2nd year engineering internship report

Plant qualitative (i.e. total) resistance to viruses is an efficient way of protecting crops, but it is often broken down by the emergence of adapted virus variants, able to infect those resistant plants. This evolutionary phenomenon can occur particularly quickly in monocultures deployed in vast areas. Different strategies have been studied,...

Plant qualitative resistances to viruses are natural exhaustible resources that can be impaired by the emergence of resistance-breaking (RB) virus variants. Mathematical modelling can help determine optimal strategies for resistance durability by a rational deployment of resistance in agroecosystems. Here, we propose an innovative approach,...

The deployment of pathogen-resistant crops often leads to the emergence of resistance-breaking pathogens that suppress the yield bene t provided by the resistance. In this work, we analyze if and how a modulation of the genetic drift experienced by the pathogens can slow this emergence down. For that purpose, we...
