Figure 1

Principle of vector analysis. (A) The change in expression of a gene in the two experimental backgrounds is represented by a vector. The two axes correspond to the log-fold changes in the two backgrounds. E.g., Gene 1 is strongly up-regulated in both backgrounds, while Gene 2 is specifically down-regulated in background A, but has lost this response in background B. (B) The plane can be systematically subdivided into sectors corresponding to the main behavior types that are possible. In the centre, genes show very little response in either background (white). Other genes respond about the same in both backgrounds (blue sector), are specifically changed in only one background (yellow), or are regulated in opposite directions in background A and B (red).
