotyping methods, and the fine-tuning of increasingly precise and specific genome editing techniques... How can we use these fantastic opportunities to meet the challenge of global change? The issue is now to define optimal strategies to combine all these results and tools, all the multidisciplinary skills and all the academic, private and institutional partners to breed for better adapted cereals cultivars. We designed this day of exchange and reflexion to help generate these strategies. The second edition of the International Wheat Innovation Workshop (IWIW2) is indeed the opportunity to exchange on topics of interest with the wheat community and pave the way for future collaborations and funding opportunities. It is built around topics which have known major evolutions recently and will probably continue change rapidly: Genetic resources, Phenotyping, Genome editing, Genomic selection and Bio-informatics. This workshop is organized at the initiative of the BreedWheat project, and associates some of the major wheat programmes: Design Future Wheat program (UK BBSRC), proWeizen (German research and breeding alliance) and CRP Wheat (CGIAR challenge program) as well as the Wheat Initiative. We thank in advance the speakers that accepted to describe the state of the art and speculate about the future in introductory and impulse talks that will feed the group sessions. We hope that this day and the World Café will be fruitful to all and lead to new networks of collaborations and relevant projects.

Abstract: In host-pathogen interactions RNA interference (RNAi) has emerged as a pivotal mecha- nism to modify both, the immune responses of the host as well as the pathogenicity and virulence of the pathogen. In addition, in some fungi RNAi is also known to affect chromosome biology via its effect on chromatin conformation. Previous studies reported no effect of the RNAi machinery on the virulence of the fungal plant pathogen Zymoseptoria tritici however the role of RNAi is still poorly understood in this species. Herein, we elucidate whether the RNAi machinery is conserved within the genus Zymoseptoria. Moreover, we conduct functional analyses of Argonaute and Dicer-like proteins and test if the RNAi machinery affects chromosome stability. We show that the RNAi machinery is conserved among closely related Zymoseptoria species while an exceptional pattern of allelic diversity was possibly caused by introgression.

  • Zymoseptoria Tritici-Wheat: the Metabolic Interface of a Crop Pathogen and Its Host Plant
    Zymoseptoria tritici-wheat: the metabolic interface of a crop pathogen and its host plant Supervisory team: Main supervisor: Dr Helen Fones (Eyles) (University of Exeter) Second supervisor: Prof Nick Smirnoff (University of Exeter) Prof David Studholme (University of Exeter) Collaborators: Dr Gary Barker (University of Bristol) Host institution: University of Exeter (Streatham) Project description: Zymoseptoria tritici, the causal agent of Septoria Triciti Blotch (STB), is Europe’s most important pathogen of wheat, costing the UK economy alone around £300M per annum in lost yields and spending on fungicides. There is a great need to better understand how this fungus interacts with the wheat plant and with other microbes on the leaf surface, in order to find new ways to control STB: at present, we are reliant on fungicides to which the fungus is beginning to develop resistance. One area in which little is currently known is how the fungus obtains nutrients in early infection. Work in the Fones’ lab has recently shown that this fungus can remain on the leaf surface (epiphytic) for at least ten days before entering and infecting the leaf, and that it does not simply survive there but grows and even reproduces. Currently, we do not know how the fungus obtains nutrients during this phase. Zymoseptoria tritici isolates differ in the duration and extent of this surface growth and reproduction. In this PhD project, you will sample an array of Zymoseptoria tritici isolates from the field and use microscopy, molecular biology and plant pathology to determine their epiphytic growth phenotypes. You will carry out a Genome-Wide Association Study (GWAS) to identify the genetic differences which underpin variation in surface growth characteristics, with a particular interest in genes involved in nutrient acquisition and usage.

  • Zymoseptoria Tritici Isolates

Crous; syn. Mycosphaerella graminicola, Septoria tritici), causal agent of Septoria tritici blotch (STB) disease, is one of the most important foliar diseases of wheat in Iran and across the world. To identify resistance sources than can be relevant to breeding programs, it is necessary to determine the virulence factors of the pathogen. In this study, 26 differential wheat cultivars (carrying Stb1–18 genes) were inoculated as seedlings in a greenhouse with 10 individual isolates of Z. tritici collected from different regions of Iran under different environmental conditions. Iranian Z. tritici isolates showed new virulence patterns. Among wheat differentials, none of the cultivars were resistant to all the Iranian isolates used in this study. Oasis (carrying Stb1), Sulivan (carrying Stb2), and Bulgaria 88 (carrying Stb1 and Stb6) showed susceptibility to all the isolates. Stb5, Stb7, Stb13, and Stb14 possibly do not have a good resistance as most of the isolates were virulent to these genes. Therefore, these genes cannot be considered as effective sources of resistance to Z. tritici. Shafir (carrying Stb6) revealed a resistant reaction to most of the isolates. M3 (carrying Stb16 and Stb17) was susceptible to four Z. tritici isolates, and this is the first report of susceptibility reaction for this cultivar.

  • Early Molecular Signatures of Responses of Wheat to Zymoseptoria Tritici in Compatible and Incompatible Interactions
    Plant Pathology (2016) Doi: 10.1111/ppa.12633 Early molecular signatures of responses of wheat to Zymoseptoria tritici in compatible and incompatible interactions E. S. Ortona, J. J.Ruddb and J. K. M. Browna* aJohn Innes Centre, Norwich Research Park, Norwich NR4 7UH; and bRothamsted Research, Harpenden AL5 2JQ, UK Zymoseptoria tritici, the causal agent of septoria tritici blotch, a serious foliar disease of wheat, is a necrotrophic pathogen that undergoes a long latent period. Emergence of insensitivity to fungicides, and pesticide reduction policies, mean there is a pressing need to understand septoria and control it through greater varietal resistance. Stb6 and Stb15, the most common qualitative resistance genes in modern wheat cultivars, determine specific resistance to avirulent fun- gal genotypes following a gene-for-gene relationship. This study investigated compatible and incompatible interactions of wheat with Z. tritici using eight combinations of cultivars and isolates, with the aim of identifying molecular responses that could be used as markers for disease resistance during the early, symptomless phase of colonization. The accumulation of TaMPK3 was estimated using western blotting, and the expression of genes implicated in gene-for- gene interactions of plants with a wide range of other pathogens was measured by qRT-PCR during the presymp- tomatic stages of infection. Production of TaMPK3 and expression of most of the genes responded to inoculation with Z. tritici but varied considerably between experimental replicates. However, there was no significant difference between compatible and incompatible interactions in any of the responses tested. These results demonstrate that the molecular biology of the gene-for-gene interaction between wheat and Zymoseptoria is unlike that in many other plant diseases, indicate that environmental conditions may strongly influence early responses of wheat to infection by Z.

I certify that all material in this thesis which is not my own work has been identified and that no material has previously been submitted and approved for the award of a degree by this or any other University. Signature: (William Kay) 1 Thesis Abstract Zymoseptoria tritici, the causal agent of Septoria tritici blotch (STB), is the most economically important pathogen of wheat in temperate climates. EU spending on the control of STB is estimated at more than € 1.3 billion per annum, even when tolerant cultivars are used. This thesis comprises 5 data chapters each looking to ascertain reasons for the success of Z. tritici. Using mainly in vitro methods combined with confocal microscopy, this thesis explores asexual spore submergence in rain, epiphytic development, the potential triggers for pycnidiation, low-nutrient ex planta survival, and soil treatments as a novel method of control. Novel findings include that (i) submergence leads to a form of spore dormancy, (ii) epiphytic development is more extensive than previously thought with hyphal growth and sporulation both occurring readily over a 21 day period, (iii) pycnidiation is a rapid, deterministic developmental process, triggered by contents of lysed plant cells, (iv) asexual spores have the capacity to survive for many weeks in low-nutrient environments, and finally (v) that treating soil-borne environmental spores may be a novel way to reduce field inoculum levels before a new crop is sown.

Abstract: Phytopathogenic Ascomycota are responsible for substantial economic losses each year, destroying valuable crops. The present study aims to provide new insights into phytopathogenicity in Ascomycota from a comparative genomic perspective. This has been achieved by categorizing orthologous gene groups (orthogroups) from 68 phytopathogenic and 24 non-phytopathogenic Ascomycota genomes into three classes: Core, (pathogen or non-pathogen) group-specific, and genome-specific accessory orthogroups. We found that (i) ~20% orthogroups are group-specific and accessory in the 92 Ascomycota genomes, (ii) phytopathogenicity is not phylogenetically determined, (iii) group-specific orthogroups have more enriched functional terms than accessory orthogroups and this trend is particularly evident in phytopathogenic fungi, (iv) secreted proteins with signal peptides and horizontal gene transfers (HGTs) are the two functional terms that show the highest Citation: Peterson, D.; Li, T.; Calvo, occurrence and significance in group-specific orthogroups, (v) a number of other functional terms are A.M.; Yin, Y.
