The CucCAP Bioinformatics team is led by BTI plant genomics scientist Zhangjun Fei. Team members include Shan Wu who is working to integrate the watermelon pan genome and Jingyin Yu who is redesigning the data base.
We identified QTLs associated with gummy stem blight resistance in an interspecific F2:3 Citrullus population and developed marker assays for selection of the loci in watermelon.

Multiple disease screens of the USDA watermelon germplasm collection have highlighted the value of wild type watermelons as a source for enhancing resistance to diseases in modern watermelon cultivars. CucCAP researchers collaborated with Sakata Seed America on generating genetic populations and on conducting genetic analyses to identify genetic loci that confer resistance to Fusarium wilt and papaya ring-spot virus.
Watermelon has been domesticated for more than 4000 years and modern sweet watermelons have been selected to carry large fruits with crisp, non-bitter and sweet flesh. The CucCAP team has co-led an international effort to generate an improved watermelon ‘97103’ reference genome and resequence 414 accessions from the seven extant Citrullus species.
SNPS from GBS data of Cucurbita accessions, including C. pepo, C. maxima and C. moschata are made publicly available prior to publication under a data release policy.
Years of selection for desirable fruit quality traits in dessert watermelon (Citrullus lanatus) has resulted in a narrow genetic base in modern cultivars. Development of novel genomic and genetic resources offers great potential to expand genetic diversity and improve important traits in watermelon. The CucCAP team has developed a high‐quality genome sequence for the principal […]
