Effect of potent inhibitors of phenylalanine ammonia-lyase and PVP on in vitro morphogenesis of Fagopyrum tataricum.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 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
backgroundFagopyrum tataricum (Tartary buckwheat) is known for its high phenolic content, particularly rutin. High concentrations of these compounds secreted in the tissue culture medium can lead to its darkening and the eventual death of explants in in vitro cultures. This study aims to enhance the morphogenesis of F. tataricum callus cultures by utilising phenylalanine ammonia-lyase (PAL) inhibitors and polyvinylpyrrolidone (PVP) to mitigate oxidative browning and improve tissue viability.
resultsWe analysed the response of protoplasts isolated from morphogenic callus to media supplemented with varying concentrations of PAL inhibitors (AIP, AOPP, OBHA) and PVP. The flow cytometry results revealed that 10 µM AIP and 1% PVP yielded exclusively diploid plants, whereas higher concentrations (100 µM AIP and 3% PVP) failed to regenerate plants. Moreover, AOPP and OBHA addition resulted in the regeneration of tetraploid plants. Further analysis of proembryogenic cell complexes (PECCs) isolated from Tartary buckwheat morphogenic calli responses to AIP and PVP indicated that 100 µM AIP was most effective for plant regeneration. Metabolomic analysis showed that AIP treatments reduced phenolic compounds, notably rutin, and increased the GSH/GSSG ratio, indicating reduced oxidative stress. Gene expression analysis highlighted elevated expression of somatic embryogenesis-related genes (LEC2, BBM) and WUSCHEL in AIP-treated callus.
conclusionsThis study demonstrates that AIP enhances the regeneration potential of F. tataricum callus cultures, offering valuable insights for optimising tissue culture techniques for industrial crops. Additionally, we have detailed the metabolomic changes in calli treated with PVP and AIP, highlighting their impact on metabolism.
