Metabolo-Transcriptomics Analyses Reveal Alfalfa Adaptation to Combined Saline-Alkali and Low-Temperature Stress in the Field.
Article in Plant biotechnology journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Alfalfa (Medicago sativa L.) is known as the 'King of Forage' because of its high protein content and excellent palatability. Alfalfa productivity is adversely affected in cold regions with saline-alkali soils. However, the mechanisms underlying the response of alfalfa to combined saline-alkali and low-temperature stress under field conditions remain unknown. The resistance of two alfalfa cultivars (resistant, ZD; sensitive, BM) in saline-alkali soil during cold and freezing periods was investigated using transcriptomic and metabolomic analyses. Metabolomic analysis revealed specific accumulation of amino acids, organic acids, carbohydrates, fatty acids and flavonoids in ZD compared with that in BM. The core differential metabolites associated with ZD stress resistance included isoleucine, fumaric acid, raffinose, 2-hydroxydocosanoic acid and isovitexin. Transcriptomic analysis revealed that ZD enriched more upregulated differentially expressed genes in galactose, starch and sucrose metabolism and flavonoid biosynthesis pathways than BM. Integrated metabolo-transcriptomic analysis highlighted flavonoid, carbohydrate, glutathione and salicylic acid biosynthesis as key pathways in alfalfa stress response. WGCNA identified 10 hub genes responsive to combined stress, with MsBAM1 potentially regulating the carbohydrate synthesis pathway and its silencing impaired alfalfa resistance to combined saline-alkali and low-temperature stress.
