Many sources of resistance to diseases such as powdery mildew, downy mildew, Phytophthora rot, and aphid and whitefly transmitted viruses have been identified in related Cucurbita species. Geoffrey Meru and colleagues at University of Florida review the use of genomic tools to identify genetic loci conferring resistance to facilitate more efficient deployment of these materials for breeding.

The CucCAP website features recently published articles from the four crop teams, (Cucumber, Melon, Squash, and Watermelon) and the Bioinformatics, Breeding, & Genomics group. Integtated crop and disease management activities, articles and reports are also featured.
CucCAP scientists collaborate to develop diagnostic guide for fusarium rot of pumpkin and winter squash
Fusarium rot is an important soil-borne disease impacting production and storage of pumpkins and winter squash. A new guide has been published to facilitate diagnosis of this disease by outlining taxonomy, symptoms, isolation, and epidemiology of the disease, and providing morphologic and PCR-based methods to identify the pathogen.
CucCAP scientists study basis for resistance to squash vein yellowing virus resistance in watermelon
Watermelon production in the southeastern U.S. is subject to severe crop losses due to several viruses, including squash vein yellowing virus (SqVYV). Gene expression analysis of a resistant breeding line by the Kousik group at the U.S. Vegetable Laboratory Charleston SC, indicated potential involvement of a variety of defensive responses. These findings can assist further functional studies and the development of SqVYV-resistant watermelon cultivars.
CucCAP scientist documents emergence of new melon and watermelon virus in southwestern U.S.
Researchers studied the new mosaic symptomology and foliar distortion of new growth observed in Arizona and California on melon and watermelon.
