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

backgroundThe seeds of Toxicodendron vernicifluum (Stokes) F. A. Barkley are rich in oils and hold significant economic value in industrial and food applications, yet the molecular mechanisms underlying lipid biosynthesis are not fully elucidated, which hinders targeted improvement efforts.

resultsTo investigate the genetic and metabolic basis of oil accumulation, this study first surveyed and collected seeds from 36 distinct half-sib familys across three provenances in Yunnan Province, China. Seed morphology and oil content measurements revealed the most significant oil content difference between the LS1 and YG6 families. Subsequently, integrated lipidomic and transcriptomic analyses were performed to identify differential metabolites (DEMs) and differential genes (DEGs) related to lipid synthesis in seeds of these two families. Lipidomics results identified 221 lipid DEMs (51 up-regulated, 170 down-regulated). Transcriptomics detected 6,658 DEGs (1,800 up-regulated, 4,858 down-regulated). Integrated analysis revealed significant enrichment of DEMs and DEGs in glycerophospholipid metabolism and ether lipid metabolism, suggesting that these pathways are key regulators of Toxicodendron vernicifluum oil composition. Among these pathways, three key lipid metabolites were identified: phosphatidylcholine (PC), 1-alkyl-sn-glycerol-3-phosphocholine (1-alkyl-G3P), and 1-acyl-sn-glycerol-3-phosphocholine (1-acyl-G3P).

conclusionThis research establishes a foundational framework for elucidating lipid synthesis and accumulation in Toxicodendron vernicifluum seeds and provides critical insights for future targeted breeding and utilization strategies.
