abstract：:Quantitative trait loci (QTL) have been discovered in crops, where some of causal quantitative trait genes (QTGs) may not be functionally characterized even in model plant Arabidopsis. We propose an approach to delineate QTGs by coordinating expression of genes located within QTL in crops and known orthologs related w...
