Project description:Tetraploid emmer Triticum turgidum subsp. dicoccum is one of the first wheat species to be domesticated. Emmer shares many pathogen species with modern durum wheat (Triticum turgidum subsp. durum) and hexaploid bread wheat (Triticum aestivum L.). Domesticated emmer is considered a highly valuable source of potentially novel disease resistance genes that can be introduced into modern wheat varieties, however, large gaps remain in our understanding of the basic immune responses of emmer to the most common wheat pathogens. In this work we describe the transcriptional response of emmer to single and mixed pathogen species infections with the ascomycete Zymoseptoria tritici, and the basidiomycete Puccinia graminis. In doing so, we here uncover unique patterns in the response of emmer to a more complex pathogen population with mixed species infections.

Project description:Wheat is one of the most significant crops in terms of human consumption in the world. In a climate change scenario, extreme weather event such as heatwaves will be more frequent especially during the grain-filling (GF) stage and could affect grain weight and quality of crops. Molecular mechanisms underlying the response to short heat stress (HS) have been widely reported for the hexaploid wheat (Triticum aestivum) but the regulatory heat stress mechanisms in tetraploid durum wheat (Triticum turgidum ssp. durum) remain partially understood. In this work, we performed a transcriptomic analysis of durum wheat grains to HS during early GF to identify key HS response genes and their predicted regulatory networks under glasshouse conditions.
