2007 journal article

Regulation of the Arabidopsis thaliana vitamin B-6 biosynthesis genes by abiotic stress

PLANT PHYSIOLOGY AND BIOCHEMISTRY, 45(2), 152–161.

By: S. Densiow, E. Rueschhoff n & M. Daub n

author keywords: antioxidant; plant abiotic stress; SNZ1; SNO; YaaD; YaaE
MeSH headings : Antioxidants / metabolism; Arabidopsis / metabolism; Arabidopsis Proteins / metabolism; Arabidopsis Proteins / physiology; Carbon-Nitrogen Lyases; Escherichia coli / metabolism; Gene Expression Regulation, Plant; Genes, Plant; Green Fluorescent Proteins / metabolism; Microscopy, Fluorescence; Nitrogenous Group Transferases / metabolism; Nitrogenous Group Transferases / physiology; Oxidative Stress; Phylogeny; Plant Proteins / metabolism; RNA, Messenger / metabolism; Time Factors; Vitamin B 6 / metabolism
TL;DR: All three PDX1 genes and PDX2 were responsive to abiotic stressors including high light, chilling, drought, and ozone, however, the response ofPDX1.2 was disparate from that of the other PDX genes, showing a lessened response to high light , chilling, and drought, but an increased response to ozone.

2005 journal article

Regulation of biosynthetic genes and antioxidant properties of vitamin B-6 vitamers during plant defense responses

PHYSIOLOGICAL AND MOLECULAR PLANT PATHOLOGY, 66(6), 244–255.

By: S. Denslow n, A. Walls n & M. Daub n

author keywords: vitamin B-6; pyridoxine; antioxidant; plant defense; PDX1; PDX2; SOR1; SNO; SNZ; Nicotiana tabacum cv. 'Burley 21'; Pseudomonas syringae pv. phaseolicola; Pseudomonas syringae pv. tabaci
TL;DR: Findings indicate that during plant defense responses, vitamin B6 functions and its synthesis is regulated in a manner consistent with this vitamin’s activity as an antioxidant and modulator of active oxygen species in vivo. (via Semantic Scholar)

2004 journal article

Functional complementation between the PDX1 vitamin B-6 biosynthetic gene of Cercospora nicotianae and pdxJ of Escherichia coli

FEBS LETTERS, 564(1-2), 143–146.

By: D. Wetzel n, M. Ehrenshaft n, S. Denslow n & M. Daub n

author keywords: SNZ; YaaD; SOR1; PYROA; pyridoxal-5 '-phosphate; pyridoxamine
MeSH headings : Ascomycota / genetics; Cloning, Molecular; Enzymes / physiology; Escherichia coli Proteins / genetics; Escherichia coli Proteins / physiology; Fungal Proteins / genetics; Fungal Proteins / physiology; Genes, Fungal; Genetic Complementation Test; Ligases / genetics; Ligases / physiology; Oxidoreductases; Pyridoxine / biosynthesis; Transformation, Genetic; Vitamin B 6 / biosynthesis
TL;DR: The PDX1 gene of the alternative B6 pathway encodes a protein responsible for synthesis of the pyridoxine ring, which is likely to be responsible for de novo vitamin B6 biosynthesis in Escherichia coli. (via Semantic Scholar)
