DEA1, a circadian- and cold-regulated tomato gene, protects yeast cells from freezing death.
Article in Plant molecular biology, 2006. 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
Cold and freezing damage to plants can be mitigated by inducible factors during an acclimation period. DEA1 is a circadian-regulated tomato (Solanum lycopersicum) gene with sequence similarity to EARLI1, an Arabidopsis thaliana gene that confers cold protection. To investigate whether DEA1 was responsive to environmental variables such as cold, cold-treated tomatoes were analyzed for DEA1 expression. DEA1 transcript accumulated in response to cold, and the rapidity of the cold-induced transcript accumulation was regulated by the circadian rhythm. To test whether DEA1 could protect cells from freezing damage, we transformed the yeast, Pichia pastoris, with an inducible DEA1 construct. Yeast cells transformed with the gene survived freezing at a significantly higher rate than control strains and a strain expressing the LacZ gene. Transgenic tomato plants over-expressing or knocking down DEA1 transcript levels did not have an altered phenotype with respect to cold- or pathogen-susceptibility relative to control plants.
