Abstract Thiamine diphosphate (vitamin B(1)) plays a fundamental role as an enzymatic
cofactor in universal metabolic pathways including glycolysis, the pentose
phosphate pathway, and the tricarboxylic acid cycle. In addition, thiamine
diphosphate has recently been shown to have functions other than as a cofactor
in response to abiotic and biotic stress in plants. Recently, several steps of
the plant thiamine biosynthetic pathway have been characterized, and a mechanism
of feedback regulation of thiamine biosynthesis via riboswitch has been
unraveled. This review focuses on these most recent advances made in our
understanding of thiamine metabolism and functions in plants. Phenotypes of
plant mutants affected in thiamine biosynthesis are described, and genomics,
proteomics, and metabolomics data that have increased further our knowledge of
plant thiamine metabolic pathways and functions are summarized. Aspects of
thiamine metabolism such as catabolism, salvage, and transport in plants are
discussed.
