Brem RB, Kruglyak L. "The landscape of genetic complexity across 5,700 gene expression traits in yeast." Proc Natl Acad Sci U S A. 2005 Feb 1;102(5):1572-7

Expression profiling of parental strains and 112 haploid progenies from a cross of strain BY4716 and the wild wine strain RM11-1a. Results used to find linkage between gene expression levels, which are treated as quantitative traits, and genetic markers.
