Host-pathogen interaction is characterized by rapid evolutionary adaptation, particularly in man-made environments. It was discovered that resistance in plants follow Mendel"s laws, opening the door for homogeneous resistant variants. Such resistance has in many cases proved short-lived because it has triggered a selection benefiting virulence in the pathogen. There are, however great variations in host/pathogen systems. Incomplete resistance or the use of heterogenity can be more stable, but is the farmer or the consumer ready to accept this? How can we control the resistance in natural resources in a sustainable manner? The course will use review articles and on-line resources to draw the line from Mendel to molecular genetics and genetic modification.
The students shall understand the evolutionary genetics of host-pathogen interactions and involves an understanding of the genetics of both host and pathogens.Sustainable use of resistance genes in plants as part of IPM strategies. Inoculation and disease-assessment techniques, analysis of resistance in plant populations. To understand how plant protection strategies based on resistance can be made stable and sustainable.
