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 uncover the genetic basis of unique horticultural traits in the multi-disease resistant cucumber germplasm line WI2757

CucCAP researchers conducted molecular mapping using populations involving WI2757, and uncovered a large paracentric inversion of about 10 megabases in length on cucumber chromosome 1 of WI2757 and found that inversion region harbors genes or quantitative trait loci for fruit length, diameter, fruit shape, fruit number, and flowering time.

CucCAP scientists provide inventory of genes and QTL for cucumber breeding and genetics community

CucCAP scientists and collaborators provide an extensive review of the literature to systematically document genes for simply inherited traits, QTL for 130 quantitative traits, and develop recommendations for QTL nomenclature in cucumber. In a separate study, researchers conducted comparative analysis on the genetic basis of fruit size and shape variation among cucumber, melon and watermelon, and revealed both conserved and unique genetic architecture of fruit size/shape variation among cucurbit crops.
