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

The potential of using vector-free minimal gene cassettes (MGCs) with a double terminator for the enhancement and stabilization of transgene expression was tested in sugarcane biolistic transformation. The MGC system used consisted of the enhanced yellow fluorescent protein (EYFP) reporter gene driven by the maize ubiquitin-1 (Ubi) promoter and a single or double terminator from nopaline synthase (Tnos) or/and Cauliflower mosaic virus 35S (35ST). Transient EYFP expression from Tnos or 35ST single terminator MGC was very low and unstable, typically peaking early (8-16 h) and diminishing rapidly (48-72 h) after bombardment. Addition of a ~260 bp vector sequence (VS) to the single MGC downstream of Tnos (Tnos + VS) or 35ST (35ST + VS) enhanced EYFP expression by 1.25- to 25-fold. However, a much more significant increase in EYFP expression was achieved when the VS in 35ST + VS was replaced by Tnos to generate a 35ST-Tnos double terminator MGC, reaching its maximum at 24 h post-bombardment. The enhanced EYFP expression from the double terminator MGC was maintained for a long period of time (168 h), resulting in an overall increase of 5- to 65-fold and 10- to 160-fold as compared to the 35ST and Tnos single terminator MGCs, respectively. The efficiency of the double terminator MGC in enhancing EYFP expression was also demonstrated in sorghum and tobacco, suggesting that the underlying mechanism is highly conserved among monocots and dicots. Our results also suggest the involvement of posttranscriptional gene silencing in the reduced and unstable transgene expression from single terminator MGCs in plants.
