Genome-wide identification of the phosphofructokinase gene family in maize (Zea mays L.) and their expression levels under abiotic stress and phytohormones.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundPhosphofructokinase (PFK) is the primary rate-limiting enzyme and regulatory site of the glycolysis process, which is crucial for plant growth and the regulation of stress response. The PFK genes in Arabidopsis (Arabidopsis thaliana), wheat (Triticum aestivum), rice (Oryza sativa), cotton (Gossypium spp.) and potato (Solanum tuberosum) have been comprehensively analyzed. However, the PFK genes in maize (Zea mays L.) have not been systematically studied.
resultsIn this study, we performed a comprehensive bioinformatic analysis of the maize genome and identified 18 ZmPFK genes. Phylogenetic analysis indicated that these genes are divided into 5 subfamilies. The evolutionary patterns and divergence levels indicate that ZmPFK genes were present before the divergence of dicotyledons and have been highly conserved, undergoing purifying selection through out evolution. Expression analysis showed that most ZmPFK genes exhibited variable expression levels across different tissues and developmental stages. Based on transcriptome data and promoter element analysis, we specifically focused on eight ZmPFK genes whose promoters contained numerous plant hormones and stress response elements. These genes were up-regulated under different abiotic stresses as confirmed by RT-qPCR analysis, highlighting their important roles in plant growth and stress response.
conclusionsIn this study, the structure, location and evolutionary relationship of maize PFK gene family members were analyzed for the first time. We identified the ZmPFK genes involved in stress and plant hormone response by combining promoter element analysis, transcriptome data, and RT-qPCR analysis. This study provides valuable insights into the involvement of maize glycolysis in stress response.
