Figure 3From: Differential SAGE analysis in Arabidopsis uncovers increased transcriptome complexity in response to low temperatureGenes clustered according to expression profiles. Genes exhibiting a transient increase in expression after (A) 30 minutes and (B) 2 hours of low temperature treatment. C) Genes mimicking COR gene expression, which are positively correlated with an increase in freezing tolerance. The red line represents the desired profile and black lines indicate the expression pattern of genes assigned to that profile, highlighting the variation observed for each profile.Back to article page
