The course is of 4 ECTS and is organised by Mogens Støvring Hovmøller, Professor, Aarhus University - Science and Technology.
This is the second course in the NOVA PhD course series "Plant Pathology with a Nordic Dimension", which is scheduled for 2017-2020. The series consist of four courses, each within different disciplines in plant pathology. The course in 2018 has the following topic:
Biotrophy in Plant Pathogens - from Recognition to Ecology
Focus is on plant interactions with biotrophic pathogens aiming at understanding plant defence reactions, pathogen effector biology and the ecology of biotrophic plant pathogens.
The course to be given in 2018 has a focus on interactions between the host plant and biotrophic pathogens aiming at understanding pathogen effector biology, defence responses of the host plant, how the plant accommodate and feed the pathogen, and the ecology of biotrophs in natural and/or agricultural cropping systems. Effector biology has become an important theme for biotrophic and other pathogens due to large-scale identification of effector candidates through genome- and transcriptome sequencing. At the course, we will give an overview of how effectors play their roles, how they interact with targets in the plant, how they evolve and how they can be studied in different pathosystems. Biotrophic interactions will be studied from early recognition through defence signalling to execution of various defence reactions at both genetic, molecular and cellular levels. We will discuss the zig-zag model and how it impacts on biotrophy, resistance based on single R-genes as well as non-host resistance. This is important in relation to pathogen populations and how new virulent pathogen strains may evolve. Phenotypic host responses at both microscopic and macroscopic levels will be considered, including how biotrophic fungi interact with resistant and susceptible host plants. The utilization of R-genes in practical plant breeding and in evaluation of disease resistance in official variety testing will be demonstrated. The ecology of biotrophic rust fungi in natural and agricultural cropping systems will be examined by studying the role and prevalence of the primary hosts year round, and by the particular role of alternate (sexual) hosts in cereal rust epidemiology.
Each course in the course series includes definitions, terms, concepts and theories within the plant pathology disciplines reflected in the course title. Two main themes will be the core of each course schedule. Cases with special relevance for the Nordic zone will have highest priority. Understanding plant pathogen interactions and biocontrol at the molecular level will be prioritised embracing genomics, transcriptome and gene expression studies. Importance of cell wall degrading enzymes, effector molecules and secondary metabolites will be addressed. Discussions of biocontrol, epidemiology, population dynamics and plant resistance as part of integrated pest management will be part of each course.
