Abundance of transcripts encoding enzymes involved in glucose metabolism. Red arrows indicate reactions that were more pronounced in EXP7 cells; the weight of the arrows is proportional to the difference between EXP7 and non-GFP protoplasts expressed in ΔRPKM. Green symbols denote enzymes for which significantly enriched transcripts have been detected. GFP, green fluorescent protein; Glu6P, glucose-6-phosphate; ME, malic enzyme; OAA, oxaloacetate; PCK1, phosphoenolpyruvate carboxykinase; PEP, phosphoenolpyruvate; RPKM, reads per 1 Kbps of exon model per million mapped reads.
