Title

Natures balancing act: examining biosynthesis de novo, recycling and processing damaged vitamin B metabolites

Abstract Plants use B vitamin compounds as cofactors for metabolism. Biosynthesis de novo of these metabolites in plants is almost fully elucidated. However, salvaging of precursors as well as cofactor derivatives is only being unraveled. Furthermore, processing of these compounds when damaged by cellular activities to prevent deleterious effects on metabolism is emerging. Recent investigations indicate that the role of B vitamins goes beyond metabolism and are being linked with epigenetic traits, specific developmental cues, the circadian clock, as well as abiotic and biotic stress responses. More in depth investigations on the regulation of the provision of these compounds through biosynthesis de novo, salvage and transport is suggesting that plants may share the cost of this load by division of labor.
