This image was selected as our holiday card for 2009. It is a portion of AraNet, a gene association network built from over 50 million data points of functional genomics data from the experimental mustard plant Arabidopsis. Each line represents a functional link between two genes and the color indicates the strength of the link using a red-blue heat map scheme. It was submitted by Sue Rhee, Insuk Lee and Michael Ahn from the Department of Plant Biology.
