PL1 fusion gene: a novel visual selectable marker gene that confers tolerance to multiple abiotic stresses in transgenic tomato.
Article in Transgenic research, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Visual selectable markers, including the purple color caused by the accumulation of anthocyanins, have been proposed for use as antibiotic-free alternatives. However, the excessive accumulation of anthocyanins seriously inhibits the growth and development of transgenic plants. In our study, the AtDWF4 promoter from Arabidopsis and the tomato LeANT1 gene, encoding a MYB transcription factor, were used to construct the PL1 fusion gene to test whether it could be used as a visual selectable marker gene for tomato transformation. All the PL1 transgenic shoots exhibited intense purple color on shoot induction medium. In the transgenic tomato plants, PL1 was highly expressed in the cotyledons, but expressed only slightly in the true leaves and other organs. The expression of PL1 had no significantly adverse effects on the growth or development of the transgenic tomato plants, and conferred tolerance to multiple abiotic stresses in them. With the “cut off green shoots” method, multiple independent 35S::GFP transgenic tomato lines were successfully obtained using PL1 as the selectable marker gene. These results suggest that PL1 has potential application of visual selectable marker gene for tomato transformation.
