Expression level of a flavonoid 3'-hydroxylase gene determines pathogen-induced color variation in sorghum.
Article in BMC research notes, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
backgroundSorghum (Sorghum bicolor L. Moench) accumulates 3-deoxyanthocyanidins and exhibits orange to purple coloration on parts of the leaf in response to infection with the fungus Bipolaris sorghicola. We aimed to identify the key genes determining this color variation.
resultsSorghum populations derived from Nakei-MS3B and M36001 accumulated apigeninidin, or both apigeninidin and luteolinidin, in different proportions in lesions caused by B. sorghicola infection, suggesting that the relative proportions of the two 3-deoxyanthocyanidins determine color variation. QTL analysis and genomic sequencing indicated that two closely linked loci on chromosome 4, containing the flavonoid 3'-hydroxylase (F3'H) and Tannin1 (Tan1) genes, were responsible for the lesion color variation. The F3'H locus in Nakei-MS3B had a genomic deletion resulting in the fusion of two tandemly arrayed F3'H genes. The recessive allele at the Tan1 locus derived from M36001 had a genomic insertion and encoded a non-functional WD40 repeat transcription factor. Whole-mRNA sequencing revealed that expression of the fused F3'H gene was conspicuously induced in purple sorghum lines. The levels of expression of F3'H matched the relative proportions of apigeninidin and luteolinidin.
conclusionsExpression of F3'H is responsible for the synthesis of luteolinidin; the expression level of this gene is therefore critical in determining color variation in sorghum leaves infected with B. sorghicola.
