A 42 bp fragment of the pmas1' promoter containing an ocs-like element confers a developmental, wound- and chemically inducible expression pattern.

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
Synthesis of mannopine in plant tissues infected with Agrobacterium tumefaciens is controlled by a divergent promoter (pmas2' and pmas1') that in 479 bp contains all the cis-acting elements necessary to direct tissue-specific and wound-inducible expression. In this report, using transgenic tobacco plants harboring a pmas1'-beta-glucuronidase (GUS) gene fusion, we investigated the developmental expression pattern directed by pmas1' in the early stages of development and the responses of pmas1' to different chemical inducers. It was found that this promoter can respond to auxins, cytokinins, methyl jasmonate (MJ), salicylic acid (SA) and its analogue 2,6-dichloroisonicotinic acid (iNA). Treatment with chemical inducers also showed that the effects of iNA are organ-dependent, that wound-induction is a complex response mediated by at least two different chemical signals, and that MJ stimulates changes in the tissue-specific and developmental expression pattern directed by the ptmas1' promoter. Using chimeric promoters we demonstrate that an ocs-like element (ocs+1) directs MJ responses in an orientation-dependent manner and that sequences around the ocs+1 are important to maintain the inducible and developmental properties of this cis-regulatory element.
