Fig 8. Conserved expression of glucose 6-phosphate transporter 2 (GPT2) across CAM plants and regulation of starch metabolism in S. album.

(A) Maximum likelihood phylogeny of GPT1 and GPT2 among 10 species. (B) Transcript expression of GPT2 in C3 timecourses (Arabidopsis and well-watered S. album), CAM-cycling (drought induced S. album) and constitutive CAM (pineapple and K. fedtschenkoi) is plotted. (C) Schematic diagram representing the regulation of starch synthesis, cytosolic PGI bypass, cytosolic and plastidic G6P shunt in S. album under CAM-cycling photosynthesis. Abbreviations are as follows: GAP: glyceraldehyde 3-phosphate; DHAP: dihydroxyacetone phosphate; F6P: fructose 6-phosphate; G6P: glucose 6-phosphate; FBP: fructose 1,6-bisphosphate; Ru5P: ribulose 5-phosphate; TPT: triose phosphate/phosphate translocator; GPT2: glucose 6-phosphate/phosphate translocator 2.
