The role of gibberellin synthase gene VvGA2ox7 acts as a positive regulator to salt stress in Arabidopsis thaliana.
Article in BMC plant biology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
backgroundSoil salinity is an important environmental component affecting plant growth and yield, but high-salinity soils are a major constraint to the development of the grape industry. Previous studies have provided lines of evidence that gibberellins (GAs) play a significant regulatory role in plant responses to salt stress. However, it remains unclear whether GA2ox, a key enzyme that maintains the balance of bioactive gibberellins and intermediates in plants, is involved in the mechanism of salt stress tolerance in grapes.
resultsIn this study, we found that GA2ox7 positively modulates salt stress via its ectopic expression in Arabidopsis thaliana. The GA2ox7 gene cloned from grape was a hydrophilic protein, its CDS length was 1002 bp. Besides, VvGA2ox7 protein contained DIOX_N and 2OG-FeII_Oxy domains and was localized at the nucleus and cytoplasm. Yeast two-hybrid (Y2H) showed VvARCN1, VvB5R, VvRUB2, and VvCAR11 might be potential interaction proteins of VvGA2ox7. Compared with the wild type, overexpression of VvGA2ox7 in Arabidopsis thaliana enhanced antioxidant enzymatic activities and proline, chlorophyll, and ABA contents, and decreased relative electrical conductivity, malondialdehyde, and GA
conclusionsTaken together, this investigation indicates that VvGA2ox7 may act as a positive regulator in response to salt stress and provide novel insights for a deeper understanding of the role of VvGA2ox7 in grapes.
