Selection and validation of stable reference genes in potato infected by Pectobacterium atrosepticum using real-time quantitative PCR.
Article in Scientific reports, 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
Potato blackleg disease is caused by Pectobacterium atrosepticum, can seriously destroy potatoes' growth and development. To accurately evaluate the expression levels of genes involved in potato (Solanum tuberosum) responses to P. atrosepticum infection, seven candidate reference genes (EF1α, eIF5A3, Tubulin, Ubiquitin, GAPDH, Actin, and CYP3) were systematically assessed for their expression stability at 1, 3, and 5 days after inoculation (dai) using the geNorm, NormFinder, BestKeeper, ∆Ct, and RefFinder algorithms. The results demonstrated that EF1α exhibited the highest stability among all experimental conditions, followed by eIF5A3 and Tubulin, whereas Ubiquitin displayed the least stability. To validate the screening outcomes, the expression patterns of four disease resistance-related genes (RBOHC, WRKY24, MPK3, and CPK32) were analyzed in both resistant and susceptible potato cultivars using the EF1α as the most stable and Ubiquitin as the least stable. Validation experiments revealed that the expression levels of disease resistance-related genes were stable and consistent with the RNA-Seq data when EF1α was used as a reference gene. In contrast, using Ubiquitin as a reference gene led to significant variability. Therefore, EF1α can be employed as the reference gene when studying the interaction between the potato and P. atrosepticum, providing a standardized reference for the subsequent studies on screening of disease resistance genes and exploring of disease resistance mechanism in potato.
