Modelling carbon assimilatory and recycling pathways in Arabidopsis seedlings

Seeds become primed for the process of germination following imbibition (taking up fluid). Unless environmental factors and genetic factors impede this process at a very early stage through dormancy, germination is a nonreversible process with the ultimate goal of producing a fully photosynthetic seedling. In order to support the growth of the newly germinated seedling, a seed’s lipid stores are mobilized and either converted into sugars for transport to sink tissues or respired for energy. Early research on the castor bean system demonstrated the involvement of the glyoxylate cycle to take acetyl-CoA from β-oxidation and convert it into organic acids for transport to the mitochondria, the switch-house between sugar formation and respiration.
