Induced ectopic expression of At-CBF1 in marker-free transgenic tomatoes confers enhanced chilling tolerance.

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
In an attempt to improve chilling stress tolerance, an Arabidopsis C-repeat binding factor 1 (At-CBF1) gene driven by the inducible promoter RD29A was co-transferred into tomato var. Shalimar. Marker (NPTII)-free transgenic were obtained in T(1) generation because of unlinked integration of CBF1 and NPTII genes. Reverse transcription-polymerase chain reaction confirmed the expression of CBF1 in T(1) transgenic lines. Study of expression pattern in T(1) transgenic line showed a gradual increase with increasing chilling stress period and also confirmed the reversibility of expression on removal of stress. The transgenic plants exhibited no morphological and agronomical differences as compared to non-transformed plants. When young transgenic plants were exposed to chilling stress (4°C) for 3 days, increased survival (50%) was observed in transgenic lines than non-transformed plants (10%). Transgenic plants subjected to the chilling stress showed a significant decrease in membrane injury index and lipid peroxidation and also increased significantly free proline content in the leaf tissues as compared to non-transformed plants. Thus, these findings indicate that marker-free transgenic tomato plants expressing Arabidopsis CBF1 gene provided protection and conferred cold tolerance to transgenic tomato without any phenotypic variation.
