Aromatic compounds play essential roles in plant physiology and various industries because of their unique fragrances and beneficial properties. In this study, we investigated the transport and biosynthesis of eugenol, a prominent aromatic compound, within the genus, using grafting experiments. Grafting sweet basil () scions onto diverse rootstocks, including tobacco () and thyme (), revealed that eugenol is transported from the shoot to the root across distinct plant species. Furthermore, grafting within the genus, which includes , , and , resulted in variations in eugenol transport and accumulation. The eugenol content in the shoots remained constant across all combinations, whereas the root eugenol levels varied depending on the scion-rootstock pair. To elucidate the biosynthetic capabilities of eugenol in roots, we performed in vitro enzyme assays using crude protein extracts from roots, which revealed that eugenol can be synthesized in roots in addition to being transported. Expression analysis of eugenol synthase (EGSs) genes showed that expression was influenced by grafting in roots, suggesting compensation by other EGSs. Our results suggest that eugenol transport and biosynthesis are multifaceted processes influenced by the interactions between different species and tissues. The potential to engineer eugenol levels in rootstocks lacking biosynthetic capacity has potential applications in agriculture and industry. This study reveals the dynamic interplay between eugenol transport and biosynthesis in the genus, providing insights into the manipulation of aromatic compound production in plants.

The early post-hatching phase remains to be one of the most vulnerable phases in broiler production. Some essential oils have been reported to improve gut health and growth in broiler chickens when applied to post-hatching diets. However, in-feed applications are unable to prevent the health challenges observed immediately after hatching.

This study aimed to evaluate the effects of liposome-encapsulated eugenol-based thiazolic derivatives against efflux pump-carrying bacteria. The Minimum Inhibitory Concentration (MIC) was determined to evaluate the antibacterial activity and antibiotic potentiation against Pseudomonas aeruginosa and Staphylococcus aureus, as well as to analyze the inhibition of efflux pumps in S. aureus strains 1199B and K2068 in the ethidium bromide assay.

is a rare and endangered plant endemic to China. It has high ornamental and potential economic and medicinal value, and is an important germplasm resource of Camellia. To understand the distributions and differences in metabolites from different parts of , in this study, we used liquid chromatography-tandem mass spectrometry (LC-MS/MS) to examine the types and contents of chemical constituents in five organs of : roots, stems, leaves, flowers, and fruits.

Several toxicogenic , such as and , could biosynthesize aflatoxin B (AFB) and other mycotoxins. Chemical fungicides are commonly used to control fungal contamination, but chemical residues may pose significant risks to human health and environmental stability. Consequently, natural antifungal and aflatoxin-inhibiting agents could be sustainable alternatives.
