Genetic analysis of developmentally regulated resistance to downy mildew (Hyaloperonospora parasitica) in Arabidopsis thaliana.
Although developmentally regulated disease resistance has been observed in a variety of plant-pathogen interactions, the molecular basis of this phenomenon is not well understood. Arabidopsis thaliana ecotype Columbia-0 (Col-0) expresses a developmentally regulated resistance to Hyaloperonospora parasitica isolate Emco5. Col-0 seedlings support profuse mycelial growth and asexual spore formatio...
متن کاملIdentification of arabidopsis loci required for susceptibility to the downy mildew pathogen Hyaloperonospora parasitica.
Plants are susceptible to a limited number of pathogens. Most infections fail due to active defense or absence of compatibility. Many components of the plant's surveillance system and defense arsenal have been identified in the last decades. However, knowledge is limited on compatibility; in particular, the role of plant factors in the infection process. To gain insight into these processes, we...
متن کاملUltrastructure of the host–pathogen interface in Arabidopsis thaliana leaves infected by the downy mildew Hyaloperonospora parasitica
Transmission electron microscopy was used to examine the host–pathogen interface in Arabidopsis thaliana (L.) Heynh. leaves infected by the biotrophic downy mildew pathogen Hyaloperonospora parasitica (Pers.:Fr.) Constant. Both conventionally fixed as well as high-pressure frozen samples were examined. Excellent preservation of the host–pathogen interface was obtained in many of our high-pressu...
متن کاملDecay of Genes Encoding the Oomycete Flagellar Proteome in the Downy Mildew Hyaloperonospora arabidopsidis
Zoospores are central to the life cycles of most of the eukaryotic microbes known as oomycetes, but some genera have lost the ability to form these flagellated cells. In the plant pathogen Phytophthora infestans, genes encoding 257 proteins associated with flagella were identified by comparative genomics. These included the main structural components of the axoneme and basal body, proteins invo...
متن کاملEvaluation of fungicides for the control of downy mildew (Peronospora parasitica) in canola
Downy mildew, caused by Peronospora parasitica Pers. ex Fr., is an important disease of canola that has implications during early seedling establishment. The fungus invades young seedlings and severe infection results in premature defoliation. In worst cases, the systemic infection may even kill the seedlings. Current commercial varieties of canola are very susceptible to downy mildew. Therefor...
