Auxin promotes chloroplast division by increasing the expression of chloroplast division genes.
Article in Plant cell reports, 2024. 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
key messageAuxin stimulates chloroplast division by upregulating the expression of genes involved in chloroplast division and influencing the positioning of chloroplast division rings. Chloroplasts divide by binary fission, forming a ring complex at the division site. Auxin, particularly indole acetic acid (IAA), significantly influences various aspects of plant growth. However, the impact of auxin on chloroplast division remains unclear. In this study, different concentrations of exogenous IAA were applied to wild Arabidopsis thaliana. The results showed that the number and size differences of chloroplasts in the cells of Arabidopsis thaliana treated with high concentrations of IAA increased compared to untreated plants. Further investigation revealed that high concentrations of IAA affected the expression of chloroplast division genes and the formation of division rings. In chloroplast division mutants, the effect of IAA on promoting chloroplast division is impaired. Defects of IAA synthetic gene also lead to a reduced effect of IAA on chloroplast division. Our findings demonstrate that auxin influences chloroplast division by regulating the expressions of chloroplast division genes and affecting the localization of division rings. These results are significant for further exploring the relationship between auxin and chloroplast division.
