Chelation-based iron uptake mitigates the effects of prolonged high-temperature stress in cool-season grasses.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
High-temperature stress poses a significant threat to agricultural productivity and ecological diversity. Here, we show the effects of prolonged high-temperature stress on wheat (Triticum aestivum) and the model grass Brachypodium distachyon and demonstrate that heat stress induces iron deficiency in newly emerged leaves. Quantitative trait locus analysis of B. distachyon reveals a genomic region associated with heat resilience that includes the transporter of mugineic acid family phytosiderophores 1 gene (BdTOM1). Iron-deficiency-related genes including BdTOM1 are more highly expressed in a high-temperature-tolerant B. distachyon accession at high temperature than in a sensitive accession, resulting in greater secretion of deoxymugineic acid. Treatment with proline-2'-deoxymugineic acid mitigates heat-induced growth inhibition, but excess iron treatment leads to toxicity in both species. Our findings highlight the role of heat-induced nutritional stress in prolonged high-temperature stress and suggest that iron homeostasis could provide a promising target for improving crop resilience to climate extremes.
