Relationships exposed through gene expression profiling. Transcript changes (FC) of two different deletion mutants are plotted against each other. Red dots indicate the deleted genes. (A) Transcript changes of the pfk27Δ and tsl1Δ mutants are highly correlated. (B) Transcriptional changes of the asc1Δ mutant are not negatively correlated to those of the gpr1Δ mutant suggesting that Asc1 does not inhibit Gpr1. (C) The deletion of RAM1 results in many more transcriptional changes than the deletion of RAS2. RAS1 is not shown as its deletion behaves like WT.
