  1. aThe list of potential candidate genes was compiled by searching TAIR (http://www.arabidopsis.org/) and Arabisopsis eFP Browser (http://bar.utoronto.ca/).
  2. bLoci known to be involved in coumarins biosynthesis.
  3. *Genes with the highest expression in roots of vegetative rosette.
  4. #Genes with relatively high expression in roots of vegetative rosette.
  5. The selected intervals are associated with scopolin (SCL1) and scopoletin (SCT4, SCT5) accumulation and are characterized by the highest percentage of phenotypic variance explained by each QTL and the highest LOD score values. Most of selected genes (except two highlighted with letter b) are novel loci.
