“…Formate dehydrogenase (FDH) is a key enzyme involved in formaldehyde and formate metabolism in plants . Several lines of evidence showed that the transcription of FDH could be induced by formic acid, drought, hypoxia, and low temperature. − , Tobacco plants overexpressing Arabidopsis AtFDH enhanced the detoxification capability to formic acid and acetaldehyde. , Recently, a gene encoding formate dehydrogenase, VuFDH , has been identified from rice bean . However, differing from the subcellular localization of AAE3 and OCD proteins, VuFDH is localized to mitochondria.…”

Characterized by strong acidity, chelating ability, and reducing ability, oxalic acid, a low molecular weight dicarboxylic organic acid, plays important roles in the regulation of plant growth and development, the response to both biotic and abiotic stresses such as plant defense and heavy metals detoxification, and food quality. The metabolism of oxalic acid has been well-studied in microorganisms, fungi, and animals but remains less understood in plants. However, excessive accumulation of oxalic acid is detrimental to plants. Therefore, the level of oxalic acid has to be precisely controlled in plant tissues. In this review, we summarize the metabolism, function, and regulation of oxalic acid in plants, and we discuss solutions such as agricultural practices and plant biotechnology to manipulate oxalic acid metabolism to regulate plant responses to both external stimuli and internal developmental cues.

“…The fate of formaldehyde needs further investigation, but it is known that it can be emitted by plants or converted to non-toxic compounds ( Wang et al, 2016 ). Also, a recent study on trees has suggested that formaldehyde may represent an alternative carbon source for glycine methylation in photorespiration, and thus eliminating the need for a second glycine for the production of CH2-THF ( Jardine et al, 2017 ).…”

Serine metabolism in plants has been studied mostly in relation to photorespiration where serine is formed from two molecules of glycine. However, two other pathways of serine formation operate in plants and represent the branches of glycolysis diverging at the level of 3-phosphoglyceric acid. One branch (the glycerate – serine pathway) is initiated in the cytosol and involves glycerate formation from 3-phosphoglycerate, while the other (the phosphorylated serine pathway) operates in plastids and forms phosphohydroxypyruvate as an intermediate. Serine formed in these pathways becomes a precursor of glycine, formate and glycolate accumulating in stress conditions. The pathways can be linked to GABA shunt via transamination reactions and via participation of the same reductase for both glyoxylate and succinic semialdehyde. In this review paper we present a hypothesis of the regulation of redox balance in stressed plant cells via participation of the reactions associated with glycerate and phosphorylated serine pathways. We consider these pathways as important processes linking carbon and nitrogen metabolism and maintaining cellular redox and energy levels in stress conditions.

“…Notably, these FA concentrations fall well within the scope of physiological concentration, treating the condition of formaldehyde stress in plants, and are estimated to be 0.1–10 μmol g –1 in the fresh weight of a plant, 13 and up to 2–8 mM in the external treatment of HCHO stress. 14 , 15 , 37 …”

“…12 , 13 The primary sources of FA in plants are caused by the processes of methanol oxidation, dissociation of 5,10-methylene-THF, glyoxylate decarboxylation and other oxidative demethylation reactions. 14 Exogenous FA can also be absorbed and incorporated into the metabolism of plants. 7 , 15 , 16 As a result, phytoremediation has been extensively applied for the removal of FA from the polluted environment.…”

“… 7 , 15 , 16 As a result, phytoremediation has been extensively applied for the removal of FA from the polluted environment. However, the biological roles of FA and the mechanism of FA metabolism in plants have not yet been clearly defined, 14 and they are still challenging to study due to the lack of tools that can map the distribution of FA in live tissues. Thus, in order to understand the biological and pathological roles of FA well, it is crucial to develop sensitive methods or chemical tools for tracing and identifying FA in environmental samples and live plant tissues.…”
