A maize QTL for silk maysin levels contains duplicated Myb-homologous genes which jointly regulate flavone biosynthesis.
Article in Plant molecular biology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 26 papers, 1 of them a synthesis that pooled it.
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
The maize p1 locus coincides with a major QTL (quantitative trait locus) determining levels of maysin, a C-glycosyl flavone that deters feeding by corn ear-worm. The p1 gene is tightly linked with a second gene, p2, and both genes encode similar Myb-domain proteins. We show here that maize cell cultures transformed with either the p1 or p2 genes expressed under a constitutive promoter accumulate transcripts for flavonoid biosynthetic genes, and synthesize phenylpropanoids and C-glycosyl flavones related to maysin. Additionally, maize plants that are deleted for the p1 gene have reduced maysin levels and moderate silk-browning reaction, whereas plants with a deletion of both p1 and p2 have non-detectable silk maysin and non-browning silks. We conclude that both p1 and p2 induce maysin biosynthesis in silk, although the two genes differ in their expression and pigmentation effects in other tissues. These results show that a QTL for flavone biosynthesis actually comprises two tightly linked genes with related functions.
