1 · What the graph read from 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.

2 · The registry

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

By screening for new seed color mutations, we have identified a new gene, pale aleurone color1 (pac1), which when mutated causes a reduction in anthocyanin pigmentation. The pac1 gene is not allelic to any known anthocyanin biosynthetic or regulatory gene. The pac1-ref allele is recessive, nonlethal, and only reduces pigment in kernels, not in vegetative tissues. Genetic and molecular evidence shows that the pac1-ref allele reduces pigmentation by reducing RNA levels of the biosynthetic genes in the pathway. The mutant does not reduce the RNA levels of either of the two regulatory genes, b and c1. Introduction of an anthocyanin structural gene promoter (a1) driving a reporter gene into maize aleurones shows that pac1-ref kernels have reduced expression resulting from the action of the a1 promoter. Introduction of the reporter gene with constructs that express the regulatory genes b and c1 or the phlobaphene pathway regulator p shows that this reduction in a1-driven expression occurs in both the presence and absence of these regulators. Our results imply that pac1 is required for either b/c1 or p activation of anthocyanin biosynthetic gene expression and that pac1 acts independently of these regulatory genes.
