Functional analysis of the StERF79 gene in response to drought stress in potato (Solanum tuberosum L.).
Article in BMC plant biology, 2025. 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
backgroundThe AP2/ERF (APETALA 2/ethylene-responsive element binding factors) is a class of superfamily of plant-specific transcription factor that play an important regulatory role in many physiological and biochemical processes in plants.
resultsIn this study, overexpression of the StERF79 gene increased drought tolerance in potato plants, whereas StERF79 RNA interference expression (RNAi) lines decreased drought tolerance in potato plants. In addition, the superoxide dismutase (SOD), peroxide dismutase (POD), and catalase (CAT) activities, as well as proline (Pro) content of StERF79 transgenic lines, showed significantly higher results than those of the wild type (WT) potato plants under natural drought stress conditions, while the malondialdehyde (MDA) content was lower. The StERF79 transcription factor can respond to drought stress by interacting with a DRE cis-acting element in the promoter region of the downstream target gene (StDHN-2), and activating its expression, the result was validated by using yeast one hybrid (Y1H), Dual-Luciferase and β-glucuronidase (GUS) staining assays both in vivo and in vitro. The StDHN-2 gene is a member of the dehydrin (DHN) subfamily of the potato plant late embryonic developmentally abundant (LEA) protein family. LEA, hydrophilic proteins found in plants, serve as cellular dewatering protectants to prevent desiccation during various stresses.
conclusionThe results could provide novel knowledge into the functional analysis of the StERF79 gene in positive regulation of the StDHN-2 gene to drought response and its possible mechanisms in potato plants. CLINICAL TRIAL NUMBER: Not applicable.
