Pearson correlation coefficients calculated for comparisons of in-house with publicly available microarray dataIn (A) a list of commonly regulated genes (Supplementary Table S7 available at JXB online) and up-regulated genes in tpt-2, 48h after LL/HL transfer (Supplementary Table S8K* available at JXB online) have been used as basis for comparison. In (B) the gene lists for comparisons were obtained from Supplementary Tables S5A–C and S6A–C (available at JXB online).

The colums in (A) refer to threshold log2-fold change of ±1.5, whereas the columns in (B) are based on a threshold log2 ratio of ±1.0. Pearson correlation coefficients above/below 0.7/–0.7 are displayed in bold.

ND, not determined; none, less than three commonly regulated genes.

^a Less than four genes.
