Genome-Wide Identification of COMT Gene Family in Maize and its Function in Response to Light.
Article in Biochemical genetics, 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
Maize is a major crop, feed, and industrial material. Caffeic acid-O-methyltransferase (COMT) is a methylase closely associated with lignin biosynthesis and plant growth and resistance. In this study, we identified the COMT gene (ZmCOMT) family in maize and further analyzed its phylogenetic evolution, subcellular localization, and its function in response to light. Thirty-one ZmCOMT genes were identified in the maize genome, which were distributed across eight chromosomes and mainly clustered on chromosome 4. Most ZmCOMT proteins were predicted to localize in the cytoplasm. Ten different conserved motifs were present in most ZmCOMT proteins, and motif1, motif6, and motif7 were highly conserved and present in all ZmCOMT proteins. The photoresponsivity elements were conserved among all members, and ZmCOMT22 and ZmCOMT10 genes responsive to light. This result suggests a potential function for these two genes in lignin biosynthesis which a previous study had linked to light regulation. Jasmonic acid responsive and abscisic acid cis-acting elements were present in the promoter regions of family members, thus the family may be regulated by hormone signaling pathways of maize. In summary, ZmCOMT genes are ancient, and the highly conserved motifs may be significant in survival and evolution of maize. Furthermore, light may influence lignin biosynthesis and photosynthesis through ZmCOMT genes. This research provided theoretical basis for lignin biosynthesis of maize and the potential value of ZmCOMT22 and ZmCOMT10 genes to enhance plant photosynthesis for facing global warming.
