This genetic reprogramming by pathogens is a common feature of many infections. A famous example isagrobacterium, a bacterial infection that usually implants genes into host plants, which then produce extra amino acids unique to the bacterium. Biologists have piggy-backed on this trick in order to insert specific genes of interest, rather than virulence genes.
Pilar specifically wants to discern the patterns that arise. Is there a pattern between gene expression in response to a certain strain of the pathogen? What is the response of the wheat plant? How do different wheat varieties respond to infection?
Similarly, how do we discern what genes are expressed by wheat plants as a stress response, and what genes are differentially regulated by the wheat yellow rust pathogen?
