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

MYB transcription factors play crucial roles in regulating plant growth and development, but the functions of the MYB-related subfamily in woody plants remain poorly understood. In this study, we characterized PagMYBR028, an MYB-related transcription factor from poplar '84 K' (Populus alba × Populus glandulosa), which was predominantly expressed in leaves and xylem. Compared with WT plants, PagMYBR028-overexpressing transgenic poplar exhibited reduced leaf area and retarded secondary xylem development, whereas PagMYBR028-RNAi lines displayed the opposite phenotypes. Further analysis revealed that PagMYBR028 interacts with PagMYBR005, a related regulator with overlapping functions in poplar development. Both proteins directly repress the expression of PagGRF12b, and their interaction enhances this transcriptional repression. In addition, overexpression of PagGRF12b promoted secondary cell wall deposition. Taken together, our results delineate a PagMYBR028-PagMYBR005-PagGRF12b module that coordinately regulates poplar growth and secondary wall development, providing new insights into the transcriptional network underlying wood formation and a theoretical basis for molecular breeding in trees.
