Figure 2

Temporal pattern of gene expression for selected starch metabolic proteins. The set of genes whose co-expression across the entire set of NASC microarray data is correlated with that of At5g39790 was obtained as detailed in Methods. Eight genes that encode plastid-localized starch metabolic proteins were noted where the Pearson correlation coefficient for co-expression exceeded r = 0.50. Diurnal gene expression data was then obtained from the NASC website as detailed in Methods, and placed into Microsoft Excel. Data were expressed as relative expression vs mean, using data from replicate experiments. Correlation coefficients were calculated comparing expression patterns of At5g39790 to each of the eight other genes, and the mean of this set of correlation coefficients is presented in the Figure. The individual correlation coefficients are as follows: At5g64860 (DPE1) 0.5937; At3g29320 (PHS1) 0.7696; At1g70820 (PGM2) 0.9231; At1g03310 (ISA2) 0.8061; At1g69830 (AMY3) 0.6890; At2g39930 (ISA1) 0.8534; At4g18240 (STS4) 0.5564; At1g10760 (GWD1) 0.6499. The first twelve hour period is the dark period, the second twelve hour period is the light period.
