Schematic representation of regulated genes involved in carbohydrate metabolism. A model of starch and sucrose metabolism is represented. The model shows genes (AGI numbers) revealing an altered expression profile in cfbp1 rosettes and roots; and cyfbp rosettes and roots. Rosette regulated genes (upper panel) are numbered as follows: glyceraldehyde 3-phosphate dehydrogenase (At1g79530), cFBP1 (At3g54050), ADP-glucose pyrophosphorylase large subunit 4 (At2g21590), beta-amylase 4 (At5g55700), alpha-isoamylase 3 (At4g09020), four sugar transporter family proteins B amylase 5 and 6 (At2g32290 and At4g15210), pyruvate kinase (At5g08570), pyrophosphate-fructose-6-phosphate 1-phosphotransferase (At1g12000), pfkB-like carbohydrate kinase (At1g06030), trehalose-phosphatase synthase 2 (At1g16980), trehalose-6-phosphate phosphatase (At1g35910). Root regulated genes (lower panel) are: ribulose bisphosphate carboxylase small chain (At1g67090), rubisco activase (At2g39730), Rubisco small subunit (At5g38430), phosphoglycerate kinase (At3g12780), Glyceraldehyde-3-phosphate dehydrogenase B (At1g42970), fructose-bisphosphate aldolase (At4g38970), cFBP1 (At3g54050), carbohydrate transmembrane transporter (At1g08930), pyruvate kinase (At5g63680), 2,3-bisphosphoglycerate mutase (At3g08590), glyceraldehyde-3-phosphate dehydrogenase (At3g04120), xilulose kinase 2 (At5g49650), cyFBP (At1g43670), phosphofructokinases PFK2 (At5g47810) and PFK7 (At5g56630); glucose-6-phosphate isomerase (At5g42740), inositol-3-phosphate synthase (At5g10170), inositol-3-phosphate synthase (At2g22240). (+) indicates up-regulated, and (-) indicates down-regulated. Pink circles indicate genes which are supposed to be located in plastid or plasma membranes, according to Cell eFP Browser prediction for subcellular localization (http://bar.utoronto.ca/cell_efp/cgi-bin/cell_efp.cgi). (*) predicted as plasma membrane and/or Golgi apparatus transporters; (†) three putative localizations: plasma membrane, Golgi apparatus, and plastid
