CucCAP researchers genetically characterize more than 2000 melon accessions in the U.S. National Plant Germplasm System

The U.S. National Plant Germplasm System maintains a melon germplasm collection from worldwide melon production areas and regions where primitive melons exist. The CucCAP team genetically characterized the collection to increase understanding of genetic diversity, phylogenetic relationships, and population structure of the collection, and to improve melon taxonomic classifications. A core collection was developed from the analysis to provide a public resource for future research and genomics-assisted breeding. Thirty-five morphological characters were evaluated in the core collection to identify genomic regions potentially related to fruit quality and other horticultural traits important in melon improvement.

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.
