KP4 to control Ustilago tritici in wheat: Enhanced greenhouse resistance to loose smut and changes in transcript abundance of pathogen related genes in infected KP4 plants.

Carolina Diaz Quijano, Fabienne Wichmann, Thomas Schlaich, Alessandro Fammartino, Jana Huckauf, Kerstin Schmidt, Christoph Unger, Inge Broer, Christof Sautter,

Ustilago tritici causes loose smut, which is a seed-borne fungal disease of wheat, and responsible for yield losses up to 40%. Loose smut is a threat to seed production in developing countries where small scale farmers use their own harvest as seed material. The killer protein 4 (KP4) is a ... Read more >>

Public funded field trials with transgenic plants in Europe: a comparison between Germany and Switzerland.

Henrik Nausch, Christof Sautter, Inge Broer, Kerstin Schmidt,

Field trails are indispensable for the scientific analysis of risks and potential benefits of genetically modified plants (GMP). The dramatic reduction of field trials in the European Union (EU) coincides with increasing safety demands, decreases in funding, and changes in the European directives. In parallel, opposition from non-governmental organizations (NGOs) ... Read more >>

The environment exerts a greater influence than the transgene on the transcriptome of field-grown wheat expressing the Pm3b allele.

Carolina Diaz Quijano, Susanne Brunner, Beat Keller, Wilhelm Gruissem, Christof Sautter,

Wheat provides 20 % of the calories consumed worldwide. Powdery mildew infections of wheat can result in more than 30 % yield loss but it has been demonstrated that wheat overexpressing Pm3b, an allele of the R gene Pm3, has enhanced resistance against powdery mildew under field conditions. A gene expression profile ... Read more >>

Surveying of pollen-mediated crop-to-crop gene flow from a wheat field trial as a biosafety measure.

Andrea Foetzki, Carolina Diaz Quijano, Odile Moullet, Alessandro Fammartino, Yvan Kneubuehler, Fabio Mascher, Christof Sautter, Franz Bigler,

Outcrosses from genetically modified (GM) to conventional crops by pollen-mediated gene flow (PMGF) are a concern when growing GM crops close to non-GM fields. This also applies to the experimental releases of GM plants in field trials. Therefore, biosafety measures such as isolation distances and surveying of PMGF are required ... Read more >>

Metabolomics and food processing: from semolina to pasta.

Romina Beleggia, Cristiano Platani, Roberto Papa, Annagrazia Di Chio, Eugenia Barros, Charlotte Mashaba, Judith Wirth, Alessandro Fammartino, Christof Sautter, Sean Conner, Johannes Rauscher, Derek Stewart, Luigi Cattivelli,

The objective of this study was to investigate the metabolite variations during industrial pasta processing (from semolina to dried pasta) for five different commercial products. Up to 76 metabolites were detected. Significant differences were observed between wholemeal and refined pasta samples, with the wholemeal pasta richer in many classes of ... Read more >>

Transgenic Pm3 multilines of wheat show increased powdery mildew resistance in the field.

Susanne Brunner, Daniel Stirnweis, Carolina Diaz Quijano, Gabriele Buesing, Gerhard Herren, Francis Parlange, Pierre Barret, Caroline Tassy, Christof Sautter, Michael Winzeler, Beat Keller,

Resistance (R) genes protect plants very effectively from disease, but many of them are rapidly overcome when present in widely grown cultivars. To overcome this lack of durability, strategies that increase host resistance diversity have been proposed. Among them is the use of multilines composed of near-isogenic lines (NILs) containing ...

Rice endosperm iron biofortification by targeted and synergistic action of nicotianamine synthase and ferritin.

Judith Wirth, Susanna Poletti, Beat Aeschlimann, Nandadeva Yakandawala, Benedikt Drosse, Sonia Osorio, Takayuki Tohge, Alisdair R Fernie, Detlef Günther, Wilhelm Gruissem, Christof Sautter,

Nearly one-third of the world's population, mostly women and children, suffer from iron malnutrition and its consequences, such as anaemia or impaired mental development. Iron fortification of food is difficult because soluble iron is either unstable or unpalatable, and non-soluble iron is not bioavailable. Genetic engineering of crop plants to ... Read more >>

Flavonoid profiling among wild type and related GM wheat varieties.

Jean-Robert Ioset, Bartosz Urbaniak, Karine Ndjoko-Ioset, Judith Wirth, Frédéric Martin, Wilhelm Gruissem, Kurt Hostettmann, Christof Sautter,

Pleiotropic effects are one of the main concerns regarding genetically modified organisms (GMOs). This includes unintended side effects of the transgene or its genome insertion site on the regulation of other endogenous genes, which could potentially cause the accumulation of different secondary metabolites that may have not only an impact ...

Exploration and Swiss field-testing of a viral gene for specific quantitative resistance against smuts and bunts in wheat.

Thomas Schlaich, Bartosz Urbaniak, Marie-Laure Plissonnier, Nicole Malgras, Christof Sautter,

The viral gene for the killer protein 4 (KP4) has been explored for its antifungal effect in genetically modified wheat to defeat specifically the seed-transmitted smut and bunt diseases. In vitro both important seed-transmitted diseases of wheat, loose smut (Ustilago tritici) and stinking smut (Tilletia caries), are susceptible to KP4, ... Read more >>

Increased field resistance to Tilletia caries provided by a specific antifungal virus gene in genetically engineered wheat.

Thomas Schlaich, Bartosz M Urbaniak, Nicole Malgras, Elisabeth Ehler, Christof Birrer, Lukas Meier, Christof Sautter,

The field performance of a viral gene in two Swiss wheat (Triticum aestivum) varieties showed 10% increased fungal resistance against Tilletia caries (stinking smut). To the best of our knowledge, this is the first report of improved resistance against any fungus in the field achieved by genetic engineering in wheat. ... Read more >>

Genetic engineering approaches to enrich rice with iron and vitamin A.

Lucca, Poletti, Sautter,

Major staple crops are often deficient in some of the nutrients required in human diet. Thus, malnutrition is a major problem, especially in developing countries, where a diversified diet is not affordable for the majority. Several strategies have been adopted to improve nutrition. However, micronutrient deficiency is still widely spread. ... Read more >>

Expression of the lipid transfer protein Ace-AMP1 in transgenic wheat enhances antifungal activity and defense responses.

Subhankar Roy-Barman, Christof Sautter, Bharat B Chattoo,

To enhance fungal disease resistance, wheat plants (cv. Bobwhite) were engineered to constitutively express the potent antimicrobial protein Ace-AMP1 from Allium cepa, driven by a maize ubiquitin promoter along with its first intron. The bar gene was used for selection of putative transformants on medium containing phosphinothricin (PPT). Transgene inheritance, ... Read more >>

Stable expression of a defense-related gene in wheat epidermis under transcriptional control of a novel promoter confers pathogen resistance.

Fredy Altpeter, Alok Varshney, Olaf Abderhalden, Dimitar Douchkov, Christof Sautter, Jochen Kumlehn, Robert Dudler, Patrick Schweizer,

Tissue-specific or regulated expression of transgenes is desirable in order to prevent pleiotropic side effects of putatively harmful transgene products as well as loss of energy resources due to unnecessary accumulation of transgene products. Epidermis-specific expression would be useful for many defense-related genes directed against attack by fungal pathogens that ... Read more >>

The nutritional fortification of cereals.

Susanna Poletti, Wilhelm Gruissem, Christof Sautter,

The low micronutrient content of cereals requires the fortification of food and biofortification of plants. Many laboratories are currently pursuing biofortification using breeding and genetic modification, but progress is challenged by technical hurdles and our understanding of physiological processes. Recent studies have largely been confined to the improvement of levels ... Read more >>
