Analysis of lipidomics profile of Brassica napus hybrid 'Fangyou 777' and its parents during ripening stages based on UPLC-MS/MS.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundLipids in rapeseed is of great significance to human health, and 'Fangyou 777' (No. GPD-2019-510073) has been identified as an excellent cultivar with high oil content. However, the change of lipid profile at different ripening stages remain unclear. Herein, UPLC-MS/MS was utilized for comprehensive lipidomics analysis of 'Fangyou 777' and its parents at four ripening stages.
results778 lipids components across 25 subclasses were identified, and triglycerides (TGs), diglycerides (DGs), phosphatidylserines (PSs), phosphatidylinositols (PIs), phosphatidylglycerols (PGs), phosphatidylcholines (PCs), phosphatidylethanolamines (PEs), and free fatty acids (FFAs) were identified as the dominant lipid subclass. Due to heterotic vigor, the total lipids, TGs, FFAs, lysophosphatidylglycerol (LPGs) and PSs contents in 'Fangyou 777' were significantly higher than its parents. The PCA and OPLS-DA results elucidated that lipids in 'Fangyou 777' differed obviously from its parents at S1 (17 April, 2023; 28 days before ripening, 28 DBR), S2 (1 May, 2023; 14 DBR), and S3 (15 May, 2023; ripening day). TG(18:1_18:3_22:1), TG(18:1_22:1_18:2), TG(16:0_18:1_20:1), TG(16:0_18:1_22:1), TG(20:1_18:2_20:2), TG(18:1_18:1_20:1), and FFA(24:4) were recognized as key differential lipids. The glycerolipid metabolism and unsaturated fatty acid biosynthesis were the differential metabolic pathways at S1 and S3, while glycosylphosphatidylinositol (GPI)-anchor biosynthesis and glycerophospholipid metabolism were the differential metabolic pathways at S2 and S4 (7 days after ripening/physiologically ripened for one week).
conclusionThis study provided a comprehensive profile to facilitate the understanding lipids accumulation in 'Fangyou 777' and its parents during ripening stages, and offered a foundation to comprehend lipid metabolism.
