Fig. 2From: Transcriptional analysis of defense mechanisms in upland tetraploid switchgrass to greenbugsGenes differentially expressed in control and GB-infested (infested) plants associated with primary plant metabolism. Blue bars denote genes upregulated in control plants and orange bars denote genes upregulated in infested plants. In all cases, differential expression of genes is based on z-scores where cyan is low expression and magenta is high expression (a) Chlorophyll biosynthesis and degradation. b Photosynthesis. c Calvin Cycle. d Sucrose metabolism. e Starch metabolism. f Nitrogen metabolism.
