Ricinus communis, a plant of significant industrial value for its oil, is renowned for its robust root system and vigorous growth, qualities that render it an exemplary candidate for the ecological remediation of soils contaminated with heavy metals. The impact of heavy metal stress on root development is characterized by inhibition, a phenomenon whose underlying mechanisms are not fully elucidated. To shed light on this, a study was conducted wherein varying concentrations of the exogenous auxin, IBA, were applied to the roots of Ricinus communis to scrutinize its influence on the endogenous indole-3-acetic acid (IAA) metabolism in seedlings and to delineate the molecular underpinnings of its effects on root morphology.

However, the comprehension of the distinctive oil biosynthesis and deposition strategies within the fruit's various compartments, coupled with the tissue-specific biosynthetic pathways yielding optimal fatty acid profiles, remains in its infancy. This investigation was designed to delineate the tissue specificity of oil biosynthetic disparities and to elucidate the molecular underpinnings within the fruit mesocarp and seeds of , employing lipidomic and transcriptomic analyses.

Previous studies have shown significant differences in the stability of Pickering emulsions composed of different oil phases and in the bioaccessibility of the encapsulated functional ingredients. This study therefore investigated the effects of different carrier oils in the betulin self-stabilized water-in-oil (W/O) Pickering emulsion on the stability of the emulsion and bioaccessibility of betulin.

In this study, a comprehensive method was established to overcome seed dormancy by subjecting seeds to scarification in 98% HSO for 10 min, followed by 1000 mg·L GA soaking for 48 h and stratification at 4 °C for 100 days. The seed germination percentage has increased significantly, to a peak of 42.

This study selected linseed, rapeseed, sunflower, coconut, and palm oils to combine with the triterpenoid compound β-amyrin for the preparation of oleogels. The stability, crystal network structure, and other properties of each oleogel were evaluated.

And its oil synthesis is intricately linked to the accumulation and transformation of sugars. Nevertheless, there remains a dearth of understanding regarding how sugar metabolism impacts oil synthesis in fruit.

This could be enhanced by changing the food matrix of UA in which it is present. In this study, several UA systems were constructed to investigate the bioaccessibility and bioavailability of UA in combination with in vitro simulated digestion and Caco-2 cell models.

However, whether and how these functions are conserved becomes less clear when neighboring amino acids are not conserved. Here, we investigate one such case, focused on the highly conserved residue from P2X4, E118 (rat P2X4 numbering, rP2X4), a P2X subtype associated with human neuropathic pain.

View Article and Find Full Text PDFPlant microRNAs (miRNAs) are single-stranded RNA molecules of around 22 nucleotides (nt) in length that are associated with the RNA-induced silencing complex (RISC). They act as post-transcriptional negative regulators of gene expression mainly by guiding cleavage or attenuating the translation of target transcripts. The targets of plant miRNAs often belong to transcription factors families involved in the control of developmental processes and defense responses.
