Fig. 2

Overrepresented GO terms of up-regulated (a) and down-regulated genes (b) under the tested conditions. DK, darkness; HL, high light; HT, high temperature. The size of an enriched GO term represents the number of differentially expressed genes (Log₂FC ≥ 1 and adjusted p value ≤ 1e−5) belonging to this GO term. Only GO terms with a p value ≤ 0.05 were used for semantic clustering using REVIGO [78]; redundant GO terms with a dispensability ratio ≥ 0.3 are not shown here but are available in Additional file 1: Table S3
