SlMYB2: an R2R3-MYB transcription factor enhancing drought, salt, and cadmium tolerance in Solanum lycopersicum.
Article in Plant cell reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
key messageSolanum lycopersicum SlMYB2 enhances drought, salt, and cadmium stress tolerance by upregulating stress-responsive genes, improving proline levels and antioxidant activity, and reducing oxidative damage. MYB transcription factors are widely present in plants and play critical roles in regulating responses to abiotic stresses, yet most remain poorly characterized. In this study, a typical R2R3-MYB gene (SlMYB2) from Solanum lycopersicum was isolated and identified, and its role in abiotic stress response was investigated. Stress-related cis-acting elements were present in the promoter sequence of SlMYB2, such as drought response elements, low-temperature response elements, and ABA response elements. Subcellular localization analysis showed that SlMYB2 is localized in the nucleus. Transactivation activity assay in yeast cells revealed that SlMYB2 has transactivation activity, and its active domain is located in the C-terminal. Drought, salt, and cadmium stress resulted in a rapid induction of SlMYB2 expression in tomato. Furthermore, compared to wild-type plants, SlMYB2-overexpressing Arabidopsis thaliana showed a higher seed germination rate and cotyledon greening rate, along with significantly increased proline content, chlorophyll levels, and peroxidase activity under drought, salt, and cadmium stress. In contrast, the transgenic lines exhibited a significantly lower malondialdehyde content than the wild-type. Expression analysis demonstrated that SlMYB2 overexpression upregulated key drought-, salt-, and cadmium-responsive genes under stress conditions, supporting its central role in the transcriptional regulation of integrated multi-stress tolerance in plants. These results indicated that SlMYB2 acts as a positive regulator in enhancing plant tolerance to drought, salt, and cadmium stress.
