An overview of cold responsive genes annotated in MapMan functional groups for primary and secondary metabolism. Comparison of (A)T. salsuginea and (B)Arabidopsis genes encoding proteins involved in primary and secondary metabolisms. Samples derived from T. salsuginea Yukon were hybridized against T. salsuginea arrays, samples derived from Arabidopsis Col-0 to Arabidopsis arrays. Differential gene expression was determined in response to 14 days of cold acclimation at 4°C. Significance of expression changes was determined with a threshold of p < 0.05 after false discovery correction by fitting the data to a linear model. Blue indicates significantly up-regulated and red significantly down-regulated genes. Note the large difference in the number of regulated genes in the light reactions bin between the two species.
