Figure 3

Time course profile of gene categories (GOSlim-plant terms). Hierarchical clustering analysis was performed to monitor the time-course profiles of gene categories basing on the fold changes relative to 0 d. The arrows indicate the gene categories that were initially induced after short term vernalization and activated after long-term vernalization.
