Document Content and Description Below
Plant-Pathogen Interactions (Ch. 13) April 26Why study plant-pathogen interactions? Science 327:804 (2010)Three main strategies to utilize the host plant as a substrate: 1. Necrotrophic: plant ti ... ssue killed and then colonized by the pathogen, e.g. gray mold fungus. 2. Biotrophic: Plant cells remain alive throughout the infection. Viruses are obligate biotrophs. 3. Hemibiotrophic: Plant cells alive only in the initial stages of the infection. Plant pathogens include: Virus, bacteria, fungi, oomycetes, and nematodesPathogens can switch from biotrophic to necrotrophic mode due to increasing nutritional demands as the biomass increases The oomycete, Phytophthora infestans, which causes potato late blight disease was responsible for the disease epidemic in Ireland (1846-1847) and the Irish potato famine and the exit of more than 106 people from Ireland.How do pathogens get into plants?
