（This article belongs to the Special Issue: Multi-Omics Insights into Plant Acclimation to Environmental Stress)
Abstract Recent efforts in crop improvement have increasingly focused on elucidating molecular-level regulatory mechanisms to develop high-yielding crops with enhanced tolerance to heavy metals (HMs) stress. Omics approaches, including genomics, transcriptomics, proteomics, metabolomics, ionomics, and phenomics, provide comprehensive analyses of plant responses to HMs stress. Genomics identifies stress-responsive genes, transcriptomics reveals dynamic changes in gene expression, proteomics evaluates protein abundance and post-translational modifications, and metabolomics characterize stress-related metabolites. Ionomics elucidates essential mineral dynamics involved in detoxification, while phenomics integrate high-throughput imaging with breeding techniques to evaluate stress resilience. Integration of multi-omics approaches provides a systems-level understanding… More >

（This article belongs to the Special Issue: The Biological Activity of Essential Oils, Volume II)
Abstract Essential oils (EOs) are most commonly characterized by GC–MS profiles and the relative abundance of dominant constituents. This approach is essential for chemical description and quality control, but it does not fully explain why EO composition differs among species, populations, organs, developmental stages, and growth conditions. Here, EO variability is examined from a focused, plant-centered perspective, with emphasis on terpenoid-rich systems in which glandular trichomes or other secretory structures are documented sites of volatile-metabolite biosynthesis, accumulation, or profile variation. The analysis centers on glandular trichomes as metabolic units, MEP/MVA precursor supply, prenyl diphosphate nodes, terpene… More >

Abstract Herbaceous peony (Paeonia lactiflora Pall.) is a traditional Chinese flower with high ornamental value. However, the antioxidant value of P. lactiflora petals has not been fully utilized, and the petals are often discarded as waste after flowering. Plant petals are typically rich in polyphenolic compounds with potent antioxidant properties, but research on the antioxidant properties of P. lactiflora petals remains insufficient. To investigate the antioxidant effects of P. lactiflora petal polyphenol extract (PPP), this study first determined and compared the PPP content of seven P. lactiflora cultivars, and then evaluated their antioxidant effects through in vitro and in vivo assays.

Abstract Water deficit and soil salinity can severely impair seed germination and crop establishment, creating a need for sustainable, non-chemical approaches to improve seed performance under stress. Electromagnetic-field (EMF) priming is a promising physical treatment; however, its effectiveness may depend strongly on the exposure regime and duration. This study evaluated the effect of electromagnetic-field (EMF) priming on broccoli (Brassica oleracea) seed germination under water and salt stress. Seeds were exposed to one or two EMF exposure regimes for different durations and were assessed through germination tests, digital image analysis, photoacoustic spectroscopy and FTIR spectroscopy. EMF priming produced… More >

Abstract Understory vegetation-mediated forest litter decomposition and nutrient release processes are critical for biogeochemical cycles and ecosystem sustainability. Drought-dominated global change significantly affects relevant processes, but its impact on metal element release from mixed litters of overstory trees and understory vegetation remains unclear. Here, we conducted an 18-month in situ decomposition experiment in a Pinus massoniana–Camellia oleifera mixed forest under three precipitation regimes: control (CK), low-intensity reduction (R30), and high-intensity reduction (R60). Both R30 and R60 treatments significantly inhibited P. massoniana litter mass loss by 4.85% and 6.22%, respectively. Only R60 treatment significantly reduced the mass loss in C. oleifera and… More >
