Figure 5: Gene ontology-enriched categories for biological processes among transcripts induced or repressed by cold (4 °C).

(a) Processes enriched for cold-induced transcripts. (b) Processes enriched for cold-repressed transcripts. The induced or repressed DEGs were annotated to the GO database using a hypergeometric test. The calculated P value underwent a Bonferroni correction and the threshold of the corrected P value was less than 0.05.
