Novel strong promoter of antimicrobial peptides gene pro-SmAMP2 from chickweed (Stellaria media).
Article in BMC biotechnology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundIn a previous study we found that in chickweed the expression level of the pro-SmAMP2 gene was comparable or even higher to that of the β-actin gene. This high level of the gene expression has attracted our attention as an opportunity for the identification of novel strong promoters of plant origin, which could find its application in plant biotechnology. Therefore, in the present study we focused on the nucleotide sequence identification and the functional characteristics of the pro-SmAMP2 promoter in transgenic plants.
resultsIn chickweed (Stellaria media), a 2120 bp promoter region of the pro-SmAMP2 gene encoding antifungal peptides was sequenced. Six 5'-deletion variants -2120, -1504, -1149, -822, -455, and -290 bp of pro-SmAMP2 gene promoter were fused with the coding region of the reporter gene gusA in the plant expression vector pCambia1381Z. Independent transgenic plants of tobacco Nicotiana tabacum were obtained with each genetic structure. GUS protein activity assay in extracts from transgenic plants showed that all deletion variants of the promoter, except -290 bp, expressed the gusA gene. In most transgenic plants, the GUS activity level was comparable or higher than in plants with the viral promoter CaMV 35S. GUS activity remains high in progenies and its level correlates positively with the amount of gusA gene mRNA in T3 homozygous plants. The activity of the рro-SmAMP2 promoter was detected in all organs of the transgenic plants studied, during meiosis and in pollen as well.
conclusionOur results show that the рro-SmAMP2 promoter can be used for target genes expression control in transgenic plants.
