Transcriptomic profiling and oxidative stress responses of Catharanthus roseus under short-term LED light exposure.
Article in BMC plant biology, 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
As the application of LED light on plants is increasing for development of efficient, sustainable, and innovative agricultural strategies, comprehensive knowledge towards response mechanisms of plants under such artificial light source is less known. To explore the molecular responses of Catharanthus roseus under short-term white LED light as guidance for optimizing its growth and therapeutic properties, transcriptomic sequencing-based investigation was performed. During 2 h of white LED light treatment, contents of catharanthine and vindoline fluctuated. The expression of genes involved in the methylthio-adenosine shunt pathway and its upstream regulatory components exhibited similar fluctuation trends. Circadian rhythm-related genes rapidly responded to the light exposure. Sugar metabolism showed dynamic changes, with a notable increase in glycosylation modifications, and antioxidant capacity was enhanced. These results highlight the initial responses of C. roseus to short-term white LED light and its broad regulatory effects on secondary metabolism, which facilitates the cultivation of C. roseus with enhanced therapeutic potential in an eco-friendly and commercially viable manner.
