CucCAP scientists identify gene for short-vining cucumber plants

The compact (cp) phenotype in cucumber is an important plant architecture-related trait with potential for breeding short-vining cucumber plants for high density planting and mechanized harvest. The Yiqun Weng group (USDA-ARS and the University of Wisconsin) conducted map-based cloning to identify the cp gene. Fine-mapping and functional characterization identified a gene on chromosome 4 encoding a receptor molecule that influences cell division in the stem apex. These findings provide new insights for the use of cp in cucumber breeding.
