Abstract #301174

This is the preliminary program for the 2004 Joint Statistical Meetings in Toronto, Canada. Currently included in this program is the "technical" program, schedule of invited, topic contributed, regular contributed and poster sessions; Continuing Education courses (August 7-10, 2004); and Committee and Business Meetings. This on-line program will be updated frequently to reflect the most current revisions.

Title:	QTL-mapping of Gene Expression Levels of a Eucalyptus Backcross

Keywords:	QTL mapping ; quantitative trait ; gene expression
Abstract:	Quantitative trait loci (QTL)-mapping finds genomic regions associated with a quantitative trait such as wood density in trees or hypertension in humans. Gene expression levels within an organism are highly correlated and can also be treated as quantitative traits. My research consists of summarizing thousands of gene expressions levels into fewer components and then finding putative gene regulatory regions associated with them. The data used in this research consists of 2,610 gene expression levels and 18 phenotypic traits measured in 88 trees from a backcross of two eucalyptus strains: eucalyptus grandis and eucalyptus globulus.
