Summary: In this study, the phytotoxic potential of essential oil (EO) extracted from Carlina acaulis L. roots was tested against the weed Bidens pilosa L. The EO showed strong toxic effects on the plant metabolism, causing leaf necrosis, reduction in water content and leaf area, and an increase in dry weight/fresh weight ratio. It also damaged the photosynthetic machinery and altered the concentration of certain metabolites, indicating a reduction in photosynthetic efficiency. These findings suggest that C. acaulis EO has potential as a natural herbicide against weeds and requires further investigation.

Summary: The study confirmed the effectiveness of B. pilosa as a phytotherapy remedy against infectious disease. Higher concentrations of oligosaccharides, disaccharides, and fatty acids were found in the roots compared to other plant parts, while monoglycerides were more abundant in the stems. Peptides and diterpenoids were prominent in the leaves and roots, respectively.

Summary: This study investigates the use of citric acid, tartaric acid, and malic acid to enhance phytoremediation of Cd-contaminated soil by Bidens pilosa L. The results show that the addition of these organic acids can significantly increase the uptake and enrichment of heavy metals in plants, improving the overall phytoremediation efficiency.

Summary: Light regulation is considered an effective means of enhancing phytoremediation. This study investigated the effects of different light treatments on the growth and metal accumulation of Bidens pilosa L. Results showed that trichromatic light (red, blue, and green) influenced plant growth, photosynthesis, antioxidant enzyme activity, and soluble protein contents to a greater extent than bichromatic and monochromatic lights. Additionally, LED irradiation increased the abundance of rhizosphere microbes and soil enzyme activity. Overall, the R(20)B(70)G(10) trichromatic light efficiently induced plant Cd extraction and improved the phytoremediation of Cd-contaminated soils.

Summary: The chloroplast genomes of three endemic Chinese Bidens plants were sequenced, assembled, and annotated in this study. The results revealed a typical quadripartite structure and gene loss, and also suggested positive and purifying selection for certain chloroplast genes in Bidens. Phylogenetic analysis showed that these Bidens plants clustered together and formed a monophyletic clade with other Bidens species, indicating radiation adaptive selection. Additionally, inter-genic regions were identified as potential molecular markers for Bidens plant identification.

Summary: This study found that four polyacetylenes isolated from Bidens pilosa exhibited potent insecticidal activities against various pests, with compound 1 showing activity comparable to the commercial pesticide pyrethrins. These compounds also displayed inhibitory effects on GSTs and AChE in Plutella xylostella, indicating their potential as skin-safe insecticidal agents.

Summary: LEO was successfully nanoemulsified using a nanoemulsion technique to improve its water solubility and stability. The optimized preparation procedure resulted in LEO-NEs with small droplet size and good antioxidant activity. These findings provide a theoretical basis for the industrial application of lemon essential oil.

Summary: This study compared the accumulative properties of two ecotype hyperaccumulators of Bidens pilosa L. from different climate zones, revealing significant variations in Cd concentration and biomass between the ecotypes. The differences in Cd accumulation among ecotypes may be useful for identifying genes relevant to plant hyperaccumulation.

Summary: In this study, a pulse electric field was used as a pre-treatment to extract essential oil (EO) from coriander seeds. Different voltage and pulse number conditions were optimized, and the effects on EO extraction efficiency, phenolic content, antioxidant activity, oxidative stability, and microbial activity were measured. The best results were obtained at 1 kV/cm and 55 pulses, with linalool as the main constituent of coriander seeds EO. According to SEM results, coriander seeds EO exhibited inhibitory effects on bacterial cell walls.
