decreased PFPase activity in rice perturbs the equilibration of carbon metabolism during grain filling but has no visible phenotypic effects during the vegetative and reproductive growth stages
Prevotella copri is able to grow in minimal media containing xylose or hemicelluloses as the sole carbon source. The organism converts C5-sugars via the sedoheptulose-1,7-bisphosphate pathway (SBPP) to connect pentose metabolism with glycolysis. To circumvent the transaldolase reaction, Prevotella copri uses the combined catalysis of a pyrophosphate-dependent phosphofructokinase and a fructose-bisphosphate aldolase

expression of PFP inhibits triose phosphate to hexose phosphate recycling, and concomitantly increases hexose phosphate pools in the immature internodes
the seedling growth of the subunits Pfpalpha1/alpha2 and Pfpbeta1/beta2 double mutants and the Pfpalpha1/alpha2/beta1/beta2 quadruple mutant is severely retarded under salt and osmotic stress conditions compared with that of the wild type. In contrast, the vegetative growth of the wild type and Pfp mutants after the seedling stage is similarly affected by salt and osmotic stresses
transgenic tobacco plants overexpressing the alpha-subunit do not show visible phenotype changes, while plants overexpressing the beta-subunit grow faster at the cost of reduced leaf size and sucrose content. Fructose content increases in growing plants compared with wild-type plants
two phosphofructokinase and two diphosphate-fructose-6-phosphate-phosphotransferase transcripts accumulate during anoxic stress, whereas mRNA levels of four phosphofructokinase and three diphosphate-fructose-6-phosphate-phosphotransferase genes are decreased. The total specific activity of both phosphofructokinase and diphosphate-fructose-6-phosphate-phosphotransferase changes only slightly during a 24-h anoxia treatment. Expression of different isoforms and their catalytic properties may differ during normoxic and anoxic conditions and contribute to balanced glycolytic activity during the low-oxygen stress
the enzyme regulates carbon metabolism during grain filling in rice. The catalytic subunit PFPbeta has a pivotal role in the accumulation of starch in the endosperm
