Hormonal diterpenoids derived from ent-kaurenoic acid are involved in the blue-light avoidance response of Physcomitrella patens.
Article in Plant signaling & behavior, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Gibberellins (GAs) are diterpenoid hormones that regulate growth and development in flowering plants. The moss Physcomitrella patens has part of the GA biosynthetic pathway from geranylgeranyl diphosphate to ent-kaurenoic acid via ent-kaurene, but it does not produce GA. Disruption of the ent-kaurene synthase gene in P. patens suppressed caulonemal differentiation. Application of ent-kaurene or ent-kaurenoic acid restored differentiation, suggesting that derivative(s) of ent-kaurenoic acid, but not GAs, are endogenous regulator(s) of caulonemal cell differentiation. The protonemal growth of P. patens shows an avoidance response under unilateral blue light. Physiological studies using gene mutants involved in ent-kaurene biosynthesis confirmed that diterpenoid(s) regulate the blue-light response. Here, we discuss the implications of these findings, and provide data for the ent-kaurene oxidase gene-disrupted mutant.
