title: Insights into the recent emergence of powdery mildew on its 'new' host triticale: from origin to disease control.
abstract: The development of new crop species and their associated agro-ecosystems led simultaneously to the emergence of new pathogens (Stukenbrock and McDonald, 2008). This research focused on the recent emergence of powdery mildew (Blumeria graminis) on triticale (x Triticosecale Wittmack). In a first part, we aimed to gain insights into the evolutionary origin of this pathogen on its new host. A secondary aim was to investigate the presence of powdery mildew resistance in current commercial triticale cultivars, including its cellular basis of resistance. To address these research goals, we have pursued a molecular, pathological and cytological approach. This discussion will reflect on the experimental findings described in this research and their impact for future management of powdery mildew on triticale and other cereals.
