Auxin-Dependent Activation of RHD6-RSL4 Cascade Promotes Root Hair Growth Under Boron Deficiency in Arabidopsis Primary Root Apices.
Article in Plant, cell & environment, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Plants rapidly adjust their root system architecture to enhance resource uptake and cope with fluctuating soil environments. One such adaptive response is the development of root hairs (RH), which increase the effective root surface area and thereby improve water and nutrient acquisition. Here, we show that Arabidopsis seedlings respond rapidly to boron (B) deficiency by increasing both RH density and length at the root tip. This response is strongly correlated with enhanced auxin signaling in the root apex, as revealed by the auxin-responsive reporters IAA2::GUS and DR5rev:GFP. Our findings support the idea that B deficiency leads to auxin accumulation in the root tip, likely mediated by enhanced shoot-to-root auxin transport. Furthermore, by using pharmacological and genetic approaches, we provide evidence that enhanced auxin signaling via TIR1/AFBs in the RH zone activates the RHD6-RSL4 cascade to promote RH elongation under B deficiency. In contrast, the increase in RH density under B-deficient conditions appears to involve additional auxin-independent regulatory mechanisms.
