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

Vascular development and secondary growth are essential processes in woody plants, governed by intricate gene regulatory networks. The succinate dehydrogenase (SDH) gene family is thought to play a role in multiple plant growth processes and may influence vascular development and secondary growth by regulating energy metabolism and related developmental processes. This study involved a thorough analysis and functional validation of the poplar SDH gene family, emphasizing their involvement in vascular development. Twelve potential poplar SDH genes were identified through homologous search with Arabidopsis thaliana, and their evolutionary relationships were verified using phylogenetic analysis. Structural and motif analysis identified conserved domains, notably in PtrSDH1 and PtrSDH4, implicating their participation in fundamental metabolic processes. Expression analysis showed that PtrSDH1 and PtrSDH4 were significantly upregulated in the cambium and xylem, two tissues that are fundamental for vascular development. The study used the SDH4 gene PagSDH4 from 84 K poplar as the research object. Functional verification was performed by overexpressing PagSDH4 in transgenic poplars. The results showed that the gene promoted growth, increased xylem width, and increased stem diameter in the overexpressing plants, thereby promoting vascular tissue formation and biomass accumulation. This suggests that PtrSDH4 plays a key regulatory role in cambium activity. The study underscores the potential of SDH genes for genetic improvement in tree growth and wood production.
