Thiamine 22-29 thiaminC Arabidopsis thaliana 111-129 31911438-8 2020 Using bimolecular fluorescence complementation and in vitro Fe-S cluster transfer experiments, we confirmed interactions with two proteins involved in isoprenoid and thiamine biosynthesis, 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate synthase (ISPG) and 4-amino-5-hydroxymethyl-2-methylpyrimidine phosphate synthase (THIC), respectively. Thiamine 166-174 thiaminC Arabidopsis thaliana 319-323 26454882-11 2015 Resulting THI1 x THIC plants accumulated up to 3.4- and 2.6-fold more total thiamin than wild-type plants in leaf and seeds, respectively. Thiamine 76-83 thiaminC Arabidopsis thaliana 17-21 23341335-4 2013 Our results show that thiamin biosynthesis is largely regulated by the circadian clock via the activity of the THIAMIN C SYNTHASE (THIC) promoter, while the riboswitch located at the 3" untranslated region of this gene controls overall thiamin biosynthesis. Thiamine 22-29 thiaminC Arabidopsis thaliana 131-135 23341335-6 2013 Our model suggests that in Arabidopsis, the THIC promoter and the thiamin-pyrophosphate riboswitch act simultaneously to tightly regulate thiamin biosynthesis in a circadian manner and consequently sense and control vital points of core cellular metabolism. Thiamine 66-73 thiaminC Arabidopsis thaliana 44-48 18533652-2 2008 In plants, TPP regulates its own production by binding to the 3" untranslated region of the mRNA encoding ThiC, a critical enzyme in thiamine biosynthesis, which promotes the formation of an unstable splicing variant. Thiamine 133-141 thiaminC Arabidopsis thaliana 106-110 19812694-11 2009 Two classical genetic markers (PY, ALB1) were identified based on similar map locations of known genes required for thiamine (THIC) and chlorophyll (PDE166) biosynthesis. Thiamine 116-124 thiaminC Arabidopsis thaliana 126-130 18332905-0 2008 AtTHIC, a gene involved in thiamine biosynthesis in Arabidopsis thaliana. Thiamine 27-35 thiaminC Arabidopsis thaliana 0-6 18332905-4 2008 Here we report the molecular characterization of AtTHIC, which is involved in thiamine biosynthesis in Arabidopsis. Thiamine 78-86 thiaminC Arabidopsis thaliana 49-55 18332905-7 2008 Downregulation of AtTHIC expression by T-DNA insertion at its promoter region resulted in a drastic reduction of thiamine content in plants and the knock-down mutant thic1 showed albino (white leaves) and lethal phenotypes under the normal culture conditions. Thiamine 113-121 thiaminC Arabidopsis thaliana 18-24 18332905-10 2008 AtTHIC was strongly expressed in leaves, flowers and siliques and the transcription of AtTHIC was downregulated by extrinsic thiamine. Thiamine 125-133 thiaminC Arabidopsis thaliana 0-6 18332905-10 2008 AtTHIC was strongly expressed in leaves, flowers and siliques and the transcription of AtTHIC was downregulated by extrinsic thiamine. Thiamine 125-133 thiaminC Arabidopsis thaliana 87-93 18332905-11 2008 In conclusion, AtTHIC is a gene involved in pyrimidine synthesis in the thiamine biosynthesis pathway of Arabidopsis, and our results provide some new clues for elucidating the pathway of thiamine biosynthesis in plants. Thiamine 72-80 thiaminC Arabidopsis thaliana 15-21 18332905-11 2008 In conclusion, AtTHIC is a gene involved in pyrimidine synthesis in the thiamine biosynthesis pathway of Arabidopsis, and our results provide some new clues for elucidating the pathway of thiamine biosynthesis in plants. Thiamine 188-196 thiaminC Arabidopsis thaliana 15-21 18048325-6 2007 Here, we identify a homolog of THIC in Arabidopsis and demonstrate its essentiality not only for vitamin B1 biosynthesis, but also plant viability. Thiamine 97-107 thiaminC Arabidopsis thaliana 31-35 18048325-0 2007 Vitamin B1 biosynthesis in plants requires the essential iron sulfur cluster protein, THIC. Thiamine 0-10 thiaminC Arabidopsis thaliana 86-90 18048325-9 2007 The results suggest that vitamin B1 biosynthesis in plants is in fact more similar to prokaryotic counterparts and that the THIC protein is likely to be the key regulatory protein in the pathway.
