Phylogeny-based comparative analysis of gene expression modulation upon drought stress across three cotton diploids.
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 5 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
backgroundDrought stress is a significant global challenge that negatively impacts cotton fiber yield and quality. Although many drought-stress responsive genes have been identified in cotton species (Gossypium spp.), the diversity of drought response mechanisms across cotton species remains largely unexplored. This study compared gene expression modulation in response to drought stress across three diploid cotton species: G. arboreum, G. stocksii, and G. bickii.
resultsWe observed significant variation in the content and biological roles of differentially expressed genes among the studied species, along with enhanced divergence in ortholog expression patterns under drought stress. These findings suggest a remodeling of drought response mechanisms during the independent evolution of cotton species. Additionally, we identified 287 genes exhibiting similar regulatory responses to drought across species, highlighting pathways including starch and sucrose metabolism, chlorophyll catabolite degradation and synthesis, and hormone-mediated signal transduction. Notably, 16 transcription factors were identified as potential central regulators of the conserved stress response mechanisms.
conclusionsThis study reveals the diversity of drought response mechanisms among individual cotton species, identifies valuable targets for genetically enhancing drought tolerance, and provides a strategic framework for identifying candidate genes for breeding programs.
