CucCAP scientists study effect of genome doubling on gene expression in tetraploid watermelon
Umesh Reddy and team at WVSU and Amnon Levi and team at USDA, ARS used advance genome sequencing technology to study the effect of genome doubling on gene expression in tetraploid watermelon versus their counterpart diploid watermelon parental plants.
CucCAP researchers identify QTL for resistance to Cucurbit yellow stunting disorder virus in melon
CucCAP scientists identify possible sources of resistance to bacterial fruit blotch in watermelon
Bacterial fruit blotch caused by Acidovorax citrulli is a serious disease of watermelon (Citrullus lanatus) in the U.S. Currently, there are no varieties resistant to the disease. In a 3-year study, 1452 accessions and cultivars were tested for resistance to fruit blotch at the immature fruit stage, where resistance is most important for growers.
CucCAP researches reveal Phytophthora capsici loci involved in mating type and mefenoxam sensitivity
In this study, researchers at Cornell collected 252 strains of the pathogen from across New York State and sequenced portions of their DNA in order to characterize the genetic structure of the pathogen population.
CucCAP researchers develop high-throughput method for quantification of pathogen growth
Researchers at Michigan State University used a fluorescent isolate of the broad host range pathogen, Phytophthora capsici, to develop a high-throughput, microtiter plate assay for replicated quantification of pathogen growth on plant tissue in real time. This method, which can detect pathogen growth prior to development of symptoms, can assist with screening for disease resistance, mapping of resistance loci, testing efficacy of control measures, or elucidation of fundamental host-pathogen interactions.
CucCAP scientists identify QTL for Phytophthora resistance in squash
CucCAP scientists from the Cornell University research groups of Michael Mazourek and Christine Smart along with Michael Gore’s lab combined linkage mapping and bulked segregant methods for molecular mapping and QTL identification.
CucCAP scientists test new squash breeding lines for performance and resistance to Phytophthora crown and root rot
Researchers at Cornell University developed squash breeding lines with increased resistance to Phytophthora crown and root rot.
