Expression of genes known to be involved in starch biosynthesis during tuber induction. A) Import of glucose 6-phosphate and ATP into the plastid and the conversion thereof to ADP-Glucose. GPT1 (light blue), GPT2 (dark blue), PGM (orange), NTT1 (brown), AGPase LS (light green), AGPase SS (dark green). B) Starch synthases and branching enzymes. SSII (dark grey), SSIII (light grey), GBSS (blue), SSIV (black), SBEA (light purple), SBEB (dark purple), ISA1 (dark red) and ISA2 (pink). C) Sucrose cleavage and phosphorylation. Cw-Inv (Black), FK (blue), Susy (gold), HK1 (Dark yellow) and HK2 (green). Values are the mean of two replicates.
