The total planting area and yield of <em>C. oleifer</em>a in the province were 1.5 million hectares and 1.2 million tons, representing 32.9 % and 40.2 % of the China’s national totals, respectively. The core planting area was in Hengyang City, with a yield of 0.9 t ha⁻¹. <em>C. oleifera</em> was mainly planted in hilly regions with red and purple soils and high annual temperature. Random forest analysis identified key environmental factors influencing the yield of <em>C. oleifera</em>, including mean rainfall, temperature, and solar radiation from October to December, mean annual solar radiation and temperature, mean rainfall from July to September, altitude, aspect, clay content, and cation exchange capacity (CEC). The yield per unit area of <em>C. oleifera</em> was positively correlated with mean rainfall, temperature, and solar radiation from October to December, soil clay content, and CEC (<em>p</em> &lt; 0.05). The experimental results showed that in the <em>C. oleifera</em> plantation, the highest yield per plant (4.7 kg) was on the south-facing slope (Aspect = 180°). Intercropping with <em>Arachis hypogaea</em> and <em>Cassiae Semen</em> increased yields by 39.4 % and 28.1 %, respectively, compared to monoculture.

In this study, we thoroughly investigated the properties of Ov seeds and its oil. Ov seeds had a thousand seed weight of 3.1 g, bulk density of 591 g L⁻¹, and true density of 1144 g L⁻¹. The seeds had a high oil content of 42.2 wt% and crude protein and carbohydrate contents of 23.8 and 25.2 wt%, respectively. Different oil extraction methods were evaluated, and cold pressing followed by hexane extraction of the press cake yielded the highest amount of HFAs. The Ov oil contained 50.5 wt% of diunsaturated HFA wuhanic acid and 9.9 wt% of monounsaturated nebraskanic acid. The thermal properties of Ov oil were sufficient for use in industrial applications, with a pour point of −18 °C and an oxidation onset of 182.8 °C. The T_d95 of the oil under nitrogen atmosphere was 314.2 °C. The oil exhibited superb lubricant properties as determined by high frequency reciprocating rig (HFRR), with lower average wear scars and coefficient of frictions when compared to the petroleum-based lubricant PAO-6. Analysis of the glucosinolate content of the defatted seed meal indicated that it contained a high epiprogoitrin content of 69.80 µM g⁻¹. Other relevant oil properties were measured and compared to castor and lesquerella oils, two other HFA-containing oils.

Results showed anthocyanin content significantly increased during petal development, particularly at stage S3 where it increased 2.68-fold, coinciding with the transition from pale pink to bright red. Metabolomic analysis revealed a positive correlation between anthocyanin accumulation and total flavonoid content as petal development progressed, with the anthocyanin-to-total flavonoid ratio increasing from 0.30 at stage S1 to 0.55 at stage S4. This further supports the dominant role of anthocyanins in flower coloration. Transcriptome analysis identified 11,131 differentially expressed genes that exhibited stage-specific expression patterns, with significant enrichment in anthocyanin biosynthesis pathways at stage S3. Weighted gene co-expression network analysis (WGCNA) identified a regulatory module containing 41 transcription factors and 4 structural genes highly associated with anthocyanin accumulation. Notably, we discovered and validated a novel Li-miR828z-<em>LiMYB114</em> regulatory module using small RNA sequencing.

The augmented accessions were evaluated for 19 agro-morphological traits, including 13 quantitative and six qualitative traits, along with four check varieties at four different geographical locations in the winter season (2021–2022) through an Augmented Block Design. Five independent core sets were developed using compiled data on agro-morphological traits (standardized to eliminate scale differences) with Core Hunter in R, following optimization of average genetic distance-based criteria. Core size intensity was fixed at 300 accessions, which is approximately 10 % of the size of entire collection. Among the five, the core set EN100 was selected as the best representation based on the evaluation indices like, variance difference of 100 %, coincidence rate of 97.84 %, variable rate of coefficient of variation at 135.16 %, and mean difference at 46.15 %. The developed core collection was evaluated for its maximum diversity representation using the R package EvaluateCore. Diversity indices, Shannon-Weiner (1.014), McIntosh (0.26), and a lower Simpson’s Index (0.57) indicated high diversity in the selected core.

The effects of Cu-AC content on crosslink density, swelling behaviour, and curing characteristics were evaluated. SEM and EDX analyses confirmed good dispersion of Cu-AC particles, particularly at lower loadings. Mechanical testing revealed a significant increase in tensile strength and elongation at break, with the best balance of properties performed at 10 phr Cu-AC. Dielectric analysis showed increased interfacial polarization and charge storage, with the composite containing 15 phr Cu-AC exhibiting a dielectric constant of around 20 at 1 Hz, which is 2.68 times higher than that of neat NR. This enhancement was associated with interfacial polarization consistent with the Maxwell–Wagner–Sillars effect and the formation of conductive pathways by Cu-AC. However, due to reduced mechanical strength at higher loadings, the 10 phr Cu-AC composite was identified as the optimal formulation, offering a favourable combination of dielectric and mechanical performance. DFT calculations supported these findings, demonstrating strong NR–filler interactions, high adsorption energy (<em>E</em>_ads) and significant charge transfer for copper-doped surfaces.

This study aimed to elucidate these mechanisms by integrating phenotypic, physiological, transcriptomic, and metabolomic analyses. Four soybean varieties with differing salt and alkali tolerance—<em>Hedou NO. 6</em>, <em>Heihe 35</em>, <em>Zhonghuang 929</em>, and <em>Zhonghuang 911</em>—were screened based on comprehensive evaluations conducted at the Agricultural Research Institute. Phenotypic and agronomic traits confirmed their tolerance/sensibility at the seedling stage. The physiological results of the four soybean varieties under control, salt, alkali, and combined salt-alkali stress conditions indicated that combined salt-alkali stress induced unique physiological and biochemical responses, including increased reactive oxygen species and altered photosynthetic parameters. Targeted metabolomic and transcriptomic analyses of the tolerant varieties revealed that key regulatory pathways related to flavonoids, starch and sucrose, α-linolenic acid metabolism, and amino acid biosynthesis were identified as involved in this response, with significant upregulation of relevant genes and metabolites. Notably, key metabolites such as L-homocysteine (C00155), catechin (C06562) and kaempferol (C05903) were upregulated 2–64 fold under combined salt-alkali stress compared with the control. Additionally, key genes such as <em>HIDH</em> (K13258) and <em>AAT</em> (K14454) were upregulated by 2–29-fold under combined salt-alkali stress compared with the control group, indicating that they may be central to key regulatory pathways.

Our findings reveal significant structural variations and changes in gene content across <em>Opuntia</em> plastomes, with sizes ranging from 121,985 bp to 152,717 bp.

The O-H bond dissociation energy (BDE), molecular mobility, and oxygen barrier properties were comprehensively evaluated through a combination of quantum mechanics (QM), molecular dynamics (MD) and Monte Carlo (MC) simulations. Solubility parameter (<em>δ</em>) analysis showed that thymol, eugenol, and carvacrol exhibited the highest compatibility with PP, with thymol showing the smallest <em>δ</em> difference (1.366 (J·cm^-³) ¹^/²). Simulations demonstrated that thymol possesses outstanding free radical trapping ability, as evidenced by its relatively high bond dissociation energy (BDE: 163.728 kJ/mol), along with a low diffusion coefficient (<em>D</em>) (0.0112 × 10^-⁶ cm²/s), low permeability coefficient (<em>P</em>) (1.493 × 10^-⁹ cm²·s ^-¹·kPa^-¹), and a reduced reaction energy barrier, indicating long-term stability and highly efficient. The optimal antioxidant efficacy of thymol was systematically validated through thermo-oxidative aging experiments, employing advanced analytical techniques including X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), differential scanning calorimetry (DSC), melt flow rate (MFR) measurement, mechanical property characterization, and oxidation induction time (OIT) determination.
