Fig. 3.

Identified ginseng genes associated with Gene Ontology (GO)-terms, “response to high light intensity,” “response to reactive oxygen species (ROS),” or both and their expression profile under high light and recovery conditions. The color key indicates that color intensity represents the degree of log2-fold changes in gene expression in each pairwise comparison. (A) Upregulated genes in HT vs. CH and their expression profile in each pairwise comparison. Genes with bold red and bold black color were identified to be associated with “response to high light intensity” and “response to ROS,” respectively. Genes in grey box were involved in both GO-terms. (B) Downregulated genes in HT vs. CH identified to be associated with “response to high light intensity” and their expression profiles in each pairwise comparison.

HT, high light–treated sample; CH, corresponding control for HT; RT; recovery-treated sample after HL treatment; CR, corresponding control for RT.
