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

A prototype 13-bp TATA-box sequence, TCACTATATATAG, was mutated at each nucleotide position and examined for its function in the core promoter. Specific nucleotides in the first TATA, the second TATA, as well as the flanking sequences influenced promoter function in transient transformation of tobacco (Nicotiana tabacum var Petit Havana) leaves. The effect of a given mutation on reporter gene expression in light versus dark was variable and sometimes contrasting. Some mutations, like T(7) or A(8)-->C or G, completely inactivated the expression of the minimal promoter in light but not in dark. In general, the sequence requirement for dark expression was less stringent than that for light expression. The selective effect of TATA-box mutations on light versus dark expression was exerted on core promoter function in the chromatin-integrated state also. Even in the presence of an upstream light response activator element, TATA-box mutations influenced modulation of the promoter by light. An A at the eighth position was specifically involved in the red light response of the promoter. Selectivity in gene expression was associated with a high level of transcript initiation from a site that was not active in the dark. Nuclear proteins from dark- and light-grown seedlings showed that the sequence variation within the TATA-box governs the formation of alternative transcriptional complexes. The experiments give direct evidence for the role of a core TATA-box sequence in determining the level as well as selectivity of gene expression in plants.
