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

backgroundArthrinium phaeospermum is the main pathogen causing shoot blight in Bambusa pervariabilis × Dendrocalamopsis grandis. Its SDR gene family, particularly ApSDR53C2, plays a key role in virulence, though its upstream regulation was unclear.

resultsThis study identified the minimal promoter region of ApSDR53C2 within the 0 to -184 bp segment and discovered the upstream transcription factor ApSP1 through yeast one-hybrid and dual-luciferase assays. Functional studies using silenced and overexpressed strains revealed that ApSP1 significantly affects fungal virulence, stress responses (oxidative, hyperosmotic, and heavy metal), and cell wall integrity. Furthermore, ApSP1 affects the ability of the strain to penetrate cellulose membranes by influencing the expression of the melanin synthesis-related genes ApCmr1 and ApLac1.

conclusionThese findings elucidate the upstream regulatory network of ApSDR53C2 and highlight ApSP1's multifunctional role in pathogenicity and environmental adaptation, offering insights for managing bamboo shoot blight.
