1 · What the graph read from it

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.

2 · The registry

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

Shoot branching is an important trait that influences plant architecture and crop productivity, and it is regulated by multiple plant hormones including strigolactones (SLs), auxin, and cytokinin; however, the interplay between them has yet to be fully elucidated. In this study, branching regulators were identified through a series of transcriptomic, functional and genetic studies. Based on results for gene expression that correlated with either bud outgrowth or bud growth suppression in petunia from a previous study, candidates for branching regulation were selected, and their functions in modulating branching were studied using Arabidopsis mutant lines. The SCARECROW-LIKE28 mutant (scl28) and CYTOKININ OXIDASE/DEHYDROGENASE3/5 double-mutant (ckx3 ckx5) showed significant reductions in rosette branching and altered flowering time relative to the wild type. Transcriptome comparisons between these mutants and the wild type suggested that up-regulation of SL biosynthesis genes in the mutants might contribute to the suppression of rosette branching. This was supported by genetic data indicating that SCL28 and CKX3/5 regulate rosette branching via the SL signalling pathway but regulate flowering independently. These findings provide new insights into the regulation and connections between SL and other hormones and developmental processes.
