| Summary: | Powdery mildew is a common fungal disease of numerous ornamental plants (including dogwood, rose, phlox, and many bedding plants) that is commonly observed when atmospheric conditions provide warm days and cool nights. While powdery mildew does not always cause serious damage to an infected plant, it is capable of interfering with normal growth and reproduction. If the fungal infestation is severe enough, significant plant decline can be observed.
The subject invention provides plants with excellent resistance to powdery mildew. In a specific embodiment, the subject invention provides dogwood () cultivars that are resistant to infestation with powdery mildew. Specifically exemplified herein are culitvars identified as 'Jean's Appalachian Snow', 'Kay's Appalachian Mist', and 'Karen's Appalachian Blush'. The present invention also provides materials and methods for identifying, characterizing, and/or producing powdery mildew resistant plants. In a specific embodiment, the subject invention provides polynucleotide sequences, and patterns of polynucleotide sequences, which are associated with resistance to powdery mildew. These polynucleotides are characteristic of the powdery mildew resistant plants as described herein. Such polynucleotides are particularly useful in identifying and characterizing plant having resistance to powdery mildew. |
