Quantitative assessment of hormogonia induction in Nostoc punctiforme by a fluorescent reporter strain.
Article in Journal of experimental botany, 2025. 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
While symbiotic plant-cyanobacteria interactions hold significant potential for revolutionizing agricultural practices by reducing the application of artificial nitrogen fertilizers, the genetic underpinnings of the symbiotic interaction between the plant host and the cyanobiont remain poorly understood. In particular, the molecular mechanisms through which host plants induce the formation of motile cyanobacterial filaments (hormogonia), essential for colonization and initiation of symbiosis, are not well characterized. In this study, we present a novel yet objective method for quantifying hormogonia induction, addressing limitations of traditional qualitative approaches. We have developed a reporter strain of Nostoc punctiforme PCC 73102 capable of quantifying hormogonia induction in response to diverse biotic and abiotic stimuli. This reporter strain, generated via triparental mating conjugation transformation, contains the promoter sequence of prepilin pilA fused to a green fluorescent protein (GFP) and enables quantitative and high-throughput monitoring of hormogonia induction using a microplate reader. Our innovative approach, employing a cyanobacterial hormogonia reporter strain, allows high-throughput screening of the hormogonia-inducing effect of a wide array of environmental and plant signals. This method is expected to greatly advance our understanding of the genetic determinants underpinning plant-cyanobacteria symbioses.
