Global transcriptome changes in leaf 4 GZ by UV-B radiation analyzed using PageMan. A, Transcripts encoding proteins in primary and secondary metabolism. B, Transcripts encoding proteins in regulatory pathways. Transcripts that are down-regulated by UV-B are represented by blue boxes, while up-regulated transcripts are represented by red boxes. The color scale is shown in the top right corner. CHO, carbohydrate; TCA, tricarboxylic acid cycle; OPP, oxidative pentose phosphate pathway.
