Nutrient starvation and phosphonate utilization coordinate buoyancy and high-light tolerance in Trichodesmium.
Article in Nature communications, 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
The formation of surface blooms by the diazotrophic cyanobacterium Trichodesmium contributes extensively to carbon and nitrogen cycling. Yet the physiological drivers governing its vertical ascent and subsequent tolerance to high surface irradiance remain obscure. By measuring sinking and floating velocities, analyzing transcriptome responses, and tracking the subcellular distribution of gas vesicles, we show that nutrient starvation is the primary trigger for vertical ascent. Specifically, iron or phosphorus depletion inhibits metabolic ballasting, disrupting the equilibrium with gas vesicle lift and driving Trichodesmium towards surface waters. Moreover, this vertical migration is safeguarded by a light-dependent metabolic "safety brake" that prevents irreversible sinking to the deep ocean. Upon reaching the surface, Trichodesmium shifts to utilizing alternative organic phosphorus sources. Particularly, the utilization of methylphosphonate (MPn) activates a distinct "surface-survival mode" characterized by the downregulation of photosynthetic activity and the relocalization of gas vesicles to form peripheral optical shields. Our findings reveal a coordinated strategy linking nutrient sensing, buoyancy regulation, and photoprotection, explaining how Trichodesmium secures its ecological success under the high irradiance of the oligotrophic surface oceans.
