Environmental adaptation in wheat landraces: integrating physiological, molecular, and ecological mechanisms for climate-resilient agriculture.
Review in Frontiers in plant science, 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
Climate change poses an increasing threat to wheat production, particularly in arid and semi-arid regions where rising temperatures, water scarcity, soil degradation, and salinity interact to reduce crop productivity and stability. Wheat landraces constitute an invaluable reservoir of adaptive genetic diversity that has evolved through centuries of natural and farmer-mediated selection under resource-limited environments. This review provides a comprehensive synthesis of the mechanisms underlying environmental resilience in wheat landraces, integrating evidence across physiological, biochemical, hormonal, molecular, ecological, and agronomic scales within a single framework. It examines how coordinated adaptive strategies-including stress escape, avoidance, tolerance, and recovery-interact with root system architecture, rhizosphere processes, plant-microbe associations, and resource-use efficiency to enhance resilience under multiple abiotic stresses. Recent advances in genomics, transcriptomics, proteomics, metabolomics, pangenomics, and multi-omics integration have substantially improved our understanding of the genetic and molecular basis of environmental adaptation, creating new opportunities for the identification and deployment of resilience-associated traits. The review further discusses how these discoveries are being translated into climate-smart wheat improvement through genome-wide association studies, marker-assisted and genomic selection, speed breeding, gene editing, and artificial intelligence-assisted phenotyping. In addition, sustainable agronomic management, conservation strategies, farmer participation, and policy frameworks are considered as complementary components supporting the effective utilization of wheat landraces. By integrating adaptive biology, modern breeding technologies, sustainable agronomy, and socio-economic perspectives, this review presents a comprehensive framework for conserving and utilizing wheat landrace diversity to accelerate the development of climate-resilient wheat cultivars and strengthen global food and nutritional security under increasingly unpredictable climatic conditions.
