A method for detecting transgenic rapeseed using pollen collected by Apis mellifera L.
Article in Transgenic research, 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
With the continuous expansion of the planting area of genetically modified (GM) crops, the demand for efficient and comprehensive monitoring systems is becoming increasingly urgent. To establish a method suitable for large-scale monitoring of genetically modified rapeseed planting, beehives were strategically deployed at specific locations around genetically modified rapeseed fields, and the TaqMan quantitative PCR (qPCR) method was used to detect and analyze the genetically modified components in the rapeseed pollen collected by bees. The results demonstrated that the average Ct values for the CaMV35S promoter, Bar gene, NPTII gene, and HPT gene in the pollen of each hive were 27.91, 29.58, 31.49, and 31.97, respectively. The average ΔCt values for these four genes in hive pollen from 100 to 200 m were - 0.35, 1.66, 2.58, and 5.06, respectively, which were significantly lower than those from 300 to 1100 m (2.85, 4.01, 6.66, and 5.63). The results of this study have demonstrated the feasibility of using pollen collected by bees for large-scale detection of genetically modified rapeseed plants. This early warning model for GM crop spread based on bee pollination provides an efficient and practical solution for monitoring and managing genetically modified crops.
