GUS expression in Arabidopsis directed by 5' regions of the pea metallothionein-like gene PsMTA.
Article in Plant molecular biology, 1997. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Upstream sequences (including the first seven codons) of a metallothionein (MT)-like gene from pea, PsMTA, were fused to GUS and introduced into Arabidopsis. High-level GUS expression was detected in the roots of plants grown on MS medium, except in regions proximal to the root apex. There was precise delineation of the root-shoot boundary. In soil-grown plants there was low GUS expression and this was absent from the more mature regions of the roots. In the aerial tissues of soil-grown plants, GUS expression was restricted to hydathodes, stipules, expanding cotyledons and the following senescent tissues: leaves, cotyledons, petals, sepals, filaments, stigmas, nectaries and siliques. A 298 bp region was shown to be required for GUS expression in roots but not for expression in vegetative aerial tissues of plants grown on MS medium. This region contains predicted ethylene-responsive elements (EREs) but similar patterns of GUS expression were detected in etr1 seedlings. GUS expression was significantly higher in roots exposed to 500 nM copper, but this increase was small in proportion to expression in roots exposed to 50 nM copper.
