CucCAP Researchers Provide High Resolution Genetic Characterization of the U.S. Cucumber Germplasm Collection

Germplasm collections (a.k.a. gene banks) are a crucial resource to conserve natural genetic diversity and provide a source of novel traits for crop improvement such as disease and pest resistance, increased yield, and improved fruit quality. Optimal collection, preservation and utilization of these resources depends upon knowledge of the genetic variation present within the collection. […]

Karyotype Stability and Unbiased Fractionation in the Paleo-Allotetraploid Cucurbita Genomes: Molecular Plant

Analyses of high-quality genome sequences of Cucurbita maxima and C. moschata revealan ancient allotetraploidy event in Cucurbita. The two subgenomes of paleo-allotetraploidCucurbita show limited interchromosomal rearrangements, and display no genome dominanceand biased fractionation. Allele-specific expression analysis in the hybrid of C.maxima × C. moschata detects transgressive expression correlated with heterosis inimportant agronomic traits. Source: Karyotype […]
