Enhanced growth and productivity of useful metabolites by indole-3-propionic acid treatment in Lemna aequinoctialis culture.

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
backgroundLemna aequinoctialis is a floating plant with potential uses as food, feed, biofuel, biomass, and pharmaceutical resources. In this study, we examined the effect of various concentrations of indole-3-propionic acid (IPA) on the growth, metabolomic, and transcriptomic profiles of L. aequinoctialis cultures.
resultsIPA significantly improved the growth of L. aequinoctialis culture and altered its metabolome and transcriptome profiles. It also increased the cellular production of aspartate, glutamate, glutamine, serotonin, tryptophan, and phytosterols. Transcriptomic analysis revealed that 7,490 genes were significantly altered by the 10 µM IPA treatment. Metabolomic and transcriptomic profiling indicated that the IPA treatment notably altered the major pathways of 'glycerolipid metabolism', 'glutathione metabolism', 'β-alanine metabolism', 'alanine, aspartate, and glutamate metabolism', and 'starch and sucrose metabolism'. The highest productivities of serotonin, β-sitosterol, campesterol, and stigmasterol were observed on day 28 following treatment with 10 µM IPA.
conclusionsThe results of this study indicate that the application of IPA to L. aequinoctialis cultures significantly enhanced the growth and production of useful metabolites by affecting various metabolic pathways. This study is the first to investigate the biological effects of IPA on L. aequinoctialis, through an integrated analysis of metabolomics and transcriptomics. This could facilitate the large-scale cultivation of L. aequinoctialis for the application in various fields of agriculture and biotechnology including food, feed, and pharmaceutical industries.
