Genome-wide characterization of NHX gene family in Medicago sativa under abiotic stress.
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 4 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
Soil salinization is one of the major abiotic stresses limiting global crop production. As key regulators of plant salt tolerance, the NHX gene family remains systematically uncharacterized in alfalfa (Medicago sativa). In this study, genome-wide analysis identified 35 NHX family genes (MsNHXs) in alfalfa, phylogenetically classified into three subfamilies. Subcellular localization prediction revealed that while six genes localized to the vacuole, the majority were distributed on plasma membranes, suggesting their primary contribution to salt tolerance through membrane-associated mechanisms. Tissue-specific expression analysis identified four genes (MsNHX7, MsNHX12, MsNHX21, and MsNHX24) with distinct tissue expression preferences. Analysis of abiotic stress responses demonstrated that MsNHX1 and MsNHX10 responded to salt, drought, and cold stress, while MsNHX1 and MsNHX19 were specifically induced by drought. cis-acting element analysis further revealed promoter enrichment in defense/stress-responsive and phytohormone-related elements, consistent with their roles in environmental adaptation. This study provides a theoretical foundation for elucidating salt tolerance mechanisms in alfalfa and supports its genetic improvement.
