  • Title: Race nonspecific resistance for potato late blight.
    Author: Staples RC.
    Journal: Trends Plant Sci; 2004 Jan; 9(1):5-6. PubMed ID: 14729211.
    Abstract:
    The late blight fungus (Phytophthora infestans) rots susceptible species of potato plants. None of the major varieties of potato (Solanum tuberosum) grown in the USA is resistant to US-8, the most prevalent genotype of the fungus. Now, Junqi Song, James Bradeen and colleagues have cloned the RB gene from the wild diploid potato species, Solanum bulbocastanum, using a map-based approach in combination with long-range PCR. Transgenic plants containing the gene, normally fully susceptible, displayed broad-spectrum late blight resistance.
