DOI: 10.1042/bsr20180048
Abstract: In plants, the hydroxymethylpyrimidine (HMP) and thiazole precursors of thiamin are synthesized and coupled together to form thiamin in plastids. Mutants unable to form HMP can be rescued by exogenous HMP, implying the presence of… read more here.

DOI: 10.1080/01904167.2018.1549670
Abstract: Abstract Boron (B) toxicity is an important environmental constraint that limits crop productivity. Salicylic acid (SA) and thiamin participate in the processes underlying plant adaptations to certain types of abiotic and biotic stress. This study… read more here.

DOI: 10.1111/jipb.13283
Abstract: Vitamin B1 (VB1), including thiamin, thiamin monophosphate (TMP), and thiamin pyrophosphate (TPP), is an essential micronutrient for all living organisms. Nevertheless, the precise function of VB1 in rice remains unclear. Here, we described a VB1… read more here.

DOI: 10.1111/pbi.13545
Abstract: Summary Rice is a major food crop to approximately half of the human population. Unfortunately, the starchy endosperm, which is the remaining portion of the seed after polishing, contains limited amounts of micronutrients. Here, it… read more here.

DOI: 10.1128/jb.00503-21
Abstract: Vitamin B1 (thiamin) is an essential nutrient for cellular metabolism. Microorganisms that are unable to synthesize thiamin either fully or in part exogenously obtain it from their environment or via exchanges with other microbial members… read more here.
