The Thiamine Biosynthesis Gene THI1 Promotes Nodule Growth and Seed Maturation.
Article in Plant physiology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Thiamine (vitamin B1) is essential for living organisms. Unlike animals, plants can synthesize thiamine. In Lotus japonicus, the expression of two thiamine biosynthesis genes, THI1 and THIC, was enhanced by inoculation with rhizobia but not by inoculation with arbuscular mycorrhizal fungi. THIC and THI2 (a THI1 paralog) were expressed in uninoculated leaves. THI2-knockdown plants and the transposon insertion mutant thiC had chlorotic leaves. This typical phenotype of thiamine deficiency was rescued by an exogenous supply of thiamine. In wild-type plants, THI1 was expressed mainly in roots and nodules, and the thi1 mutant had green leaves even in the absence of exogenous thiamine. THI1 was highly expressed in actively dividing cells of nodule primordia. The thi1 mutant had small nodules, and this phenotype was rescued by exogenous thiamine and by THI1 complementation. Exogenous thiamine increased nodule diameter, but the level of arbuscular mycorrhizal colonization was unaffected in the thi1 mutant or by exogenous thiamine. Expression of symbiotic marker genes was induced normally, implying that mainly nodule growth was delayed in the thi1 mutant. Furthermore, this mutant formed many immature seeds with reduced seed weight. These results indicate that thiamine biosynthesis mediated by THI1 enhances nodule enlargement and is required for seed development in L. japonicus.
