Abstract

Carbon fixation is one of the most fundamental aspects of plant physiology. It is carried out by RuBisCO (ribulose bisphosphate
carboxylase), an enzyme that also catalyzes oxygenation reaction yielding 'toxic' intermediates. At optimal conditions, RuBisCO
preferentially incorporates inorganic carbon into organic carbon skeletons (RuBP, ribulose-1,5-bis phosphate), generating two
molecules of 3-phosphoglycerate. This simple compound is subsequently used to build other organic molecules of life and contributes
significantly to plant growth and increased biomass. Thus, RuBisCO is a potential target for genetic manipulation to improve plant
yield by strengthening source-sink relationship.
