Origins and metabolism of formate in higher plants

Formate, a simple one-carbon compound, is readily metabolized in plant tissues. In greening potato tubers, similar to some procaryotes, formate is directly synthesized via a ferredoxin-dependent fixation of CO2, serving as the main precursor for carbon skeletons in biosynthetic pathways. In other pl...

Description
Summary:Formate, a simple one-carbon compound, is readily metabolized in plant tissues. In greening potato tubers, similar to some procaryotes, formate is directly synthesized via a ferredoxin-dependent fixation of CO2, serving as the main precursor for carbon skeletons in biosynthetic pathways. In other plant species and tissues, formate appears as a side-product of photorespiration and of fermentation pathways, but possibly also as a product of direct CO2 reduction in chloroplasts. Formate metabolism is closely related to serine synthesis and to all subsequent reactions originating from serine. Formate may have a role in biosynthesis of numerous compounds, in energetic metabolism and in signal transduction pathways related to stress response. This review summarizes the current state of formate research, physiological/biochemical and molecular aspects.
