FDR <0.05 for all genes shown. Positive fold changes for genes up-regulated in sucrose compared with mannitol, negative fold changes indicate down regulation in sucrose compared with mannitol. Signal intensity is the normalized log2 signal intensity for each gene in the mannitol treatment (calls present in at least one treatment, sucrose or mannitol). The average normalized log 2 signal intensity on the arrays (calls present) was 7.2.
