IAA was involved in phosphorus deficiency-induced cluster roots formation in Macadamia integrifolia.
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 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
Phosphorus (P) deficiency induced the formation and development of cluster roots in macadamia, thereby stimulating P acquisition by enhancing root surface area and carboxylate exudation. However, how P deficiency regulates the formation of cluster roots in macadamia remains unclear. Sand culture experiments were conducted to investigate the role of auxin in formation cluster roots induced by P deficiency. Our results demonstrated that P deficiency significantly triggered the formation of cluster roots in macadamia, as evidenced by an increase in the number, carboxylates exudation and acid phosphatase activity. These differences might be attributed to the accumulation and distribution of IAA in cluster roots induced by P deficiency, as demonstrated by the positive effect of IAA application and inhibitory effect of NPA. Our results provide valuable insights into the mechanisms of cluster roots formation stimulated by P deficiency.
