Fructose-bisphosphate aldolase that plays a key role in glycolysis and gluconeogenesis (By similarity). Involved in gibberellin-mediated root growth. May be regulated by CDPK13. Associates with vacuolar proton ATPase (V-ATPase) and may regulate the V-ATPase-mediated control of root cell elongation (PubMed:15821984). beta-D-fructose 1,6-bisphosphate = D-glyceraldehyde 3-phosphate + dihydroxyacetone phosphate Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 4/4. Homotetramer. Expressed in callus. By gravity stress (PubMed:1363521). Induced by gibberellin (PubMed:15821984). Plants silencing FBA1 display reduced root length. Belongs to the class I fructose-bisphosphate aldolase family. Wrong choice of frame. Sequencing errors. Wrong choice of frame. Sequencing errors.
